Given the hierarchical organization of syntactic units that he posited (and represented using stemmas), Tesnière identified centripetal and centrifugal structures.The distinction between centripetal and centrifugal structures is first presented in chapter 8 (1966:22ff.). The modern terms for these concepts are head-initial (centrifugal) and head-final (centripetal). Centrifugal structures see governors (heads) preceding their dependents, whereas the situation is reversed for centripetal structures, the dependents preceding their heads, e.g.

The Semitic languages (e.g. Hebrew, Arabic) are, for instance, much more centrifugal than centripetal, and certain East Asian languages are much more centripetal than centrifugal (e.g. Japanese, Korean).

A body experiencing uniform circular motion requires a centripetal force, towards the axis as shown, to maintain its circular path. In the case of an object that is swinging around on the end of a rope in a horizontal plane, the centripetal force on the object is supplied by the tension of the rope. The rope example is an example involving a 'pull' force. The centripetal force can also be supplied as a 'push' force, such as in the case where the normal reaction of a wall supplies the centripetal force for a wall of death rider.

Newton's idea of a centripetal force corresponds to what is nowadays referred to as a central force. When a satellite is in orbit around a planet, gravity is considered to be a centripetal force even though in the case of eccentric orbits, the gravitational force is directed towards the focus, and not towards the instantaneous center of curvature. Another example of centripetal force arises in the helix that is traced out when a charged particle moves in a uniform magnetic field in the absence of other external forces. In this case, the magnetic force is the centripetal force that acts towards the helix axis.

The companion paper is However, the Lagrangian use of "centrifugal force" in other, more general cases has only a limited connection to the Newtonian definition. In another instance the term refers to the reaction force to a centripetal force, or reactive centrifugal force. A body undergoing curved motion, such as circular motion, is accelerating toward a center at any particular point in time. This centripetal acceleration is provided by a centripetal force, which is exerted on the body in curved motion by some other body.

This gyration continually displaces the tube with a component along the direction of the centripetal force acting on the projectile, so that work is continually done on the projectile as it advances through the machine.

As described, cant may be used to reduce lateral acceleration on trains traveling on curved track. This is to balance the centrifugal force (force pushing outward the curve) and centripetal force (force pushing inward the curve). At a higher speed, the centrifugal force is higher. On the contrary, higher cant creates the higher centripetal force.

A centripetal force directed towards the center of the turn is required for any object to move in a circular path. In the context of a rotating space station it is the normal force provided by the spacecraft's hull that acts as centripetal force. Thus, the "gravity" force felt by an object the centrifugal force perceived in the rotating frame of reference as pointing "downwards" towards the hull. In accordance with Newton's Third Law the value of little g (the perceived "downward" acceleration) is equal in magnitude and opposite in direction to the centripetal acceleration.

Frye uses the terms 'centripetal' and 'centrifugal' to describe his critical method. Criticism, Frye explains, is essentially centripetal when it moves inwardly, towards the structure of a text; it is centrifugal when it moves outwardly, away from the text and towards society and the outer world. Lyric poetry, for instance, like Keats's "Ode on a Grecian Urn", is dominantly centripetal, stressing the sound and movement and imagery of the ordered words. Rhetorical novels, like Uncle Tom's Cabin, are dominantly centrifugal, stressing the thematic connection of the stories and characters to the social order.

In computer vision, centripetal Catmull-Rom spline has been used to formulate an active model for segmentation. The method is termed active spline model. The model is devised on the basis of active shape model, but uses centripetal Catmull-Rom spline to join two successive points (active shape model uses simple straight line), so that the total number of points necessary to depict a shape is less. The use of centripetal Catmull-Rom spline makes the training of a shape model much simpler, and it enables a better way to edit a contour after segmentation.

One common example involving centripetal force is the case in which a body moves with uniform speed along a circular path. The centripetal force is directed at right angles to the motion and also along the radius towards the centre of the circular path. The mathematical description was derived in 1659 by the Dutch physicist Christiaan Huygens.

Theorem 3 now evaluates the centripetal force in a non-circular orbit, using another geometrical limit argument, involving ratios of vanishingly small line-segments. The demonstration comes down to evaluating the curvature of the orbit as if it were made of infinitesimal arcs, and the centripetal force at any point is evaluated from the speed and the curvature of the local infinitesimal arc. This subject reappears in the Principia as Proposition 6 of Book 1. A corollary then points out how it is possible in this way to determine the centripetal force for any given shape of orbit and center.

This force is directed inward, along the direction of the string, and is called a centripetal force. The other ball has the same requirement, but being on the opposite end of the string, requires a centripetal force of the same size, but opposite in direction. See Figure 2. These two forces are provided by the string, putting the string under tension, also shown in Figure 2.

A body experiencing uniform circular motion requires a centripetal force, towards the axis as shown, to maintain its circular path. In 1659, Christiaan Huygens coined the term "centrifugal force" and was the first to derive the now standard mathematical description for the centripetal force. Christiaan Huygens stated what is now known as the second of Newton's laws of motion in a quadratic form.Ernst Mach, The Science of Mechanics (1919), e.g. p. 143, p. 172 and p. 187 . In 1659 he derived the now standard formula for the centripetal force, exerted by an object describing a circular motion, for instance on the string to which it is attached.

But , and . The integral of the equation for centripetal acceleration, which will over a distance will thus yield :p-p_\infty \approx - \rho U^2 \,. The exact solution has, for the lowest pressure, :p-p_\infty = - \tfrac32 \rho U^2 \,. The low pressure, which must be present to provide the centripetal acceleration, will also increase the flow speed as the fluid travels from higher to lower values of pressure.

Solving applications dealing with non-uniform circular motion involves force analysis. With uniform circular motion, the only force acting upon an object traveling in a circle is the centripetal force. In non-uniform circular motion, there are additional forces acting on the object due to a non-zero tangential acceleration. Although there are additional forces acting upon the object, the sum of all the forces acting on the object will have to equal to the centripetal force.

The following two trees of the English sentences Stop attempting to do that and His sister's attempts succeeded illustrate the distinction: ::Stemmas 3 The stemmas clearly show the manner in which centrifugal structures extend down to the right, and centripetal structures down to the left.

Languages are classified in terms of their head-directionality parameter: as predominantly head-initial or head-final.

In classical mechanics, a reactive centrifugal force forms part of an action–reaction pair with a centripetal force. In accordance with Newton's first law of motion, an object moves in a straight line in the absence of any external forces acting on the object. A curved path may however ensue when a force acts on it; this force is often called a centripetal force, as it is directed toward the center of curvature of the path. Then in accordance with Newton's third law of motion, there will also be an equal and opposite force exerted by the object on some other object, such as a constraint that forces the path to be curved, and this reaction force, the subject of this article, is sometimes called a reactive centrifugal force, as it is directed in the opposite direction of the centripetal force.

Animation depicting evolution of a Cornu spiral with the tangential circle with the same radius of curvature as at its tip, also known as an osculating circle. To travel along a circular path, an object needs to be subject to a centripetal acceleration (e.g.: the moon circles around the earth because of gravity; a car turns its front wheels inward to generate a centripetal force). If a vehicle traveling on a straight path were to suddenly transition to a tangential circular path, it would require centripetal acceleration suddenly switching at the tangent point from zero to the required value; this would be difficult to achieve (think of a driver instantly moving the steering wheel from straight line to turning position, and the car actually doing it), putting mechanical stress on the vehicle's parts, and causing much discomfort (due to lateral jerk).
|
|
Another common mistake is to state that "the centrifugal force that an object experiences is the reaction to the centripetal force on that object." If an object were simultaneously subject to both a centripetal force and an equal and opposite centrifugal force, the resultant force would vanish and the object could not experience a circular motion. The centrifugal force is sometimes called a fictitious force or pseudo force, to underscore the fact that such a force only appears when calculations or measurements are conducted in non-inertial reference frames.

On early railroads this instant application of lateral force was not an issue since low speeds and wide-radius curves were employed (lateral forces on the passengers and the lateral sway was small and tolerable). As speeds of rail vehicles increased over the years, it became obvious that an easement is necessary, so that the centripetal acceleration increases linearly with the traveled distance. Given the expression of centripetal acceleration , the obvious solution is to provide an easement curve whose curvature, , increases linearly with the traveled distance. This geometry is an Euler spiral.

A centripetal force (from Latin centrum, "center" and petere, "to seek" Extract of page 291) is a force that makes a body follow a curved path. Its direction is always orthogonal to the motion of the body and towards the fixed point of the instantaneous center of curvature of the path. Isaac Newton described it as "a force by which bodies are drawn or impelled, or in any way tend, towards a point as to a centre". In Newtonian mechanics, gravity provides the centripetal force causing astronomical orbits.
|
|
The argument is also spelled out by Bruce Pourciau in "From centripetal forces to conic orbits: a path through the early sections of Newton's Principia", Studies in the History and Philosophy of Science, 38 (2007), pp.56–83.

For example, it cannot happen that the string breaks under extreme tension in one frame of reference and remains intact in another frame of reference, just because we choose to look at the string from a different frame. If the spheres only appear to rotate (that is, we are watching stationary spheres from a rotating frame), the zero tension in the string is accounted for by observing that the centripetal force is supplied by the centrifugal and Coriolis forces in combination, so no tension is needed. If the spheres really are rotating, the tension observed is exactly the centripetal force required by the circular motion. Thus, measurement of the tension in the string identifies the inertial frame: it is the one where the tension in the string provides exactly the centripetal force demanded by the motion as it is observed in that frame, and not a different value.

Derivation of the formula for motion along the Equator. A convenient coordinate system in this situation is the inertial coordinate system that is co-moving with the center of mass of the Earth. Then the following is valid: objects that are at rest on the surface of the Earth, co-rotating with the Earth, are circling the Earth's axis, so they are in centripetal acceleration with respect to that inertial coordinate system. What is sought is the difference in centripetal acceleration of the surveying airship between being stationary with respect to the Earth and having a velocity with respect to the Earth.

To see this unstable behavior more quantitatively, consider the equations of motion for a fluid element mass in circular motion with an angular velocity \Omega\ . In general \Omega will be a function of the distance from the rotation axis R\ , and we assume that the orbital radius is r=R_0\ . The centripetal acceleration required to keep the mass in orbit is -R\Omega^2(R)\ , the minus sign indicates a direction toward the center. If this force is gravity from a point mass at the center, then the centripetal acceleration is simply -GM/R^2, where G is the gravitational constant and M is the central mass.

Angle ω dt is the very small angle between the two velocities and tends to zero as dt→ 0. Figure 3: (Left) Ball in circular motion – rope provides centripetal force to keep ball in circle (Right) Rope is cut and ball continues in straight line with velocity at the time of cutting the rope, in accord with Newton's law of inertia, because centripetal force is no longer there. In physics, uniform circular motion describes the motion of a body traversing a circular path at constant speed. Since the body describes circular motion, its distance from the axis of rotation remains constant at all times.

Considering walking with the inverted pendulum model, one can predict maximum attainable walking speed with the Froude number, F = v^2 / lg, where v^2 = velocity squared, l = leg length, and g= gravity. The Froude number is a dimensionless value representing the ratio of Centripetal force to Gravitational force during walking. If the body is viewed as a mass moving through a circular arc centered over the foot, the theoretical maximum Froude number is 1.0, where centripetal and gravitational forces are equal. At a number greater than 1.0, the gravitational force would not be strong enough to hold the body in a horizontal plane and the foot would miss the ground.

However, the object is moving in a circular path as the Earth rotates and therefore experiencing a centripetal acceleration. When considered in an inertial frame (that is to say, one that is not rotating with the Earth), the non-zero acceleration means that force of gravity will not balance with the force from the spring. In order to have a net centripetal force, the magnitude of the restoring force of the spring must be less than the magnitude of force of gravity. Less restoring force in the spring is reflected on the scale as less weight — about 0.3% less at the equator than at the poles.

America has crippled harmony. Harmony is individualism and sociability. The North embodies individualism; the South, sociability. The Saxon-Yankee is Protestant and federal; the Spanish American is Catholic and a centralizer... the Yankee is the centrifugal force; the American from the South is the centripetal force.

They are separated into four groups, "Tornado Battlers" (taller, all plastic), "Electro Battlers" (light and sound effects), "IR Spin Control Beyblades" (remote controlled), and ¨Stealth Battlers¨ (hidden weapons released by centripetal force). None of these can be customized.

Scientists are concerned about the effect of such a system on the inner ear of the occupants. The concern is that using centripetal force to create artificial gravity will cause disturbances in the inner ear leading to nausea and disorientation. The adverse effects may prove intolerable for the occupants.

Internal tensile stress provides the centripetal force that keeps a spinning object together. A rigid body model neglects the accompanying strain. If the body is not rigid this strain will cause it to change shape. This is expressed as the object changing shape due to the "centrifugal force".

Westfall, pp. 391–92 After the exchanges with Hooke, Newton worked out proof that the elliptical form of planetary orbits would result from a centripetal force inversely proportional to the square of the radius vector (see Newton's law of universal gravitation – History and De motu corporum in gyrum).

At low speeds, the spring provides the centripetal force to the shoes, which move to larger radius as the speed increases and the spring stretches under tension. At higher speeds, when the shoes can't move any further out to increase the spring tension, due to the outer drum, the drum provides some of the centripetal force that keeps the shoes moving in a circular path. The force of tension applied to the spring, and the outward force applied to the drum by the spinning shoes are the corresponding reactive centrifugal forces. The mutual force between the drum and the shoes provides the friction needed to engage the output drive shaft that is connected to the drum.

Newton himself appears to have previously supported an approach similar to that of Leibniz. Later, Newton in his Principia crucially limited the description of the dynamics of planetary motion to a frame of reference in which the point of attraction is fixed. In this description, Leibniz's centrifugal force was not needed and was replaced by only continually inward forces toward the fixed point. Newton objected to Leibniz's equation on the grounds that it allowed for the centrifugal force to have a different value from the centripetal force, arguing on the basis of his third law of motion, that the centrifugal force and the centripetal force must constitute an equal and opposite action-reaction pair.

This was given by Isaac Newton through his Inverse Square Law. (Proposition 4), and relationships between centripetal forces varying as the inverse-square of the distance to the center and orbits of conic-section form (Propositions 5–10). Propositions 11–31 establish properties of motion in paths of eccentric conic-section form including ellipses, and their relation with inverse-square central forces directed to a focus, and include Newton's theorem about ovals (lemma 28). Propositions 43–45 are demonstration that in an eccentric orbit under centripetal force where the apse may move, a steady non-moving orientation of the line of apses is an indicator of an inverse- square law of force.

Diagram of a hydrocyclone: A hydrocyclone (often referred to by the shortened form cyclone) is a device to classify, separate or sort particles in a liquid suspension based on the ratio of their centripetal force to fluid resistance. This ratio is high for dense (where separation by density is required) and coarse (where separation by size is required) particles, and low for light and fine particles. Hydrocyclones also find application in the separation of liquids of different densities. A different description: A hydrocyclone is a mechanical device designed to reduce or increase the concentration of a dispersed phase, solid, liquid or gas of different density, by means of centripetal forces or centrifugal forces within a vortex.

Centripetal Acceleration is generally sufficient to maintain line tension if the airplane is properly "trimmed" (adjusted), but sometimes additional features such as rudder offset and engine offset are added to provide extra tension. It is of interest to note, that when a control line model does a loop, it no longer flies on the edge of a hemisphere, but traverses the edge of a cone, a planar path, and the motion of the model produces no centripetal acceleration. In the condition of flying a loop, other factors must therefore provide the line tension, such as engine offset, or lead-out rake. Weight in the outboard wing tip is usually used to balance the weight of the lines.

In regard to evidence that still survives of the earlier history, manuscripts written by Newton in the 1660s show that Newton himself had, by 1669, arrived at proofs that in a circular case of planetary motion, "endeavour to recede" (what was later called centrifugal force) had an inverse-square relation with distance from the center.See especially pp. 13–20 in After his 1679–1680 correspondence with Hooke, Newton adopted the language of inward or centripetal force. According to Newton scholar J. Bruce Brackenridge, although much has been made of the change in language and difference of point of view, as between centrifugal or centripetal forces, the actual computations and proofs remained the same either way.

The following areas are touched on: (1) connections, (2) autonomous syntax, (3) verb centrality, (4) stemmas, (5) centripetal (head- initial) and centrifugal (head-final) languages, (6) valency, (7) actants and circonstants, and (8) transfer.

The forces at play in the case of a curved surface. Red: gravity Green: the normal force Blue: the net resultant centripetal force. To demonstrate the Coriolis effect, a parabolic turntable can be used. On a flat turntable, the inertia of a co- rotating object forces it off the edge.

Sometimes rain tyres are designed to have a smaller diameter than their dry counterparts. This means that the wheel spins faster and more water is thrown off the tyre by overcoming centripetal force. Some rain tyres are also narrower than the dry counterparts. This smaller "footprint" reduces the chances of hydroplaning.

The force of gravity and the normal force. The resultant force acts as the required centripetal force. The mathematical derivation for the Eötvös effect for motion along the Equator explains the factor 2 in the first term of the Eötvös correction formula. What remains to be explained is the cosine factor.

Centripetal Catmull–Rom spline has several desirable mathematical properties compared to the original and the other types of Catmull-Rom formulation. First, it will not form loop or self-intersection within a curve segment. Second, cusp will never occur within a curve segment. Third, it follows the control points more tightly.

What is experienced by the physically rotating observer is the centripetal force and the physical effect arising from his own inertia. The effect arising from inertia is referred to as reactive centrifugal force. Whether or not the effects from inertia are attributed to a fictitious centrifugal force is a matter of choice.

The report called for the creation of the CDC center. Ommaya’s research provided the experimental data needed to model traumatic brain injury. His Centripetal theory was foundational to the biomechanics of traumatic brain injury. This work allowed for improved modeling of brain injury by engineers in their design of safety equipment in automobiles.

The vertical loop is not a recent roller coaster innovation. Its origins can be traced back to the 1850s when centrifugal railways were built in France and Great Britain. The rides relied on centripetal forces to hold the car in the loop. One early looping coaster was shut down after an accident.

Hence, at 60 degrees latitude, any object co-moving with the Earth has its weight reduced by about 0.08 percent, thanks to the Earth's rotation. Calculating the Eötvös effect: When the airship is cruising at 25 m/s towards the east the total velocity becomes 233 \+ 25 = 258 m/s, which requires a centripetal force of about 0.208 newton; local vertical component about 0.104 newton. Cruising at 25 m/s towards the west the total velocity becomes 233 − 25 = 208 m/s, which requires a centripetal force of about 0.135 newton; local vertical component about 0.068 newton. Hence at 60 degrees latitude the difference before and after the U-turn of the 10,000 gram internal weight is a difference of 4 grams in measured weight.

As seen in a rotating reference frame that matches the angular velocity of the two co- orbiting bodies, the gravitational fields of two massive bodies combined providing the centripetal force at the Lagrangian points, allowing the smaller third body to be relatively stationary with respect to the first two."Lagrange Points" by Enrique Zeleny, Wolfram Demonstrations Project.

Huygens stated what is now known as the second of Newton's laws of motion in a quadratic form.Ernst Mach, The Science of Mechanics (1919), e.g. pp. 143, 172, 187 . In 1659 he derived the now standard formula for the centripetal force, exerted on an object describing a circular motion, for instance by the string to which it is attached.

This increases the normal reaction on the outer wheels. Due to increase in normal reaction, the frictional force on the outer tyres also increase. This friction acts as centripetal force and tries to bend the outer tires inwards. The tires get deformed due to bending and the contact area between the wheels and the ground decreases.

The 799 cc engine, originally designed by Ezio Mascheroni and first fitted to the F3, uses a DOHC inline three-cylinder layout with four valves per cylinder. A counter-rotating (reverse) crankshaft is used, which counteracts the centripetal forces of the wheels allowing the bike to turn faster. The bore and stroke are 79 mm and 54.3 mm.

Two commonly used forced-induction compressors are turbochargers and superchargers. A turbocharger is a centripetal compressor driven by the flow of exhaust gases. Superchargers use various different types of compressors but are all powered directly by the rotation of the engine, usually through a belt drive. The compressor can be centrifugal or a Roots-type for positive displacement compression.

The lower ring of louvers (3) convey large masses of air (33) almost directly into the low-pressure end of the vortex. The lower ring of louvers (3) are crucial to get high mass flows, because air from them (33) spins more slowly, and thus has lower centripetal forces and a higher pressure at the vortex.

Friction therefore produces a centripetal force upon the mass of tea leaves. This boundary layer causes a secondary flow schema, ultimately resulting in a spiral. The primary flow schema, caused by the stirring, forces water outward and up the edge of the cup. Then, under increasing pressure, water moves downward, inward and then upward, about the centre (see diagram).

This way the scroll is transporting the settled particles along the cylindrical part of the bowl and up to the end conical part of the bowl. At the smallest end of the conical part of the bowl, the dewatered solids leave the bowl via discharge opening. The clarified liquid leaves through a paring disc (internal centripetal pump).

When the counter flow drag force outweighs the centripetal force, particles will be driven by the net force and leave the chamber. Smaller particles are able to leave the chamber at lower flow rates. In contrast, larger particles will stay within the elutriation chamber. Therefore, buffer flow rate can be used to control size sorting within the elutriation chamber.

The morphemes of the verb are ordered in the complex as follows: # Negative (prefix ' or preceding word ' or ) # Benefactive ' or ' # Main verb # Centripetal ' or ' # Third person present marker '''' # Pronoun prefix # Reduplication of any prior prefixes # Durative stem-initial prefix # Auxiliary verb # Tense, aspect, mood suffix # Reflexive/reciprocal suffix '''' The benefactive prefix indicates that something was done "for" somebody as, as in ', "he killed it for me". ' is used when there is a main-auxiliary distinction; ' is used when there is only one verb in the complex. The centripetal particle is used to indicate motion within the speaker’s frame of reference, with the idea of the motion coming "back" or "This way". It is the only way to distinguish the meaning of verbs "to take" from "to bring" or "to go" from "to come".

In the 1660s Newton studied the motion of colliding bodies, and deduced that the centre of mass of two colliding bodies remains in uniform motion. Surviving manuscripts of the 1660s also show Newton's interest in planetary motion and that by 1669 he had shown, for a circular case of planetary motion, that the force he called "endeavour to recede" (now called centrifugal force) had an inverse-square relation with distance from the center. After his 1679–1680 correspondence with Hooke, described below, Newton adopted the language of inward or centripetal force. According to Newton scholar J. Bruce Brackenridge, although much has been made of the change in language and difference of point of view, as between centrifugal or centripetal forces, the actual computations and proofs remained the same either way.

Though the body's speed is constant, its velocity is not constant: velocity, a vector quantity, depends on both the body's speed and its direction of travel. This changing velocity indicates the presence of an acceleration; this centripetal acceleration is of constant magnitude and directed at all times towards the axis of rotation. This acceleration is, in turn, produced by a centripetal force which is also constant in magnitude and directed towards the axis of rotation. In the case of rotation around a fixed axis of a rigid body that is not negligibly small compared to the radius of the path, each particle of the body describes a uniform circular motion with the same angular velocity, but with velocity and acceleration varying with the position with respect to the axis.

Assume the particle is oscillating in a circular path with non-zero centripetal acceleration. When the rope is cut, the particle's path changes abruptly to a straight path, and the force in the inward direction changes suddenly to zero. Imagine a monomolecular fiber cut by a laser; the particle would experience very high rates of jerk because of the extremely short cutting time.

As characterized through the work of Diane Perrons, in Anglo-American literature, the New Economy consists of two distinct types. New Economic Geography 1 (NEG1) is characterized by sophisticated spatial modelling. It seeks to explain uneven development and the emergence of industrial clusters. It does so through the exploration of linkages between centripetal and centrifugal forces, especially those of economies of scale.

A car driving on said track is slowly accelerated until the outermost tires on the car begin to slip. Going any faster would cause the car to drive outside the defined radius. At this point, the speed of the car is recorded, and given the centripetal acceleration formula, v²/r, a car's handling in terms of lateral gs can be derived.

The normal force is actually the sum of the radial and tangential forces. The component of weight force is responsible for the tangential force here (We have neglected frictional force). The radial force (centripetal force) is due to the change in direction of velocity as discussed earlier. In non-uniform circular motion, normal force and weight may point in the same direction.

Members of the genus Olindias have a dome-shaped bell, four radial canals and many centripetal canals. The gonads are beside the radial canals and have characteristic papilliform processes. There are a few primary tentacles growing part way down the bell with adhesive suckers and cnidocytes in bands. There are a pair of statocysts adjoining the base of each primary tentacle.

Bakhtin conceived the human dialectic as two forces analogous to the physical forces centripetal (emotional forces tending towards unity) and centrifugal (emotional forces tending towards divergence). Like the Yin and Yang, Bakhtin's forces have no ultimate resolution. Baxter took the deep structural analysis of Bakhtin and applied it to communication theory. She found a T-Bangha of axes where this dynamic tension operated.

The "Ode" has centrifugal tendencies, relying for its effects on elements of history and pottery and visual aesthetics. Cabin has centripetal tendencies, relying on syntax and lexical choice to delineate characters and establish mood. But the one veers inward, the other pushes outward. Criticism reflects these movements, centripetally focusing on the aesthetic function of literature, centrifugally on the social function of literature.

Aspidella consists of disk- shaped fossils, with concentric rings and/or centripetal rays. The diameter of circular Aspidella varies from 1 to 180 mm.Peterson. P. 131 Most individuals are between 4 and 10 mm, but smaller individuals would presumably have decayed before they could fossilize. Other Aspidella take the form of ellipses, 3–8 cm long and 1–4 cm wide.

Centripetal force causes the acceleration measured on the rotating surface of the Earth to differ from the acceleration that is measured for a free-falling body: the apparent acceleration in the rotating frame of reference is the total gravity vector minus a small vector toward the north-south axis of the Earth, corresponding to staying stationary in that frame of reference.

However, since MRI appearance is practically pathognomonic, biopsy is rarely needed for verification. On ultrasound, cavernous haemangiomas in liver appeared as homogenous, hyperechoic lesions with posterior acoustic enhancement. On CT or MRI scans, it shows peripheral globular/nodular enhancement in the arterial phase, with portions of attenuation of enhancing areas. In the portal venous phase, it shows progressive centripetal enhancement.

Here the centripetal force is the gravitational force, and the axis mentioned above is the line through the center of the central mass perpendicular to the plane of motion. In this case, not only the distance, but also the speed, angular speed, potential and kinetic energy are constant. There is no periapsis or apoapsis. This orbit has no radial version.

Theorem 4 shows that with a centripetal force inversely proportional to the square of the radius vector, the time of revolution of a body in an elliptical orbit with a given major axis is the same as it would be for the body in a circular orbit with the same diameter as that major axis. (Proposition 15 in the Principia.) A scholium points out how this enables determining the planetary ellipses and the locations of their foci by indirect measurements. Problem 4 then explores, for the case of an inverse-square law of centripetal force, how to determine the orbital ellipse for a given starting position, speed, and direction of the orbiting body. Newton points out here, that if the speed is high enough, the orbit is no longer an ellipse, but is instead a parabola or hyperbola.

As these are progressive, centripetal phenomena, each location of the light zone is overtaken by an expanding dark zone. Although initially developed along dune margins, spot formation quickly spreads onto and between dunes. As spring progresses, fan-shaped tails ('spiders') develop from the central spot. Defrosting occurs as the low albedo polar sand heats beneath an optically thin layer of frost, causing the frost to evaporate.

This awareness gave rise to chairs designed specifically for these new administrative employees: office chairs. This caught the attention of Otto von Bismarck, who is credited with popularizing the office chair by distributing them throughout parliament during his time in office. American inventor Thomas E. Warren (b. 1808), designed the Centripetal Spring Armchair in 1849 which was produced by the American Chair Company in Troy, New York.

The door would be closed and the room would begin to rotate. When the rate of rotation was sufficient, the floor would drop a few feet, leaving the riders pinned to the wall by centripetal force. On July 19, 2000, two girls, aged 11 and 13, were injured on the ride. Both girls sustained injuries to their feet; at least one had broken bones.

On automobiles, camber thrust may contribute to or subtract from the total centripetal force generated by the tire, depending on the camber angle. On a well-aligned vehicle, camber thrust from the tires on each side balances out. On a surface rough enough for one front tire to momentarily lose traction, camber thrust from the other front tire can cause the vehicle to wander or feel skittish.

TGV track construction has a few key differences from normal railway lines. The radii of curves are larger so that trains can traverse them at higher speeds without increasing the centripetal acceleration felt by passengers. The radii of LGV curves have historically been greater than : new lines have minimum radii of to allow for future increases in speed. LGVs can incorporate steeper gradients than normal.

M. marginata has a small medusa with a bell diameter of up to . It is hemispherical in shape and the gonads hang from the four distinctive radial canals. The marginal ring canal has 50 short centripetal canals branching from it with a dense marginal fringe of about 600 short trailing tentacles. This hydrozoan is opaque white with a slightly reddish tinge near the bell margin.

This process can be repeated until no visible traces of dirt or sand remain. Once drained, the greens are spun, which generates a centripetal force that drives the excess moisture, through the perforation in the central strainer, to the outer bowl. Salad spinners are considered to be an easy product to use and operate, but have been criticized for being bulky, space-consuming and difficult-to-store.

This charges the particles that subsequently travel on a drum. The conducting particles lose their charge to the drum and are removed from the drum with centripetal acceleration. Electrostatic plate separators work by passing a stream of particles past a charged anode. The conductors lose electrons to the plate and are pulled away from the other particles due to the induced attraction to the anode.

In accordance with Newton's third law of motion, the body in curved motion exerts an equal and opposite force on the other body. This reactive force is exerted by the body in curved motion on the other body that provides the centripetal force and its direction is from that other body toward the body in curved motion.

Hydristor There are several problems with the historical design. The vane tips radially contact the cam ring elliptic surface and cause a significant friction as the rotor and vanes turn. This friction is both pressure dependent and speed squared dependent due to RPM-squared centripetal forces. The speed is limited to about 6-7,000 RPM and the pressure is limited to about 2,500 PSI.

A nectar-containing disc is present on the upper surface of the carpels. Flowers consist of five petals, five stamens, and an entire calyx. Flowers change sex in their development, so the stamens release their pollen before the stigma of the same flower is receptive. The arrangement is centripetal, meaning the oldest flowers are near the edge and the youngest flowers are in the center.

The sling or pouch, which contributes to acceleration of the projectile and then releases it at the desired launch angle, is often made using polyester rope or other durable thin material. The release mechanism is a hook with a specific bend in its tip to determine when centripetal force will release one end of the sling, freeing the projectile to continue on its path.

Figure 1: An attractive force F(r) causes the blue planet to move on the cyan circle. The green planet moves three times faster and thus requires a stronger centripetal force, which is supplied by adding an attractive inverse-cube force. The red planet is stationary; the force F(r) is balanced by a repulsive inverse-cube force. A GIF version of this animation is found here.

A carousel provides rotation about a vertical axis. Many rides provide a combination of rotations about several axes. In Chair-O-Planes the rotation about the vertical axis is provided mechanically, while the rotation about the horizontal axis is due to the centripetal force. In roller coaster inversions the rotation about the horizontal axis is one or more full cycles, where inertia keeps people in their seats.

This helps attenuate resonances at the gyroscopic frequencies of journal bearings (sometimes called conical or rocking modes). It is very difficult to make a mechanical bearing which is atomically smooth and round; and mechanical bearings deform in high-speed operation due to centripetal force. In contrast, fluid bearings self-correct for minor imperfections and slight deformations. Fluid bearings are typically quieter and smoother (more consistent friction) than rolling-element bearings.

Overspeed for power plant turbines can be catastrophic, resulting in failure due to the turbines' shafts and blades being off balance and potentially throwing their blades and other metal parts at very high speeds. Different safeguards exist, which include a mechanical and electrical protection system. Mechanical overspeed protection is in the form of sensors. The system relies on the centripetal force of the shaft, a spring, and a weight.

Natural sand and recycled glass are mixed and heated to 1,450 °C, to produce glass. The fiberglass is usually produced by a method similar to making cotton candy, by forcing it through a fine mesh by centripetal force, cooling on contact with the air. Cohesion and mechanical strength are obtained by the presence of a binder that “cements” the fibers together. A drop of binder is placed at each fiber intersection.

The Bznunis are mentioned in Royal and Military letters. At the times of Khosrov Kotak, the tribe householder Databen Bznuni disobeying the centripetal authorities rebelled against the king. In Arest battle Vache Mamikonyan breaks some of the rebels and the rest escape. Afterwards, Databen Bznuni was brought to the king in chains, and according to the time punishment means he was condemned to death as a traitor, by stoning.

This process is only viable for coarse ores that have a close size distribution as the apertures can allow small particles to pass through. Sedimentation operates by passing water into a large thickener or clarifier. In these devices, the particles settle out of the slurry under the effects of gravity, or centripetal forces. These are limited by the surface chemistry of the particles and the size of the particles.

Artificial gravity (AG) is the increase or decrease of gravitational force on an object or person by artificial means. Different types of forces, including linear acceleration and centripetal force, can be used to generate this artificial gravitational force. The use of artificial gravity to counteract simulated microgravity (e.g. bed rest) on Earth has been shown to have conflicting results for the maintenance of bone, muscle, and cardiovascular systems.

Track conditions are also important. Softer ice tends to slow speeds, while harder ice tends to lead to faster times. Lugers race at speeds averaging around high banked curves while experiencing a centripetal acceleration of up to 5g. Men's Singles have their start locations near where the bobsled and skeleton competitors start at most tracks, while both the Doubles and Women's Singles competition have their starthouse located farther down the track.

Theorem 1 demonstrates that where an orbiting body is subject only to a centripetal force, it follows that a radius vector, drawn from the body to the attracting center, sweeps out equal areas in equal times (no matter how the centripetal force varies with distance). (Newton uses for this derivation – as he does in later proofs in this De Motu, as well as in many parts of the later Principia – a limit argument of infinitesimal calculus in geometric form,The content of infinitesimal calculus in the Principia was recognized, both in Newton's lifetime and later, among others by the Marquis de l'Hospital, whose 1696 book "Analyse des infiniment petits" (Infinitesimal analysis) stated in its preface, about the Principia, that 'nearly all of it is of this calculus' ('lequel est presque tout de ce calcul').

So, with a so-called "Quantitative" change, "one factor becomes preponderant as the other diminishes with accelerated velocity and is overpowered by the first, which therefore constitutes itself the sole self- subsistent Quality." The two Qualities are no longer distinct, mutually exclusive determinations, but together comprise a single whole. : EXAMPLE: Here, Hegel makes a powerful argument in favour of the explanatory powers of his speculative philosophy over those of empirical science, specifically with regards to the concepts of centripetal and centrifugal forces as they are supposed to relate the elliptical motion of celestial bodies. If, as is supposed by science, such an orbit is made up of an inverse relation of centripetal and centrifugal forces—the former predominating over the other as the body approaches perihelion, the reverse if approaching aphelion—then the sudden overtaking of the stronger force by the weaker that takes place on either end of the orbit can only be explained by some mysterious third force.

Milgrom noted that this discrepancy could be resolved if the gravitational force experienced by a star in the outer regions of a galaxy was proportional to the square of its centripetal acceleration (as opposed to the centripetal acceleration itself, as in Newton's second law), or alternatively if gravitational force came to vary inversely with radius (as opposed to the inverse square of the radius, as in Newton's law of gravity). In MOND, violation of Newton's laws occurs at extremely small accelerations, characteristic of galaxies yet far below anything typically encountered in the Solar System or on Earth. MOND is an example of a class of theories known as modified gravity, and is an alternative to the hypothesis that the dynamics of galaxies are determined by massive, invisible dark matter halos. Since Milgrom's original proposal, proponents of MOND have claimed to successfully predict a variety of galactic phenomena that they state are difficult to understand as consequences of dark matter.

Asteroid terraria are fictional space habitats described in the hard science fiction novel 2312 (2012) by Kim Stanley Robinson. In the novel, a 'terrarium' is an artificially created ecosystem in the cylindrical hollow interior of an asteroid. This hollow space is crafted with self-replicating excavators. On the inner surface of this hollow cylinder an ecosystem can thrive in artificial gravity resulting from centripetal force, produced by spinning the asteroid on its longest axis.

The RoboSeed Nano controllable monocopter UAV Monocopters, in which the entire aircraft rotates about its center of mass as it flies, present advantages and challenges as unmanned aerial vehicles (UAVs) to the designer. As highly centripetal machines, they cannot be manned. The first of these monocopters were constructed by Dr. Charles W. McCutchen and powered by reciprocating model airplane enginesMcCutchen, C.W., 1954, "Charles McCutchen's Flying Machines" Aeromodeller, 19, 222, p.350 ff.

There is a pressure gradient from the perimeter of the bowl or cup toward the center. This pressure gradient provides the centripetal force necessary for the circular motion of each parcel of water. The pressure gradient also accounts for a secondary flow of the boundary layer in the water flowing across the floor of the bowl or cup. The slower speed of the water in the boundary layer is unable to balance the pressure gradient.

Diagram of a gas centrifuge with countercurrent flow, used for separating isotopes of uranium. A gas centrifuge is a device that performs isotope separation of gases. A centrifuge relies on the principles of centripetal force accelerating molecules so that particles of different masses are physically separated in a gradient along the radius of a rotating container. A prominent use of gas centrifuges is for the separation of uranium-235 (235U) from uranium-238 (238U).

Unlike tangential acceleration, centripetal acceleration is present in both uniform and non-uniform circular motion. frameless In non- uniform circular motion, normal force does not always point in the opposite direction of weight. Here is an example with an object traveling in a straight path then loops a loop back into a straight path again. frameless This diagram shows the normal force pointing in other directions rather than opposite to the weight force.

The Meia-Lua de compasso (lit: compass half moon) aka. rabo do arria, is an attack that embodies the true element of Capoeira since it combines an evasive maneuver with a spinning kick. The transfer of power begins with the hand slamming into the ground and ending with the spin of the kicking heel. The power of the kick derives its energy from the similar centripetal force of a golf club swing.

"SAFRING Bird Ringing Manual ". As a general rule, the tail feathers are moulted and replaced starting with the innermost pair. Centripetal moults of tail feathers are however seen in the Phasianidae. The centrifugal moult is modified in the tail feathers of woodpeckers and treecreepers, in that it begins with the second innermost pair of feathers and finishes with the central pair of feathers so that the bird maintains a functional climbing tail.

On December 11, 2008, the Free Software Foundation filed suit against Cisco regarding Cisco's failure to comply with the GPL and LGPL license models and make the applicable source code publicly available. On May 20, 2009, Cisco settled this lawsuit by complying with FSF licensing terms and making a monetary contribution to the FSF. In October 2020, Cisco was ordered to pay US$1.9 billion to Centripetal Networks for infringement on four cybersecurity patents.

When spheroids are in contact their inner zones may be distinct while the outer ones are common to both individuals having the outlines of a figure of eight. This proves that growth was centrifugal, not centripetal. Many varieties of spheroids are described presenting great differences in composition and in structure. Some are merely rounded balls consisting of the earliest minerals of the rock, such as apatite, zircon, biotite and hornblende, and possessing no regular arrangement.

This gene encodes the largest subunit of dynactin, a macromolecular complex consisting of 23 subunits (11 individual proteins ranging in size from 22 to 150 kD). Dynactin binds to cytoplasmic dynein, dynein cargo adaptors, and microtubules. It is involved in a diverse array of cellular functions, including ER-to-Golgi transport, the centripetal movement of lysosomes and endosomes, spindle formation, chromosome movement, nuclear positioning, and axonogenesis. This subunit is commonly referred to p150-glued.

Left-sided and bilateral chylothoraces are less common and occur in 33% and 17% of cases, respectively. In the case of cancer, invasion into the thoracic duct or collateral lymph channels can obstruct lymph. In the case of mediastinal lymphadenopathy, the enlarged lymph node causes compression of the lymphatic channels and thoracic duct. This impedes the centripetal drainage of the flow of lymph from the edges of the lung parenchyma and pleural surfaces.

This gene encodes a 50-kD subunit of dynactin, a macromolecular complex consisting of 23 subunits (11 individual proteins ranging in size from 22 to 150 kD). The subunit is commonly referred to as p50 or dynamitin. Dynactin binds to both microtubules and cytoplasmic dynein. It is involved in a diverse array of cellular functions, including ER-to-Golgi transport, the centripetal movement of lysosomes and endosomes, spindle formation, chromosome movement, nuclear positioning, and axonogenesis.

The kinetic energy of a rotating object depends on the mass of the object, the shape of the object, and the square of the speed of rotation. Therefore, compulsators tend to have very light rotors spinning very fast in order to store the most energy in the available mass, and because too much mass in the rotor causes problems with the magnitude of centripetal force required to prevent the rotor from flying apart.

Little or no maneuverability required, as once at speed the model's altitude is maintained by centripetal Acceleration. Racing models need to be both relatively light for good acceleration from the start, or after a pit stop, and to reduce the pitch of the airfoil required to maintain lift. Race Aircraft also be fairly strong to withstand the pit man catching the model after landing. To control the airplane, the lines must remain in tension.

It is independent of both the Earth's rotation and the direction of motion. For example, when an aeroplane carrying gravimetric reading instruments cruises over one of the poles at constant altitude, the aeroplane's trajectory follows the curvature of the earth. The first term in the formula is zero then, due to the cosine of the angle being zero, and the second term then represents the centripetal acceleration to follow the curvature of the Earth's surface.

KITE Launcher — transferring momentum to the vehicle. An endo-atmospheric tether uses the long cable within the atmosphere to provide some or all of the velocity needed to reach orbit. The tether is used to transfer kinetics (energy and momentum) from a massive, slow end (typically a large subsonic or low supersonic aircraft) to a hypersonic end through aerodynamics or centripetal action. The Kinetics Interchange TEther (KITE) Launcher is one proposed endo-atmospheric tether.

However, a faster high jumper might need about 13 strides. A greater run speed allows a greater part of the body's forward momentum to be converted upward. The J type approach, favored by Fosbury floppers, allows for horizontal speed, the ability to turn in the air (centripetal force), and good take-off position. This allows for horizontal momentum to turn into vertical momentum, propelling the jumper off the ground and over the bar.

Space stations in science fiction can employ both existing and speculative technologies. One of the earliest images was the rotating wheel space station (such as the Stanford torus), the inertia and centripetal force of which would theoretically simulate the effects of gravity. Stations using artificial gravity are still purely speculative. Space stations allow characters a relatively constrained setting, serving either as plot site or as safe refuge to which one can retreat.

Water megamasers may be used to provide accurate distance determinations to distant galaxies. Assuming a Keplerian orbit, measuring the centripetal acceleration and velocity of water maser spots yields the physical diameter subtended by the maser spots. By then comparing the physical radius to the angular diameter measured on the sky, the distance to the maser may be determined. This method is effective with water megamasers because they occur in a small region around an AGN, and have narrow linewidths.

Beta-centractin is a protein that in humans is encoded by the ACTR1B gene. This gene encodes a 42.3 kD subunit of dynactin, a macromolecular complex consisting of 10 subunits ranging in size from 22 to 150 kD. Dynactin binds to both microtubules and cytoplasmic dynein. It is involved in a diverse array of cellular functions, including ER-to-Golgi transport, the centripetal movement of lysosomes and endosomes, spindle formation, chromosome movement, nuclear positioning, and axonogenesis.

The St. James' Church, who owns the cemetery, is the oldest place of worship for the Christian community of Delhi. The church along with cemetery, St. Stephen's hostel, and the Victorian era houses of Kashmere Gate neighbourhood were once considered to be "centripetal" part of Christians in Delhi. According to the Indian Paranormal Society the headless apparition of John Nicholson haunts the place. There are also other speculations that the ghosts of Europeans haunt the place.

One of the original public stunts done on a motorcycle was riding the Globe of Death. In this stunt, one or more riders enter a steel banded sphere through a trap door and begin circling. The centripetal force of accelerating along the curve allows the rider to eventually circle on any plane inside the sphere, including sideways and upside-down. Though this is one of the original stunts, it is still commonly seen among circus acts.

Thirakalkkapuram opens with the life story of a motherless child, Seethamma, who is also believed to be the centripetal force of curses since her birth. She is looked after by her mother's sister and husband (Moothar) who do not have kids themselves. Seethamma's mom is believed to have died because she eloped against the rules of the Ocean and the community. Chengan is the male protagonist, projected as a gullible young fisherman with a mother who hates his attitude.

Capillary haemangiomas in the liver are found in 16% of all liver haemangiomas. Its sizes are usually less than 1 to 2 cm in diameter. It may show a "flash- filling" phenomenon in which there is the fast enhancement of the contrast material in the lesion instead of slow, centripetal, nodular filling of the lesions in usual haemangiomas. On CT and MRI, it shows rapid filling during arterial phase, with contrast retention in venous and delayed phases.

At the same time the inner layer exerts an elastic centripetal force on the middle layer, while and the outer layer exerts an elastic centrifugal force, which results in an internal stress. It is the stresses in the blade and their causes that mainly interest mechanical engineers in this situation. A two-shoe centrifugal clutch. The motor spins the input shaft that makes the shoes go around, and the outer drum (removed) turns the output power shaft.

Both forces can point down, yet the object will remain in a circular path without falling straight down. First let's see why normal force can point down in the first place. In the first diagram, let's say the object is a person sitting inside a plane, the two forces point down only when it reaches the top of the circle. The reason for this is that the normal force is the sum of the tangential force and centripetal force.

Desiccation cracks in sludge Centripetal desiccation cracks in the Lower Jurassic Moenave Formation at the St. George Dinosaur Discovery Site at Johnson Farm, southwestern Utah. A dinosaur footprint is at center. Desiccation (from Latin de- "thorougly" + siccare "to dry") is the state of extreme dryness, or the process of extreme drying. A desiccant is a hygroscopic (attracts and holds water) substance that induces or sustains such a state in its local vicinity in a moderately sealed container.

Spokey Dokeys (sometimes Spokey Dokies, Spokey Dokes, or known generically as spoke beads) are a bicycle accessory, originating in the 1980s, most popular with children. They are plastic beads that attach onto bicycle wheel spokes. When the bicycle user pedals at a slow speed, the beads slide up and down the spoke, resulting in noise. When speed is increased the beads move to the outside of the rim due to centripetal force and cease to make sound.

The symmetric centripetal actin flow is the basis of formation of the p-SNAP ring. The accumulation and polarization of actin is triggered by TCR/CD3 interactions with integrins and small GTPases (such as Rac1 or Cdc42). These interactions activate large multi-molecular complexes (containing WAVE (Scar), HSP300, ABL2, SRA1, and NAP1 and others) to associate with Arp2/3, which directly promotes actin polymerization. As actin is accumulated and reorganized, it promotes clustering of TCRs and integrins.

The term r\dot\varphi^2 is sometimes referred to as the centripetal acceleration, and the term 2\dot r \dot\varphi as the Coriolis acceleration. For example, see Shankar. Note: these terms, that appear when acceleration is expressed in polar coordinates, are a mathematical consequence of differentiation; they appear whenever polar coordinates are used. In planar particle dynamics these accelerations appear when setting up Newton's second law of motion in a rotating frame of reference.

Some of the reasons that artificial gravity remains unused today in spaceflight trace back to the problems inherent in implementation. One of the realistic methods of creating artificial gravity is a centripetal force pulling a person towards a relative floor. In that model, however, issues arise in the size of the spacecraft. As expressed by John Page and Matthew Francis, the smaller a spacecraft (the shorter the radius of rotation), the more rapid the rotation that is required.

Schematic of directional solidification Directional solidification uses a thermal gradient to promote nucleation of metal grains on a low temperature surface, as well as to promote their growth along the temperature gradient. This leads to grains elongated along the temperature gradient, and significantly greater creep resistance parallel to the long grain direction. In polycrystalline turbine blades, directional solidification is used to orient the grains parallel to the centripetal force. It is also known as dendritic solidification.

When a vehicle (motor vehicle or railroad train) goes around a curve, rolling resistance usually increases. If the curve is not banked so as to exactly counter the centrifugal force with an equal and opposing centripetal force due to the banking, then there will be a net unbalanced sideways force on the vehicle. This will result in increased rolling resistance. Banking is also known as "superelevation" or "cant" (not to be confused with rail cant of a rail).

Figure 2: Two spheres tied with a string and rotating at an angular rate ω. Because of the rotation, the string tying the spheres together is under tension. Figure 3: Exploded view of rotating spheres in an inertial frame of reference showing the centripetal forces on the spheres provided by the tension in the tying string. Inertial and non-inertial reference frames can be distinguished by the absence or presence of fictitious forces, as explained shortly.

Eden (Abduction of Eden) is a 2012 American drama film about human trafficking. It was directed by Megan Griffiths, who co-wrote the screenplay with Richard B. Phillips and stars Jamie Chung, Matt O'Leary and Beau Bridges. The film was produced by Colin Harper Plank and Jacob Mosler through Plank's Centripetal Films production company. It was inspired by the story of Chong Kim, who claims that she was kidnapped and sold into a domestic human trafficking ring in the mid 1990s.

The lake was fed by a centripetal pattern of streams and by groundwater, with highstands being fed mainly by streams and lowstands by groundwater. The Manzano Mountains were its main water source. The total watershed of Lake Estancia had an area of about , about 22% of which were occupied by the lake during the late Wisconsin glaciation. This is a large proportion of the watershed, a consequence of the high elevation of Lake Estancia which resulted in lower temperatures and thus slower evaporation.

In a normal turn, rear wheels follow the front ones because resistance to motion in the forward direction (in which the wheels turn) is significantly less than in the sideways direction. The latter provides the centripetal force that makes the rear end of the car follow the turn. When the driver locks the rear wheels with the handbrake, both directions offer the same resistance, so the rear end tends to keep moving in the existing direction (due to inertia) and thus slides out.

Spermatogenesis takes place within several structures of the male reproductive system. The initial stages occur within the testes and progress to the epididymis where the developing gametes mature and are stored until ejaculation. The seminiferous tubules of the testes are the starting point for the process, where spermatogonial stem cells adjacent to the inner tubule wall divide in a centripetal direction--beginning at the walls and proceeding into the innermost part, or lumen--to produce immature sperm. Maturation occurs in the epididymis.

Book 1, subtitled De motu corporum (On the motion of bodies) concerns motion in the absence of any resisting medium. It opens with a mathematical exposition of "the method of first and last ratios", a geometrical form of infinitesimal calculus. Newton's proof of Kepler's second law, as described in the book. If a continuous centripetal force (red arrow) is considered on the planet during its orbit, the area of the triangles defined by the path of the planet will be the same.

The Arch rises in a park formed by Piazza della Liberta; the arch is just centripetal to the now detached Porta San Gallo, once the main northern gate of the city. The park is located in an island surrounded by a series of homogenous porticoed palaces, designed by Giuseppe Poggi in the 19th century, who also landscaped the park.Florence: A Walking Guide to Its Architecture, by Richard J.

After World War I, automatic propellers were developed to maintain an optimum angle of attack. This was done by balancing the centripetal twisting moment on the blades and a set of counterweights against a spring and the aerodynamic forces on the blade. Automatic props had the advantage of being simple, lightweight, and requiring no external control, but a particular propeller's performance was difficult to match with that of the aircraft's power plant. The most common variable pitch propeller is the constant-speed propeller.

Successive curves in the same direction are sometimes called progressive curves and successive curves in opposite directions are called reverse curves. The Euler spiral provides the shortest transition subject to a given limit on the rate of change of the track superelevation (i.e. the twist of the track). However, as has been recognized for a long time, it has undesirable dynamic characteristics due to the large (conceptually infinite) roll acceleration and rate of change of centripetal acceleration at each end.

The Meteorite in action at Worden Park Round Up is an amusement ride consisting of a circular horizontal platform with a vertical cage-like wall around the edge. The platform is attached to a motor on a hydraulic arm. The ride starts out by spinning until the centripetal force is enough to push riders against the wall. Then the arm raises the horizontal platform to a vertical position in which riders, instead of spinning horizontally, are now spinning almost vertically.

Structural engineers, however, felt that the re-engineered steel sheet pilings would give way under the centripetal forces placed on it by the quicksand as well as the building's weight. This required them to alter their plan for the wall columns that supported the building's frame and upper floors. The new foundation's wall columns (now called "fulcrums") were set inward from the sub-basement wall. Each fulcrum consisted of two C-beams, each wide and held together by four cover plates.

This occurs because centripetal acceleration from the orbital motion resists the gravitational pull of the star only in the radial direction, but the cloud remains free to collapse in the vertical direction. The outcome is the formation of a thin disc supported by gas pressure in the vertical direction. The initial collapse takes about 100,000 years. After that time the star reaches a surface temperature similar to that of a main sequence star of the same mass and becomes visible.

After the exchanges with Hooke, Newton worked out proof that the elliptical form of planetary orbits would result from a centripetal force inversely proportional to the square of the radius vector. Newton communicated his results to Edmond Halley and to the Royal Society in De motu corporum in gyrum, a tract written on about nine sheets which was copied into the Royal Society's Register Book in December 1684.Whiteside, D.T., ed. (1974). Mathematical Papers of Isaac Newton, 1684–1691. 6.

The bottle flip is often combined with the Dab after a successful flip. The complex physics behind the activity incorporates concepts of fluid dynamics, projectile motion, angular momentum, centripetal force, and gravity. In 2018, a group of students and professors from the Netherlands developed a minimal model of the water bottle flip involving conservation of angular momentum and, most importantly, the redistribution of mass along the bottle. The model estimates that the best filling fractions for water flipping lie in the range between 20% and 40%.

In the physics-based gameplay, the player swings large melee weapons and relies on centripetal force to give the object enough kinetic energy to destroy enemies. The demo release had six main types of weapons - four melee and two ranged. The different weapon types offer a certain variety. To be a slow, but well-armored powerhouse using hammers or maces to deliver slow, but crushing blows, or a nimble, but poorly protected sword-wielder, delivering quick, but weak attacks, is entirely up to the player.

Gravity measurements are a reflection of the earth's gravitational attraction, its centripetal force, tidal accelerations due to the sun, moon, and planets, and other applied forces. Gravity gradiometers measure the spatial derivatives of the gravity vector. The most frequently used and intuitive component is the vertical gravity gradient, Gzz, which represents the rate of change of vertical gravity (gz) with height (z). It can be deduced by differencing the value of gravity at two points separated by a small vertical distance, l, and dividing by this distance.

Such a station would rotate about its axis, thus creating an environment of artificial gravity. Occupants of the station would experience centripetal acceleration, according to the following equation: : a = -\omega^2 r where \omega is the angular velocity of the station, r is its radius, and a is linear acceleration at any point along its perimeter. In theory, the station could be configured to simulate the gravitational acceleration of Earth (9.81 m/s2), allowing for human long stays in space without the drawbacks of microgravity.

Overall drivetrain reduction comes down to three basic factors: transmission gearing (including overdrive), differential gearing (in the axle), and tire size. The rotation speed problem comes into effect when the differential gearing is a high ratio and an overdrive is used to compensate. This may create unpleasant vibrations at high speeds and possible destruction of the driveshaft due to the centripetal forces or uneven balance. The driveshaft is usually a hollow metal tube that requires balancing to reduce vibration and contains no internal bracing.

These stars, if they exist, are thought to start from a neutron star with a mass that would cause it to collapse into a black hole if it were not rapidly spinning. Instead, the neutron star spins fast enough so that its centripetal force overcomes gravity. This makes the neutron star a typical but doomed pulsar whose strong magnetic field radiates energy away and slows its spin. Eventually the weakening centrifugal force is no longer able to stop the pulsar from its transformation into a black hole.

The centrifuge relies on the force resulting from centripetal acceleration to separate molecules according to their mass, and can be applied to most fluids.Basics of Centrifuge - Cole Parmer The dense (heavier) molecules move towards the wall and the lighter ones remain close to the center. The centrifuge consists of a rigid body rotor rotating at full period at high speed. Concentric gas tubes located on the axis of the rotor are used to introduce feed gas into the rotor and extract the heavier and lighter separated streams.
|
|
The motor spins the rotor, creating the centripetal force on the components as they enter the cylindrical rotor. This force acts to separate the molecules of the gas, with heavier molecules moving towards the wall of the rotor, and the lighter molecules towards the central axis. There are two output lines, one for the fraction enriched in the desired isotope (in uranium separation, this is U-235), and one depleted in it. The output lines take these separations to other centrifuges to continue the centrifugation process.

A geocentric orbit or Earth orbit involves any object orbiting the Earth, such as the Moon or artificial satellites. In 1997 NASA estimated there were approximately 2,465 artificial satellite payloads orbiting the Earth and 6,216 pieces of space debris as tracked by the Goddard Space Flight Center. Over 16,291 previously launched objects have decayed into the Earth's atmosphere. A spacecraft enters orbit when its centripetal acceleration due to gravity is less than or equal to the centrifugal acceleration due to the horizontal component of its velocity.

They also involved the combination of tangential and radial displacements, which Newton was making in the 1660s. The difference between the centrifugal and centripetal points of view, though a significant change of perspective, did not change the analysis.See J. Bruce Brackenridge, "The key to Newton's dynamics: the Kepler problem and the Principia", (University of California Press, 1995), especially at pages 20–21. Newton also clearly expressed the concept of linear inertia in the 1660s: for this Newton was indebted to Descartes' work published 1644.

Ommaya’s centripetal theory identified that the effects always begin at the surface of the brain in mild injury and extend inward to affect the diencephalic- mesencephalic core in more severe injury. His work showed that both translational and rotational acceleration produce focal lesions but that only rotational acceleration produced diffuse axonal injury. When damage is found in the rostral brainstem it is also associated with diffuse hemispheric damage. Prior to his work it was believed that the mechanism of concussion was linked to primary brainstem injury.

This skier is in the middle of a high- performance turn during a slalom race. The arced shape of the ski can be seen, especially on the outside ski (right side of the image). When making a carving turn, a skier is skiing in dynamic equilibrium, so to balance the centripetal force the skier brings their center of mass to the inside of the turn. This is like a cyclist leaning to the inside of a turn to avoid being thrown off of their bicycle.

Celestial bodies rotating about each other often have elliptic orbits. The special case of circular orbits is an example of a rotation around a fixed axis: this axis is the line through the center of mass perpendicular to the plane of motion. The centripetal force is provided by gravity, see also two-body problem. This usually also applies for a spinning celestial body, so it need not be solid to keep together unless the angular speed is too high in relation to its density.

Coalescence occurs when droplets bump into each other and combine to form a larger droplet, so the average droplet size increases over time. Emulsions can also undergo creaming, where the droplets rise to the top of the emulsion under the influence of buoyancy, or under the influence of the centripetal force induced when a centrifuge is used. Creaming is a common phenomenon in dairy and non-dairy beverages (i.e. milk, coffee milk, almond milk, soy milk) and usually does not change the droplet size.
|
|
The term has sometimes also been used for the reactive centrifugal force that may be viewed as a reaction to a centripetal force in some circumstances. In the inertial frame of reference (upper part of the picture), the black ball moves in a straight line. However, the observer (brown dot) who is standing in the rotating/non-inertial frame of reference (lower part of the picture) sees the object as following a curved path due to the Coriolis and centrifugal forces present in this frame.

In the case of an aircraft making a turn, the force causing centripetal acceleration is the horizontal component of the lift acting on the aircraft. In straight, level flight, the lift acting on the aircraft acts vertically upwards to counteract the weight of the aircraft which acts downwards. During a balanced turn where the angle of bank is θ the lift acts at an angle θ away from the vertical. It is useful to resolve the lift into a vertical component and a horizontal component.

This gene encodes a 42.6 kD subunit of dynactin, a macromolecular complex consisting of 10-11 subunits ranging in size from 22 to 150 kD. Dynactin binds to both microtubules and cytoplasmic dynein. It is involved in a diverse array of cellular functions, including ER-to-Golgi transport, the centripetal movement of lysosomes and endosomes, spindle formation, chromosome movement, nuclear positioning, and axonogenesis. This subunit is present in 8-13 copies per dynactin molecule, and is the most abundant molecule in the dynactin complex.

The technique starts with the user standing up or semi-crouched in the position of ginga. By twisting his body towards one side and downing one or both hands onto the ground for balance, he launches the opposite leg into the air in a semi-circular movement that ends with his heel striking the opponent, usually in the head, or completing the spin into another ginga position. The power of the kick derives its energy from the similar centripetal force of a golf club swing.

The calculation for this assumes a constant train speed on a constant radius curve. When the speed of the train and the amount of cant are in balance (centrifugal matches centripetal), it is called equilibrium. This would make the components of wheel to rail force normal to the plane of the track having the same in aggregate for the outside rail as for the inside rail. This would also make the passengers in the train not to perceive any lateral acceleration (a push toward sideway).

The verbal morphology is less complicated than for other early-attested Indo-European languages like Ancient Greek and Sanskrit. Hittite verbs inflect according to two general conjugations (mi-conjugation and hi-conjugation), two voices (active and medio-passive), two moods (indicative mood and imperative) and two tenses (present, and preterite). Verbs have two infinitive forms, a verbal noun, a supine, and a participle. Rose (2006) lists 132 hi verbs and interprets the hi/mi oppositions as vestiges of a system of grammatical voice ("centripetal voice" vs.

The phylogenetic signature of this model is that the central population becomes derived, while the peripheral isolates stay pleisomorphic—the reverse of the general model. In contrast to centrifugal speciation, peripatric speciation has sometimes been referred to as centripetal speciation (see figures 1 and 2 for a contrast). Centrifugal speciation has been largely ignored in the scientific literature, often dominated by the traditional model of peripatric speciation. Despite this, Brown cited a wealth of evidence to support his model, of which has not yet been refuted.

This separation processes usually incorporate centripetal pump at effluent discharge point to minimise foaming and contact with air. :Due to its ability to operate in discontinuous mode, chamber bowl is one of suitable option for batch processing. Also the classification of solids separated from feed is effective with chamber bowl as increasing in centrifugal force exerting on the slurry as it pass from middle chamber towards out. :In terms of maintenance, unlike peeler centrifuge designs, the machine has to shut down completely to remove chambers from casing.

The motion depicted in the animation is for the idealized situation that the force exerted by the spring increases linearly with the distance to the center of rotation. Also, the animation depicts what would occur if there would not be any friction. In rotational-vibrational coupling there is an oscillation of the angular velocity. In pulling the circling masses closer to the center of rotation, the force exerted by the spring (a centripetal force) is doing work, converting stored strain energy in the spring into kinetic energy of the masses.

An articulated bus is a long vehicle and usually requires a specially trained driver, as maneuvering (particularly reversing) can be difficult. The trailer section of a "puller" bus can be subject to unusual centripetal forces, which many people can find uncomfortable, although this is not an issue with "pushers". Nonetheless, the articulated bus is highly successful in Budapest, Hungary, where the BKV city transit company has been operating more than 1000 of them every day since the early 1970s. The Hungarian company Volán also runs hundreds of articulated buses on intercity lines.

Using yaw alone is not a very efficient way of executing a level turn in an aircraft and will result in some sideslip. A precise combination of bank and lift must be generated to cause the required centripetal forces without producing a sideslip. Pitch is controlled by the rear part of the tailplane's horizontal stabilizer being hinged to create an elevator. By moving the elevator control backwards the pilot moves the elevator up (a position of negative camber) and the downwards force on the horizontal tail is increased.

The 799 cc engine, originally designed by Ezio Mascheroni and first fitted to the F3, uses a DOHC inline three-cylinder layout with four valves per cylinder. A counter-rotating (reverse) crankshaft is used, which counteracts the centripetal forces of the wheels allowing the bike to turn faster. The bore and stroke are 79 mm and 54.3 mm. Modified to meet the Euro4 European emission standards and tuned to produce 150 bhp (110 kW) at 12.800 rpm, the engine is the most powerful triple in the MV range.

The theory of gravity allowed scientists to rapidly construct a plausible heliocentric model for the Solar System. In his Principia, Newton explained his theory of how gravity, previously thought to be a mysterious, unexplained occult force, directed the movements of celestial bodies, and kept our Solar System in working order. His descriptions of centripetal force were a breakthrough in scientific thought, using the newly developed mathematical discipline of differential calculus, finally replacing the previous schools of scientific thought, which had been dominated by Aristotle and Ptolemy. However, the process was gradual.

Another advanced diabolo style is vertax (vertical axis; also known as "Excalibur"). This is where the diabolo is "turned vertically" by means of "whipping" and is continually spun in this upright state. The person spinning it needs to rotate their body to keep up with the constant whipping action due to the momentum and centripetal motion at which the diabolo spins. Although the number of tricks seems limited, people are finding more ways to perform with this style, including vertax genocides, infinite suicides, and many suns, orbits, and satellites.

Thus, from identity we derive duality, and from both together we obtain polarity, synthesis, indifference, predominance. (Biographia Literaria) :To make it adequate, we must substitute the idea of positive production for that of rest, or mere neutralization. To the fancy alone it is the null-point, or zero, but to the reason it is the punctum saliens, and the power itself in its eminence. Matter, for Coleridge is the product of the dynamic forces - repulsion (centrifugal), and attraction (centripetal); it is not itself a productive power but a resultant.

Now assume a point particle moves with constant speed along this path, so its tangential acceleration is zero. The centripetal acceleration given by v^2/r is normal to the arc and inward. When the particle passes the connection of pieces, it experiences a jump-discontinuity in acceleration given by v^2/r, and it undergoes a jerk that can be modeled by a Dirac delta, scaled to the jump-discontinuity. For a more tangible example of discontinuous acceleration, consider an ideal spring-mass system with the mass oscillating on an idealized surface with friction.

Even though the reactive centrifugal is rarely used in analyses in the physics literature, the concept is applied within some mechanical engineering concepts. An example of this kind of engineering concept is an analysis of the stresses within a rapidly rotating turbine blade. The blade can be treated as a stack of layers going from the axis out to the edge of the blade. Each layer exerts an outward (centrifugal) force on the immediately adjacent, radially inward layer and an inward (centripetal) force on the immediately adjacent, radially outward layer.

Cradling is when a player moves their wrists and arms in a semi-circular motion to keep the ball in the pocket of the stick's head using centripetal force. The head of the lacrosse stick has a mesh or leather net strung into it that allows the player to hold the ball. Defensively, the object is to keep the opposing team from scoring and to dispossess them of the ball through the use of stick checking and body positioning. The rules of women's lacrosse are different from the men's lacrosse game.

In order to achieve a forward straight line motion, the ballbot has to lean forward to accelerate and lean backward to decelerate. Further, the ballbot has to lean into curves in order to compensate for centripetal forces, which results in elegant and graceful motions. Unlike two- wheeled balancing mobile robots like Segway that balance in one direction but cannot move in the lateral direction, the ballbot is omni-directional and hence, can roll in any direction. It has no minimal turning radius and does not have to yaw in order to change direction.

This creates a centrifugal force, that accelerates as it moves down the tapered cone. The centripetal and centrifugal forces separate the heavier water component to the outside of the vortex while the lighter oil droplets are forced to the centre. The separated oils are removed through an orifice at the inlet end of the cone and treated water is discharged through the opposite end. The centrifugal forces generated inside the vortex of the better de- oiling hydrocyclone separators are of the order of 1,000 times the force of gravity.

Two bodies similar to the Sun and Earth, i.e. with an extreme difference in mass – the red X marks the barycenter The Earth, among other planets, orbits the Sun because the Sun exerts a gravitational pull that acts as a centripetal force, holding the Earth to it, which would otherwise go shooting off into space. If the Sun's pull is considered an action, then Earth simultaneously exerts a reaction as a gravitational pull on the Sun. Earth's pull has the same amplitude as the Sun but in the opposite direction.

Mechanical overspeed systems on turbines rely on an equilibrium between the centripetal force of the rotating shaft imparted on a weight attached to the end of a turbine blade. At the specified trip point, this weight makes physical contact with a lever that releases the trip oil header, which directly moves a trip bolt and/or a hydraulic circuit to activate stop valves to close. Because the contact with the lever occurs over a relatively limited angle, there is a maximum trip response time of 15 ms (i.e. 0.015 sec).

The liquid cooled 800 cc engine, which was originally designed by Ezio Mascheroni for use in the MV Agusta F3, is the larger of the two "triples" produced by MV at this time. The engine has a counter rotating crankshaft, normally only found on GP machines, which counteracts the centripetal forces of the wheels allowing the bike to turn faster. A specific version of the engine has been produced for the Stradale. Bore and stroke dimensions of 79 mm and 54.3 mm are retained, as are the compression ratio and valve sizes.

Lap bar restraints consist of a padded bar mounted to the floor or side of the train that swings backwards into the rider's lap. These restraints are usually found on roller coasters that lack inversions. Some inverting roller coasters, notably ones created by Anton Schwarzkopf safely operate without the need for shoulder restraints. Historically, inverting roller coasters with lap bars could only perform vertical loops, as the higher centripetal force (and low lateral force) exerted while traversing a simple clothoid loop helps to keep riders safely in the train.

Fei is also known for his influential theory on ethnic groups in Chinese history, which follows the tradition of Lewis H. Morgan's stage- developmental evolutionism. A representative example of his work is Fei's 1988 Tanner lecture in Hong Kong, "Plurality and Unity in the Configuration of the Chinese Nationality." According to Fei, the Huaxia became a true ethnic group, the Han, during the Qin Dynasty. Afterwards, the Han became "a nucleus with centripetal force" with their stable agricultural society attracting and assimilating ethnic nomads from China's northern frontier such as the Qiang.

When an electron is moving through a magnetic field, it is subject to the Lorentz force that acts perpendicularly to the plane defined by the magnetic field and the electron velocity. This centripetal force causes the electron to follow a helical trajectory through the field at a radius called the gyroradius. The acceleration from this curving motion induces the electron to radiate energy in the form of synchrotron radiation. The energy emission in turn causes a recoil of the electron, known as the Abraham–Lorentz–Dirac Force, which creates a friction that slows the electron.

A Zabel engined outfit Sidecarcross is carried out in the same way as regular motocross on broadly similar tracks. Just as with road outfits, the handling of sidecars is very different from solos, as the driver cannot lean the outfit in the turns to counter the centripetal forces. Instead, to ensure the outfit does not flip over, the passenger must lean out from the sidecar as much as possible in corners. The passenger (sometimes known as the "monkey") moves his whole body around continuously, and plays a much more physical role than the sedentary driver.

Douglas DC-3 banking to make a left turn. When a fixed-wing aircraft is making a turn (changing its direction) the aircraft must roll to a banked position so that its wings are angled towards the desired direction of the turn. When the turn has been completed the aircraft must roll back to the wings-level position in order to resume straight flight. When any moving vehicle is making a turn, it is necessary for the forces acting on the vehicle to add up to a net inward force, to cause centripetal acceleration.

The Turismo Veloce (Italian for Fast Touring) is advertised as a "The Tourer With A Racing Spirit", being a sports bike built into touring bodywork. It is aimed at the same sport touring market as the Ducati Multistrada and Kawasaki Ninja 1000. Originally designed by Ezio Mascheroni, the three cylinder, 4 stroke, 12 valve, DOHC engine is derived from unit in the MV Agusta F3 800. The engine has a counter rotating crankshaft, normally only found on GP machines, which counteracts the centripetal forces of the wheels allowing the bike to turn faster.

Their dendrites branch out radiantly from a soma, and there is a significant dendritic overlap. Optical measurements of Ca2+ concentration showed that they respond strongly to the centrifugal motion (the outward motion from the soma to the dendrites), while they don't respond well to the centripetal motion (the inward motion from the dendritic tips to the soma). When the starburst cells were ablated with toxins, direction selectivity was eliminated. Moreover, their release of neurotransmitters itself, specifically calcium ions, reflect direction selectivity, which may be presumably attributed to the synaptic pattern.

If the Coriolis parameter is large, the effect of the earth's rotation on the body is significant since it will need a larger angular frequency to stay in equilibrium with the Coriolis forces. Alternatively, if the Coriolis parameter is small, the effect of the earth's rotation is small since only a small fraction of the centripetal force on the body is canceled by the Coriolis force. Thus the magnitude of f strongly affects the relevant dynamics contributing to the body's motion. These considerations are captured in the nondimensionalized Rossby number.

In 1644, René Descartes proposed that no empty space can exist and that a continuum of matter causes every motion to be curvilinear. Thus, centrifugal force thrusts relatively light matter away from the central vortices of celestial bodies, lowering density locally and thereby creating centripetal pressure. Utilizing aspects of this theory, between 1669 and 1690, Christiaan Huygens designed a mathematical vortex model. In one of his proofs, he shows that the distance elapsed by an object dropped from a spinning wheel will increase proportionally to the square of the wheel's rotation time.

When expanded, badenya is a uniting, community-oriented force; it promotes stasis and security. Just as badenya is used to mean mother-childness or sibling-hood, it is also used to mean harmony. It “connotes devotion to home, family and tradition” and “conveys a sense of community, social solidarity, and shared intimacy”. Within the community, badenya represents the “centripetal forces of society: submission to authority, stability, cooperation”. The “strong forces in Mande society [which] emphasize group norms, decisions and success over those of the individual…are reflected in the term badenya.

A roller coaster is a machine that uses gravity and inertia to send a train of cars along a winding track. The combination of gravity and inertia, along with g-forces and centripetal acceleration give the body certain sensations as the coaster moves up, down, and around the track. The forces experienced by the rider are constantly changing, leading to feelings of joy in some riders and nausea in others. The basic principles of roller coaster mechanics have been known since 1865,, and since then roller coasters have become a popular diversion.

He disliked Nissim from Ronetti Roman's Manasse, but favored the titular character for his "equilibrium". In Davila's Vlaicu Vodă, he saw the triumph of a centripetal external progress that has no time to await a slow, internal, centrifugal one. He tolerated plays by Haralamb Lecca, Grigore Ventura and others, but only in order to encourage the domestic repertoire. A promoter of Radu D. Rosetti's poetry, he admired the "objective" lyricism of the "classic" and "definitive" Ștefan Octavian Iosif, and was enraptured by Alexandru Vlahuță's România pitorească for its "triumph of reason over the feeble areas of sensibility".

Then the sum of the centrifugal and centripetal forces is to linear order in x\ . With our x axis pointing radial outward from the unperturbed location of the fluid element and our y axis pointing in the direction of increasing azimuthal angle (the direction of the unperturbed orbit), the x and y equations of motion for a small departure from a circular orbit R=R_0 are: where f_x and f_y are the forces per unit mass in the x and y directions, and a dot indicates a time derivative (i.e., \dot x is the x velocity, \ddot x is the x acceleration, etc.).

In contrast to an Oldowan tool, which is the result of a fortuitous and probably ex tempore operation to obtain one sharp edge on a stone, an Acheulean tool is a planned result of a manufacturing process. The manufacturer begins with a blank, either a larger stone or a slab knocked off a larger rock. From this blank he or she removes large flakes, to be used as cores. Standing a core on edge on an anvil stone, he or she hits the exposed edge with centripetal blows of a hard hammer to roughly shape the implement.

In this way, a dense bait ball forms as each fish scrambles to get away from the surface of the ball and hide in the interior. The symmetry of this centripetal action forms a sphere, the shape with the minimum surface area for a given volume, thereby exposing the fewest fish on the surface to the predators.Hamilton WD (1971) "Geometry for the selfish herd" Journal of Theoretical Biology 31: 295–311. The movement, sound and smell can attract more predators, including different predator species, until there is a carousel of them, each species using its own characteristic predatory strategies.

When assessing the balance between centrifugal and centripetal factors most scholars are very cautious when offering a verdict whether Czechoslovakism was doomed to fail or whether it stood a chance of success.a highly skeptical opinion in Bakke 1999, similar view in Ficeri 2017; for rather critical assessment of this theory see Peter Haslinger, Doomed to Failure?

This is true for any fixed time interval. When the interval tends to zero, the force can be considered instantaneous. (Click image for a detailed description). The second section establishes relationships between centripetal forces and the law of areas now known as Kepler's second law (Propositions 1–3), and relates circular velocity and radius of path-curvature to radial forceThis relationship between circular curvature, speed and radial force, now often known as Huygens' formula, was independently found by Newton (in the 1660s) and by Huygens in the 1650s: the conclusion was published (without proof) by Huygens in 1673.

The tangential force is zero at the top (as no work is performed when the motion is perpendicular to the direction of force applied. Here weight force is perpendicular to the direction of motion of the object at the top of the circle) and centripetal force points down, thus normal force will point down as well. From a logical standpoint, a person who is travelling in the plane will be upside down at the top of the circle. At that moment, the person's seat is actually pushing down on the person, which is the normal force.

The foremost information that the VRI provides on vibration energy, is how lung sounds behave and function during inspiration and expiration, which also includes individual breathing intensity (or vibration energy) graphs for each lung along the time period of 12 seconds. The distribution pattern of normal lung vibration energy for healthy individuals evolves centrally (presumably reflecting early airflow distribution in central large airways) and develops centrifugally in a simultaneous fashion for left and right lungs. Following peak inspiration, there is centripetal regression of vibration energy toward the end of inspiration. The same pattern is repeated during expiration phase accordingly.

This model was the first theory of gravitation which was worked out mathematically. He assumed that the aether particles are moving in every direction, but were thrown back at the outer borders of the vortex and this causes (as in the case of Descartes) a greater concentration of fine matter at the outer borders. So also in his model the fine matter presses the rough matter into the center of the vortex. Huygens also found out that the centrifugal force is equal to the force, which acts in the direction of the center of the vortex (centripetal force).

In mice, it is thought that the lymphatic components form through an angiogenic process. But, there is evidence from bird embryos that gives rise to the idea that lymphatic vessels arise in the embryos through a vasculogenesis-like process from the lymphangioblastic endothelial precursor cells. The development of the lymphatic system has been a highly debated topic in developmental biology for a long time. Previously, it was debated whether the lymph sacs developed from the venous system, or if they came from spaces in the mesenchyme, which come together in a centripetal direction and secondarily opened into the veins.

The engineering challenges of creating a rotating spacecraft are comparatively modest to any other proposed approach. Theoretical spacecraft designs using artificial gravity have a great number of variants with intrinsic problems and advantages. The formula for the centripetal force implies that the radius of rotation grows with the square of the rotating spacecraft period, so a doubling of the period requires a fourfold increase in the radius of rotation. For example, to produce standard gravity, = with a rotating spacecraft period of 15 s, the radius of rotation would have to be , while a period of 30 s would require it to be .

Esperanto has not fragmented into regional dialects through natural language use. This may be because it is the language of daily communication for only a small minority of its speakers. However at least three other factors work against dialects, namely the centripetal force of the Fundamento, the unifying influence of the Plena Vortaro and its successors, which exemplified usage from the works of Zamenhof and leading writers, and the transnational ambitions of the speech community itself. Slang and jargon have developed to some extent, but such features interfere with universal communication – the whole point of Esperanto – and so have generally been avoided.

Ethnic nationalism, based on distinctive religion and language, provided a centripetal force that eventually destroyed the Ottoman Empire.Donald Quataert, Social Disintegration and Popular Resistance in the Ottoman Empire 1881–1908 (1083) In addition, Muslim ethnic groups, which were not part of the millett system, especially the Arabs and the Kurds, were outside the Turkish culture and developed their own separate nationalism. The British sponsored Arab nationalism in the First World War, promising an independent Arab state in return for Arab support. Most Arabs supported the Sultan, but those near Mecca believed in and supported the British promise.

Tesla turbine at Nikola Tesla MuseumThe Tesla turbine is a bladeless centripetal flow turbine patented by Nikola Tesla in 1913.. It is referred to as a bladeless turbine. The Tesla turbine is also known as the boundary-layer turbine, cohesion-type turbine, and Prandtl-layer turbine (after Ludwig Prandtl) because it uses the boundary-layer effect and not a fluid impinging upon the blades as in a conventional turbine. Bioengineering researchers have referred to it as a multiple-disk centrifugal pump. One of Tesla's desires for implementation of this turbine was for geothermal power, which was described in Our Future Motive Power.

When cruising at 10 m/s due East, the total velocity becomes 465 \+ 10 = 475 m/s, which requires a centripetal force of about 0.0354 newtons per kilogram. Cruising at 10 m/s due West the net velocity is 465 − 10 = 455 m/s, requiring about 0.0325 newtons per kilogram. So if the internal weight is neutrally suspended while cruising due East, after reversing course it will not be neutrally suspended any more: the apparent mass of the 10,000-gram internal weight will increase by about 3 grams, and the spring of the gravimeter must extend some more to accommodate this greater weight.

A dice stacker demonstrating stacking five dice. Dice stacking is a performance art, akin to juggling or sleight-of-hand, in which the performer scoops dice off a flat surface with a dice cup and then sets the cup down while moving it in a pattern that stacks the dice into a vertical column via centripetal force and inertia. Various dice arrangements, colors of dice, scooping patterns and props allow for many degrees of complexity and difficulty. Dice stacking is usually performed with canceled casino dice, as their square edges and heavy weight give them an advantage when being stacked.

Instead of a centripetal composition where all the indications point towards a central nucleus, in this painting all the lines of movement shatter the unity of the image into multiple paths towards its margins. The painting can be considered to be an example of the many Romanticist paintings with an organic composition (in this case centrifugal), in relation to the movements and actions of the figures within the painting. This can be contrasted with the mechanical compositions found in Neoclassicism, where angular axises are formed by a painting's contents and imposed by the rational will of the painter.

He utilized leverage and cantilevering, pulleys, cranks, gears, including angle gears and rack and pinion gears; parallel linkage, lubrication systems and bearings. He understood the principles governing momentum, centripetal force, friction and the aerofoil and applied these to his inventions. His scientific studies remained unpublished with, for example, his manuscripts describing the processes governing friction predating the introduction of Amontons' laws of friction by 150 years. It is impossible to say with any certainty how many or even which of his inventions passed into general and practical use, and thereby had impact over the lives of many people.

Wells argues that the speed of land travel stands "in almost fundamental relation to human society." The speeding up of land locomotion will therefore revolutionize human society. Rather than producing even larger cities, a new sort of "human distribution" will be created, with the increase in the distance a worker can travel in an hour acting as a "centrifugal" force leading to a considerable development of "suburbs" while this development is counterbalanced by "centripetal considerations" like a desire for access to shopping districts, good schools, doctors, and "the love of the crowd." The terms "town" and "country" will become obsolete as a new kind of "urban region" develops.

Eden was produced by Centripetal Films and filmed in Washington State in the summer of 2011, with a largely local crew and funding assistance from Washington Filmworks, a government supported non-profit organization that provides financial support for films produced in Washington State. The idea for the film came into being when screenwriter Richard B. Phillips contacted Chong Kim after reading a newspaper article about her account of being sold into and escaping a domestic human trafficking ring. Phillips then proposed the idea of writing a screenplay based on Kim's story. Kim agreed, and the two of them set about writing a story for the film.

A spacecraft enters orbit when its centripetal acceleration due to gravity is less than or equal to the centrifugal acceleration due to the horizontal component of its velocity. For a low Earth orbit, this velocity is about ; by contrast, the fastest piloted airplane speed ever achieved (excluding speeds achieved by deorbiting spacecraft) was in 1967 by the North American X-15. To achieve an orbit, a spacecraft must travel faster than a sub-orbital spaceflight. The energy required to reach Earth orbital velocity at an altitude of is about 36 MJ/kg, which is six times the energy needed merely to climb to the corresponding altitude.

When cultures and individuals accumulate habits and procedures (what Bakhtin calls the "sclerotic deposits" of earlier activity), and adopt forms based in "congealed" events from the past, the centripetal forces of culture will tend to codify them into a fixed set of rules. In the reifying sciences, this codification is mistaken for reality, undermining both creative potential and true insight into past activity. The uniqueness of an event, that which cannot be reduced to a generalization or abstraction, is in fact what makes responsibility, in any meaningful sense, possible: "activity and discourse are always evaluatively charged and context specific."Morson and Emerson (1990). p.

There are only four reasons for low oil pressure: # No oil or low oil in the engine; # Worn or defective oil pump or broken pressure relief valve spring; # Worn main bearings (big ends have nothing to do with oil pressure as most of the pressure to these are supplied by centripetal force); and # Oil gallery fracture or blockage. Low oil pressure can cause engine damage. The first thing to fail will be cam carrier bearings if the vehicle is OHC as this is fed through a restrictor and low pressure will starve the top of the engine of lubrication. If pistons have crown jets (e.g.

If the two agree, one is in a stationary (non-rotating) frame. If the two do not agree, to obtain agreement, one must include a centrifugal force in the tension calculation; for example, if the spheres appear to be stationary, but the tension is non-zero, the entire tension is due to centrifugal force. From the necessary centrifugal force, one can determine one's speed of rotation; for example, if the calculated tension is greater than measured, one is rotating in the sense opposite to the spheres, and the larger the discrepancy the faster this rotation. The tension in the wire is the required centripetal force to sustain the rotation.

On bicycles and motorcycles, camber thrust contributes to the centripetal force necessary to cause the vehicle to deviate from a straight path, along with cornering force due to the slip angle, can be the largest contributor, and in some cases is the sole contributor. Camber thrust contributes to the ability of bikes to negotiate a turn with the same radius as automobiles but with a smaller steering angle. When a bike is steered and leaned in the same direction, the camber angle of the front tire is greater than that of the rear and so can generate more camber thrust, all else being equal.

There is a strong pressure gradient across the isobars toward the center of the cyclone. This pressure gradient provides the centripetal force necessary for the circular motion of each parcel of air. This strong gradient, coupled with the slower speed of the air near the Earth's surface, causes a secondary flow at surface level toward the center of the cyclone, rather than a wholly circular flow. Even though the wind speed near the center of a tropical cyclone is very fast, at any point on the Earth's surface it is not as fast as it is above that point away from the retarding influence of the Earth's surface.

A pressure gradient results from the concave bank toward the other bank. Centripetal forces are necessary for the curved path of each parcel of water, which is provided by the pressure gradient. The primary flow around the bend is vortex flow – fastest speed where the radius of curvature of the stream itself is smallest and slowest speed where the radius is largest.In the absence of secondary flow, bend flow seeks to conserve angular momentum so that it tends to conform to that of a free vortex with high velocity at the smaller radius of the inner bank and lower velocity at the outer bank where radial acceleration is lower.

Street map of Santa Rosa downtown Santa Rosa was founded on the western edge of the Argentine Pampas, in the range of contact of two different natural environments: the end of the plain and the beginning of the land of the Pampas broken valley. The town occupies part of a centripetal basin having their base in Don Tomás Lagoon, where to drain rainwater from the surrounding area. The floor area lies west of it, in hilly terrain where the highest elevations are in the east, with two small plateaus located 200 meters. This high turnover is also observed north, with heights up to 195 meters.

Examples of circular motion include: an artificial satellite orbiting the Earth at a constant height, a ceiling fan's blades rotating around a hub, a stone which is tied to a rope and is being swung in circles, a car turning through a curve in a race track, an electron moving perpendicular to a uniform magnetic field, and a gear turning inside a mechanism. Since the object's velocity vector is constantly changing direction, the moving object is undergoing acceleration by a centripetal force in the direction of the center of rotation. Without this acceleration, the object would move in a straight line, according to Newton's laws of motion.

When cornering, the two biggest limiting factors are downforce and body-roll. Body-roll occurs when the centripetal inertia forces experienced in cornering overload the shock dampers on the outside side of the vehicle, causing the body to ‘lean’, or roll to one side. In conventional suspension designs, having the shock dampers extend perpendicularly from the body creates an increased capacity for body- roll, as forces act directly upwards into the coils. In pull-rod suspension designs, however, having the wishbones and dampers mounted transversely and in line with the body instead translates these forces longitudinally, leaving less room for body-roll and greatly improving cornering grip.

The main instruments and their effects that enabled the shōgun to exercise control over the shugo lords, and to broaden the base of the legitimacy of the regime involved: 1) a continuation of close ties between the Muromachi regime and the imperial court; 2) the compulsory residential policy aimed at the shugo lords; 3) further development of the shogunal army (gobanshu); 4) the rise of shogunal hegemony using the coalition of several shugo lords; and 5) the use of commercial and agrarian revenue and taxes by the regime. All of these changes exemplify the continuing trend of centripetal forces that augmented the power of the regime.

Gemini 11 Agena tethered operations Proposed Nautilus-X International space station centrifuge demo concept, 2011. Artificial gravity (sometimes referred to as pseudogravity) is the creation of an inertial force that mimics the effects of a gravitational force, usually by rotation. Artificial gravity, or rotational gravity, is thus the appearance of a centrifugal force in a rotating frame of reference (the transmission of centripetal acceleration via normal force in the non-rotating frame of reference), as opposed to the force experienced in linear acceleration, which by the equivalence principle is indistinguishable from gravity. In a more general sense, "artificial gravity" may also refer to the effect of linear acceleration, e.g.

If a stone is whirled round on a string, in a horizontal plane, the only real force acting on the stone in the horizontal plane is applied by the string (gravity acts vertically). There is a net force on the stone in the horizontal plane which acts toward the center. In an inertial frame of reference, were it not for this net force acting on the stone, the stone would travel in a straight line, according to Newton's first law of motion. In order to keep the stone moving in a circular path, a centripetal force, in this case provided by the string, must be continuously applied to the stone.

A track transition curve, or spiral easement, is a mathematically-calculated curve on a section of highway, or railroad track, in which a straight section changes into a curve. It is designed to prevent sudden changes in lateral (or centripetal) acceleration. In plane (viewed from above), the start of the transition of the horizontal curve is at infinite radius, and at the end of the transition, it has the same radius as the curve itself and so forms a very broad spiral. At the same time, in the vertical plane, the outside of the curve is gradually raised until the correct degree of bank is reached.

Indeed, what is to stop the dominant force from completely overtaking the weaker, causing the body either to crash into whatever it is orbiting or to fly off at ever accelerating speeds into space? Only the inherent unity of the two Qualities, centripetal and centrifugal, arrived at by the ascension of thought to Absolute Indifference, can adequately explain the Notion of the elliptical orbit, says Hegel. C. Transition into Essence Strictly within the realm of Being, the underlying unity behind all its determinations necessarily stands externally, and in contradiction, to those determinations themselves. The transition to Essence occurs when these determinations reabsorb this unity back into themselves, i.e.

Takumi steps out of the car to the bewilderment of the Speedstars, who were expecting Bunta. He easily defeats Keisuke by utilizing a dangerous "Gutter run" (putting both the right/left tires into the gutters to prevent centripetal force pushing the car outward) technique on the mountain road's hairpin corners. The Red Suns' embarrassing defeat sets up the plot for the rest of the series: drivers from neighboring prefectures come to challenge Takumi and the "Legendary Eight-Six of Akina" and thus prove themselves as racers. Eventually, the plot moves away from Mount Akina as Takumi becomes bored with racing solely on that road.

When an aircraft slows to below its stall speed, it is unable to generate enough lift in order to cancel out the forces that act on the aircraft (such as weight and centripetal force). This will cause the aircraft to drop in altitude. The drop in altitude may cause the pilot to increase the angle of attack by pulling up on the stick, because normally increasing the angle of attack puts the aircraft in a climb. However, when the wing exceeds its critical angle of attack, an increase in angle of attack will lead to a loss of lift and a further loss of airspeed – the wing stalls.

It is customary to derive the equations of motion by formal manipulation in what, to the engineer, amounts to a piece of mathematical sleight of hand. The current approach follows the pitch plane analysis in formulating the equations in terms of concepts which are reasonably familiar. Applying an impulse via the rudder pedals should induce Dutch roll, which is the oscillation in roll and yaw, with the roll motion lagging yaw by a quarter cycle, so that the wing tips follow elliptical paths with respect to the aircraft. The yaw plane translational equation, as in the pitch plane, equates the centripetal acceleration to the side force.

At the equator, the velocity of Earth's surface is about . The amount of centripetal force required to cause an object to move along a circular path with a radius of 6378 kilometres (the Earth's equatorial radius), at 465 m/s, is about 0.034 newtons per kilogram of mass. For a 10,000-gram internal weight, that amounts to about 0.34 newtons. The amount of suspension force required is the mass of the internal weight (multiplied by the acceleration of gravity) minus those 0.34 newtons. In other words: any object co-rotating with the Earth at the equator has its measured weight reduced by 0.34 percent, thanks to the Earth's rotation.

At every other latitude the two are not exactly opposite, so there is a resultant force, that acts towards the Earth's axis. At every latitude there is precisely the amount of centripetal force that is necessary to maintain an even thickness of the atmospheric layer. (The solid Earth is ductile. Whenever the shape of the solid Earth is not entirely in equilibrium with its rate of rotation, then the shear stress deforms the solid Earth over a period of millions of years until the shear stress is resolved.) Again the example of an airship is convenient for discussing the forces that are at work.
|
|
For an airship in flight that means a reduction of the weight, compared to the weight when stationary with respect to the Earth. If the airship has a westward velocity then the situation is like that of a racecar on a banked circuit going too slow: on a slippery surface the car will slump down. For an airship that means an increase of the weight. The first term of the Eötvös effect is proportional to the component of the required centripetal force perpendicular to the local Earth surface, and is thus described by a cosine law: the closer to the Equator, the stronger the effect.

Golden Zephyr is an attraction at Paradise Gardens Park in Disney California Adventure Park built by D. H. Morgan Manufacturing. Themed to the Buck Rogers and Flash Gordon style rocket ships, it takes park guests on a relaxing trip. Unlike its cousins Dumbo and the Astro Orbiter next door in Disneyland, the Golden Zephyr rockets are controlled by centripetal motion over Paradise Bay and can not be automatically controlled to go up and down. The Golden Zephyr's design comes from the Harry Traver Circle-Swing rides of the early 20th century, specifically the Aerostat / Strat-O-Stat ride that operated at Riverview Park in Chicago.

René Descartes' first cosmological treatise, written between 1629 and 1633 and titled The World, included a heliocentric model, but Descartes abandoned it in the light of Galileo's treatment.Weintraub, David A. Is Pluto a Planet, p. 66, Princeton University Press, 2007 In his Principles of Philosophy (1644), Descartes introduced a mechanical model in which planets do not move relative to their immediate atmosphere, but are constituted around space-matter vortices in curved space; these rotate due to centrifugal force and the resulting centripetal pressure. The Galileo affair did little overall to slow the spread of heliocentrism across Europe, as Kepler's Epitome of Copernican Astronomy became increasingly influential in the coming decades.

The key concept is that larger cells tend to stay within the flowing buffer solution while smaller cells will be washed away follow the buffer solution (different sedimentation property within the buffer solution), and cells will have different sedimentation properties in different cell cycle stages. The basic principle of separating the cells inside CCE is the balance between centripetal and the counter flow drag force. When the cells enter the elutriation chamber, all the cells will stay at the outer edge of the chamber due to centrifugal force. Then when the flow rate of the buffer solution increases, the solution tends to push the cells towards the middle of the CCE.

Problem 1 then explores the case of a circular orbit, assuming the center of attraction is on the circumference of the circle. A scholium points out that if the orbiting body were to reach such a center, it would then depart along the tangent. (Proposition 7 in the Principia.) Problem 2 explores the case of an ellipse, where the center of attraction is at its center, and finds that the centripetal force to produce motion in that configuration would be directly proportional to the radius vector. (This material becomes Proposition 10, Problem 5 in the Principia.) Problem 3 again explores the ellipse, but now treats the further case where the center of attraction is at one of its foci.

A very first drawing of a strong black arrow pointing downwards postulates man as a tragic figure always brought down by a plummet (a black arrow) of a gravitational force. However, Klee also points that water and atmosphere are transitional regions, where spirit gets lighter and breaks free. This is a spiritual space open to dynamic positions, new symbols and imaginative co-relations of visual elements (mechanical law of nature versus imaginative vision rendering of an object in art). Continuing further into the final part of the manual ‘Kinetic and Chromatic Energy’, Klee gives examples of ‘creative kinetics’ defying gravitational force such as centripetal force in pendulum and spinning top, or a ‘feathered arrow’.

SUVs are built with higher ground clearance for off-road use and thus have a higher center of gravity, therefore increasing the risk of rollover. When an SUV turns, the vehicle's mass resists the turn and carries the weight forward, thus allowing the traction from the tires to create a lateral centripetal force as the vehicle continues through the turn. The conflict between the top weight of the SUV's desire to go straight while the friction of the tires on the road cause the bottom of the vehicle to move away and out from under the vehicle during a turn. SUVs are more likely to be in rollover accidents than passenger cars.

A charged particle moving through a magnetic field experiences a force perpendicular to the direction of travel, resulting in centripetal acceleration, thereby confining it to move in a circle or helix around the lines of magnetic flux. A solid confinement vessel is also needed, both to shield the magnets and other equipment from high temperatures and energetic photons and particles, and to maintain a near-vacuum for the plasma to populate. The containment vessel is subjected to a barrage of very energetic particles, where electrons, ions, photons, alpha particles, and neutrons constantly bombard it and degrade the structure. The material must be designed to endure this environment so that a power station would be economical.

A Van Hool bi- articulated bus in Hamburg, Germany An AutoTram Extra Grand Bi-articulated bus is presented to the public in alt=A biarticulated low-floor bus with text written in Dutch on, along with other articulated buses. A bi-articulated bus is a long vehicle and usually requires a specially trained driver, as maneuvering (particularly reversing) can be difficult. Articulated electric trolleybuses can be difficult to control, with their motors producing momentary peak power in excess of 600 kilowatts (816 PS; 805 hp). The trailer section of a "puller" bus can be subject to unusual centripetal forces, which many people can find uncomfortable, although this is not an issue with "pushers".

In 2008, Thomas's work Assembly was exhibited at Kashi gallery in Kochi. The show worked as an installation with red plastic chairs placed as though for an official function facing a screen on which were projected a series of photographs, each one of a mundane Kerala street scene framed by a temporary arch of the type typically constructed in the state to announce a social, religious, political or commercial function. The transition between the images was done using a common digital transitional device whereby the image collapsed in a centripetal swirl and re-emerged similarly. The twirl becomes a key to the work, directing and intervening on the rhythms of the viewers' gaze.

A ball in circular motion held by a string tied to a fixed post. The figure at right shows a ball in uniform circular motion held to its path by a string tied to an immovable post. In this system a centripetal force upon the ball provided by the string maintains the circular motion, and the reaction to it, which some refer to as the reactive centrifugal force, acts upon the string and the post. Newton's first law requires that any body not moving in a straight line is subject to a force, and the free body diagram shows the force upon the ball (center panel) exerted by the string to maintain the ball in its circular motion.
|
|
Newton's third law of action and reaction states that if the string exerts an inward centripetal force on the ball, the ball will exert an equal but outward reaction upon the string, shown in the free body diagram of the string (lower panel) as the reactive centrifugal force. The string transmits the reactive centrifugal force from the ball to the fixed post, pulling upon the post. Again according to Newton's third law, the post exerts a reaction upon the string, labeled the post reaction, pulling upon the string. The two forces upon the string are equal and opposite, exerting no net force upon the string (assuming that the string is massless), but placing the string under tension.

The concept of the Renshaw cells was postulated by Birdsey Renshaw (1911–1948),Renshaw B. Central effects of centripetal impulses in axons of spinal ventral roots. J Neurophysiol 1946 9:191–204 when it was discovered that with antidromic signals from a motor neuron running collaterally back via the ventral root into the spinal cord, there were interneurons firing with a high frequency, resulting in inhibition. Later work by Eccles et al.,Eccles JC, Fatt P, Koketsu K. Cholinergic and inhibitory synapses in a pathway from motor-axon collaterals to motoneurones. J. Physiol. 1954;126:524–562. provided evidence that these interneurons, which they called “Renshaw Cells,” are stimulated by acetylcholine from motor neurons (nicotinic receptor).

Another common approach is to dislodge the starch grains through sonication, which is a laboratory technique that uses sound waves to "agitate particles" in order to convert an electrical signal into a vibration which in turn breaks down a substance. In terms of starch grain analysis, the starch grains are released by use of an ultrasonic bath and the distilled water containing the sample particles is then centrifuged. This is the process in which the specimens are spun and separated by density as a result of centripetal force, or due to the fictitious centrifugal force that is felt by the specimens due to their reference frame. Utilizing this force allows for the separation of solutions of different densities.

The British colonies further north, which remained loyal to Britain and later confederated to form the original Canada, retained the title of "province" and are still known as such to the present day. To 19th- and 20th-century historians, in Europe, centralized government was a sign of modernity and political maturity. In the late 20th century, as the European Union drew nation-states closer together, centripetal forces seemed simultaneously to move countries toward more flexible systems of more localized, provincial governing entities under the overall European Union umbrella. Spain after Francisco Franco has been a "State of Autonomies", formally unitary but in fact functioning as a federation of Autonomous Communities, each exercising different powers.

A freewheel assembly is also widely used on engine starters as a kind of protective device. Starter motors usually need to spin at 3,000 RPM to get the engine to turn over. When the key is held in the start position for any amount of time after the engine has started, the starter can not spin fast enough to keep up with the flywheel. Because of the extreme gear ratio between starter gear and flywheel (about 15 or 20:1) it would spin the starter armature at dangerously high speeds, causing an explosion when the centripetal force acting on the copper coils wound in the armature can no longer resist the outward force acting on them.

Turbines have historically been more expensive to produce than piston engines, though this is partly because piston engines have been mass-produced in huge quantities for decades, while small gas turbine engines are rarities; however, turbines are mass-produced in the closely related form of the turbocharger. The turbocharger is basically a compact and simple free shaft radial gas turbine which is driven by the piston engine's exhaust gas. The centripetal turbine wheel drives a centrifugal compressor wheel through a common rotating shaft. This wheel supercharges the engine air intake to a degree that can be controlled by means of a wastegate or by dynamically modifying the turbine housing's geometry (as in a variable geometry turbocharger).

Larger objects distort into an ovoid, and are slightly compressed, which is what happens to the Earth's oceans under the action of the Moon. The Earth and Moon rotate about their common center of mass or barycenter, and their gravitational attraction provides the centripetal force necessary to maintain this motion. To an observer on the Earth, very close to this barycenter, the situation is one of the Earth as body 1 acted upon by the gravity of the Moon as body 2. All parts of the Earth are subject to the Moon's gravitational forces, causing the water in the oceans to redistribute, forming bulges on the sides near the Moon and far from the Moon.

In a vehicle dynamics, the roll moment can be calculated as the product of three quantities: #the vehicle's sprung mass, the portion of its mass supported by the suspension, #whatever lateral acceleration that the vehicle is experiencing, usually centripetal acceleration from a turn, and #the vertical distance between the vehicle's roll axis and its center of mass. In two-axle vehicles, such as cars and some trucks, the roll axis may be found by connecting the roll center of each axle by a straight line. In single-track vehicles, such as bicycles and motorcycles, the roll axis may be found by connecting the contact patches of each tire by a straight line.

In 1671, the Royal Society asked for a demonstration of his reflecting telescope. Their interest encouraged him to publish his notes, Of Colours, which he later expanded into the work Opticks. When Robert Hooke criticised some of Newton's ideas, Newton was so offended that he withdrew from public debate. Newton and Hooke had brief exchanges in 1679–80, when Hooke, appointed to manage the Royal Society's correspondence, opened up a correspondence intended to elicit contributions from Newton to Royal Society transactions, which had the effect of stimulating Newton to work out a proof that the elliptical form of planetary orbits would result from a centripetal force inversely proportional to the square of the radius vector.

Unfortunately an Earth-to-orbit rotovator cannot be built from currently available materials since the thickness and tether mass to handle the loads on the rotovator would be uneconomically large. A "watered down" rotovator with two-thirds the rotational speed, however, would halve the centripetal acceleration stresses. Therefore, another trick to achieve lower stresses is that rather than picking up a cargo from the ground at zero velocity, a rotovator could pick up a moving vehicle and sling it into orbit. For example, a rotovator could pick up a Mach 12 aircraft from the upper atmosphere of the Earth and move it into orbit without using rockets, and could likewise catch such a vehicle and lower it into atmospheric flight.

Book 1 contains some proofs with little connection to real-world dynamics. But there are also sections with far-reaching application to the solar system and universe: Propositions 57–69 deal with the "motion of bodies drawn to one another by centripetal forces". This section is of primary interest for its application to the Solar System, and includes Proposition 66 along with its 22 corollaries: here Newton took the first steps in the definition and study of the problem of the movements of three massive bodies subject to their mutually perturbing gravitational attractions, a problem which later gained name and fame (among other reasons, for its great difficulty) as the three-body problem. Propositions 70–84 deal with the attractive forces of spherical bodies.

The demands for labor has from time to time led to population increases that push the limits of the ecological carrying capacity, and should a period of climatic instability ensue, collapsing central government and declining populations can occur. Alternatively, military vulnerability to invasion from marginal hill tribes or nomadic pastoralists has led to periods of trade collapse and neglect of irrigation systems. Equally, centripetal tendencies amongst city states has meant that central authority over the whole region, when imposed, has tended to be ephemeral, and localism has fragmented power into tribal or smaller regional units.Thompson, William R. (2004) "Complexity, Diminishing Marginal Returns, and Serial Mesopotamian Fragmentation" (Vol 3, Journal of World Systems Research) These trends have continued to the present day in Iraq.

However, if the turntable surface has the correct paraboloid (parabolic bowl) shape (see the figure) and rotates at the corresponding rate, the force components shown in the figure make the component of gravity tangential to the bowl surface exactly equal to the centripetal force necessary to keep the object rotating at its velocity and radius of curvature (assuming no friction). (See banked turn.) This carefully contoured surface allows the Coriolis force to be displayed in isolation.When a container of fluid is rotating on a turntable, the surface of the fluid naturally assumes the correct parabolic shape. This fact may be exploited to make a parabolic turntable by using a fluid that sets after several hours, such as a synthetic resin.

In the left panel of the figure, which is the viewpoint of a stationary observer, the gravitational force in the inertial frame pulling the object toward the center (bottom ) of the dish is proportional to the distance of the object from the center. A centripetal force of this form causes the elliptical motion. In the right panel, which shows the viewpoint of the rotating frame, the inward gravitational force in the rotating frame (the same force as in the inertial frame) is balanced by the outward centrifugal force (present only in the rotating frame). With these two forces balanced, in the rotating frame the only unbalanced force is Coriolis (also present only in the rotating frame), and the motion is an inertial circle.

Thus, a person in the light source's frame would describe the apparent tilting of the beam in terms of aberration, while a person in the observer's frame would describe it as a light-time effect. The relationship between these phenomena is only valid if the observer and source's frames are inertial frames. In practice, because the Earth is not an inertial rest frame but experiences centripetal acceleration towards the Sun, many aberrational effects such as annual aberration on Earth cannot be considered light-time corrections. However, if the time between emission and detection of the light is short compared to the orbital period of the Earth, the Earth may be approximated as an inertial frame and aberrational effects are equivalent to light-time corrections.

In his speech he used words such as "cell" and "metabolism" in relation to urban design. The Metabolist movement grew out of discussions with other members of the conference. Amongst them were Kisho Kurokawa, Junzo Sakakura, Alison and Peter Smithson, Louis Kahn, Jean Prouvé, B. V. Doshi and Jacob Bakema. The conference ended with Tange's presentation of the Boston plan and his own scheme, "The Tokyo Plan – 1960".Stewart (1987), pp. 179–81 Tange argued that the normal urban pattern of a radial centripetal transportation system was a relic of the Middle Ages and would not handle the strain placed upon it by the world's mega cities, which he qualified as those with populations greater than 10 million.Kulterman (1970), p.

Upper panel: Ball on a banked circular track moving with constant speed v; Lower panel: Forces on the ball. The resultant or net force on the ball found by vector addition of the normal force exerted by the road and vertical force due to gravity must equal the required force for centripetal acceleration dictated by the need to travel a circular path. As opposed to a vehicle riding along a flat circle, inclined edges add an additional force that keeps the vehicle in its path and prevents a car from being "dragged into" or "pushed out of" the circle (or a railroad wheel from moving sideways so as to nearly rub on the wheel flange). This force is the horizontal component of the vehicle's normal force.

The 675 cc engine uses a three-cylinder layout, which has given many world titles to the Varese company, but has been enriched by modern technology, such as multi-map wire guidance, to optimise engine performance based on needs and rider's preferences and controlled through simple settings. A counter-rotating (reverse) crankshaft is used, which had previously only been used on MotoGP motorcycles, such as the Yamaha YZR-M1, which counteracts the centripetal forces of the wheels allowing the bike to turn faster. The bore and stroke are 79 mm and 45.9 mm, which is an extremely short-stroke. In conjunction with titanium valves, this allows an extremely high speed engine speed. The engine develops 126 bhp at 14,400 rpm.

Essentially isolated in their community and surrounded by more-or-less hostile neighbors, the native community persisted, it would appear, more by the weight of centripetal forces exterior to the community itself, keeping in check the centrifugal pressures within the community for dissolution. In more concrete terms, the economic and political needs of the State maintained the artificial boundaries and structure of an "Indian" community, well past the date when the community, as an ethnically identifiable social entity, would have dissolved through the typical processes of acculturation and assimilation. To this historically particular moment we add the structural contradictions in the political structure of the Spanish colonies. The point of contact between Crown and Indians was the local administrative authority, the Corregidor.

Players can stick to the wall via centripetal force, but only when the room is spinning sufficiently fast. In the game, Raven must go through multiple levels of the circus environment using various fighting moves to destroy enemies. The game has a normal one-player mode, but it also features a cooperative two-player mode, a one-on-one duel mode where a player can fight against a second player or an enemy character, and a mode where one player controls Raven and the second player controls the generation of the enemies in the game. The game has a "Tweak" mode which allows a player to adjust numerous game variables such as the gravity, the speed of objects, and the appearance of enemies.

A cascade of gas centrifuges at a U.S. enrichment plant The gas centrifuge process uses a large number of rotating cylinders in series and parallel formations. Each cylinder's rotation creates a strong centripetal force so that the heavier gas molecules containing 238U move tangentially toward the outside of the cylinder and the lighter gas molecules rich in 235U collect closer to the center. It requires much less energy to achieve the same separation than the older gaseous diffusion process, which it has largely replaced and so is the current method of choice and is termed second generation. It has a separation factor per stage of 1.3 relative to gaseous diffusion of 1.005, which translates to about one-fiftieth of the energy requirements.

There was virtually no middle class in the South to balance the local interests and centripetal power of the entrenched aristocracy, who retained the feudal independence that had been their bargain with the Angevins' Norman predecessors. He was remembered by Petrarch and Boccaccio as a cultured man and a generous patron of the arts, "unique among the kings of our day," Boccaccio claimed after Robert's death, "a friend of knowledge and virtue."Kelly, Samantha, The New Solomon: Robert of Naples (1309-1343) and Fourteenth-Century Kingship, page 2 Google Books Petrarch asked to be examined by Robert before being crowned as poet in the Campidoglio in Rome (1341); his Latin epic Africa is dedicated to Robert, though it was not made available to readers until 1397, long after both Petrarch and Robert were dead.

Accordingly, we shall recognise the same forms under other names; but at each return more specific and intense; and the whole process repeated with ascending gradations of reality, exempli gratiâ: Time + space = motion; Tm + space = line + breadth = depth; depth + motion = force; Lf + Bf = Df; LDf + BDf = attraction + repulsion = gravitation; and so on, even till they pass into outward phenomena, and form the intermediate link between productive powers and fixed products in light, heat, and electricity. Matter, then, is the product of the dynamic forces - repulsion (centrifugal), and attraction (centripetal); it is not itself a productive power. It is also the mass of a given body. :If we pass to the construction of matter, we find it as the product, or tertium aliquid, of antagonist powers of repulsion and attraction.

There are three primary ways for an aircraft to change its orientation relative to the passing air. Pitch (movement of the nose up or down, rotation around the transversal axis), roll (rotation around the longitudinal axis, that is, the axis which runs along the length of the aircraft) and yaw (movement of the nose to left or right, rotation about the vertical axis). Turning the aircraft (change of heading) requires the aircraft firstly to roll to achieve an angle of bank (in order to produce a centripetal force); when the desired change of heading has been accomplished the aircraft must again be rolled in the opposite direction to reduce the angle of bank to zero. Lift acts vertically up through centre of pressure which depends on the position of wings.

In the first case a mathematical formulation mirrors centrifugal force; in the second it creates it. Christiaan Huygens coined the term "centrifugal force" in his 1659 De Vi Centrifuga and wrote of it in his 1673 Horologium Oscillatorium on pendulums. In 1676–77, Isaac Newton combined Kepler's laws of planetary motion with Huygens' ideas and found > the proposition that by a centrifugal force reciprocally as the square of > the distance a planet must revolve in an ellipsis about the center of the > force placed in the lower umbilicus of the ellipsis, and with a radius drawn > to that center, describe areas proportional to the times. Newton coined the term "centripetal force" (vis centripeta) in his discussions of gravity in his De motu corporum in gyrum, a 1684 manuscript which he sent to Edmond Halley.

When understeering, the steering angle must be greater, and when oversteering, the steering angle must be less than it would be if the slip angles were equal to maintain a given turn radius. Some authors even use the term counter-steering to refer to the need on some bikes under some conditions to steer in the opposite direction of the turn (negative steering angle) to maintain control in response to significant rear wheel slippage. Fourth, camber thrust contributes to the centripetal force necessary to cause the bike to deviate from a straight path, along with cornering force due to the slip angle, and can be the largest contributor. Camber thrust contributes to the ability of bikes to negotiate a turn with the same radius as automobiles but with a smaller steering angle.

Most Oxfords in the UK were equipped with a knotted rope from the pilot's seat to the rear door to assist evacuation should the plane inadvertently be put into a spin, which it was almost impossible to recover from. When the pilot(s) released their seat belts centripetal force would hurl them to the rear of the plane, beyond the exit door, from which it was impossible to crawl forward to the door. The rope was installed as a response to a test by four "boffins" who tried to recover from a spin from 18,000 ft. When no recovery happened no matter what was tried the four released their harness and were hurled to the rear of their plane and there remained helpless as the spiral descent continued.

This emerging missional renewal movement has been inspired by the old orders. They exist on the outer edge of the mainstream church like the old orders, and they enjoy many of the disciplines and liturgies developed within the old orders. What's more, they have benefited from some of the organizational, entrepreneurial, and strategic thinking of modern, evangelical missions agencies. While these groups often parallel western communities who identify with the New Monasticism, the new monastic communities may be characterized by a centripetal force, renewing the church and the neighborhoods in which they exist by drawing people in, while the new friars by a centrifugal one, whose energy moves outward to the global margins, seeking to raise up and mobilize members to move into the cities of the majority world.

Motoki and Shizuki collaborated on translations of Dutch scientific treatises, and helped introduce and popularize Newtonian mechanics to Japanese scholars, as well as ideas about planetary motion and calendrics ultimately derived from Copernicus and Johannes Kepler. Shizuki's commentaries draw heavily from John Keill's, though Shizuki also generated his own ideas in his commentaries, and sought to reconcile Western philosophies of science with traditional Confucian metaphysical ideas. His best-known work was Rekisho Shinsho, or New Treatise on Calendrical Phenomena, which he completed in 1802 and which was heavily indebted to Keill's works, several of which Shizuki had already translated by that time. Several of the Japanese terms that Shizuki used in translating Newtonian mechanical ideas, including those for gravity and centripetal force, were adopted into the Japanese scientific lexicon and remain in common use.

Vandenbrink Carver (1F1T) Tripendo recumbent tricycle, a tilting three-wheeler (2F3T) Yamaha Niken from 2018 UWM PantherTrike, a narrow-track, tilting, recumbent, human-powered trike (1F3T) A tilting three-wheeler, tilting trike, leaning trike, or even just tilter, is a three-wheeled vehicle and usually a narrow-track vehicle whose body and or wheels tilt in the direction of a turn. Such vehicles can corner without rolling over despite having a narrow axle track because they can balance some or all of the roll moment caused by centripetal acceleration with an opposite roll moment caused by gravity, as bicycles and motorcycles do. This also reduces the lateral acceleration experienced by the rider, which some find more comfortable than the alternative. The narrow profile can result in reduced aerodynamic drag and increased fuel efficiency.

Schematic of a pair of Dean vortices that form in curved pipes. If a fluid is moving along a straight pipe that after some point becomes curved, the centripetal forces at the bend will cause the fluid particles to change their main direction of motion. There will be an adverse pressure gradient generated from the curvature with an increase in pressure, therefore a decrease in velocity close to the convex wall, and the contrary will occur towards the outer side of the pipe. This gives rise to a secondary motion superposed on the primary flow, with the fluid in the centre of the pipe being swept towards the outer side of the bend and the fluid near the pipe wall will return towards the inside of the bend.

Cut through a 2-1 junction in an exhaust manifold showing pressure, which is nonhomogeneous due to centripetal forces, and flow. When an engine starts its exhaust stroke, the piston moves up the cylinder bore, decreasing the total chamber volume. When the exhaust valve opens, the high pressure exhaust gas escapes into the exhaust manifold or header, creating an "exhaust pulse" comprising three main parts: # The high-pressure head is created by the large pressure difference between the exhaust in the combustion chamber and the atmospheric pressure outside of the exhaust system # As the exhaust gases equalize between the combustion chamber and the atmosphere, the difference in pressure decreases and the exhaust velocity decreases. This forms the medium-pressure body component of the exhaust pulse # The remaining exhaust gas forms the low-pressure tail component.

Forces occurring between the motorcycle and the road (such as those that result in accelerating, decelerating and turning) occur at the contact patch through friction and normal forces. There is a limited amount of force tangential to the road that the contact patch can transmit before the tire begins to lose traction, and therefore slide or skid. When going through a curve on a motorcycle, centripetal force (added to the other lateral forces such as acceleration or deceleration) is transferred from the road to the motorcycle through the contact patch, and is directed at a right angle to the path of travel. If the net force is greater than the static friction coefficient of the tire multiplied by the normal force of the motorcycle through the tire, the tire will skid outwards from the direction of the curve.

The retinal nerve fiber layer (RNFL) or nerve fiber layer, stratum opticum, is formed by the expansion of the fibers of the optic nerve; it is thickest near the optic disc, gradually diminishing toward the ora serrata. As the nerve fibers pass through the lamina cribrosa sclerae they lose their medullary sheaths and are continued onward through the choroid and retina as simple axis-cylinders. When they reach the internal surface of the retina they radiate from their point of entrance over this surface grouped in bundles, and in many places arranged in plexuses. Most of the fibers are centripetal, and are the direct continuations of the axis-cylinder processes of the cells of the ganglionic layer, but a few of them are centrifugal and ramify in the inner plexiform and inner nuclear layers, where they end in enlarged extremities.

The force of gravity (red), the buoyancy force (green), and the resultant centripetal force (blue) In the following discussion, g represents the acceleration due to gravity, \omega represents the angular speed of the liquid's rotation, in radians per second, m is the mass of an infinitesimal parcel of liquid material on the surface of the liquid, r is the distance of the parcel from the axis of rotation, and h is the height of the parcel above a zero to be defined in the calculation. The force diagram (shown) represents a snapshot of the forces acting on the parcel, in a non-rotating frame of reference. The direction of each arrow shows the direction of a force, and the length of the arrow shows the force's strength. The red arrow represents the weight of the parcel, caused by gravity and directed vertically downward.

Instead of a Kuznets curve, he breaks the population into deciles and examines the relationship between their respective incomes and income inequality. Palma then shows that there are two distributional trends taking place in inequality within a country: > "One is 'centrifugal', and takes place at the two tails of the > distribution—leading to an increased diversity across countries in the > shares appropriated by the top 10 percent and bottom forty percent. The > other is 'centripetal', and takes place in the middle—leading to a > remarkable uniformity across countries in the share of income going to the > half of the population located between deciles 5 to 9." Therefore, it is the share of the richest 10% of the population that affects the share of the poorest 40% of the population with the middle to upper-middle staying the same across all countries.

It was shown by Herglotz (1911),Herglotz (1911) that a relativistic theory of elasticity can be based on the assumption, that stresses arise when the condition of Born rigidity is broken.Pauli (1921) An example of breaking Born rigidity is the Ehrenfest paradox: Even though the state of uniform circular motion of a body is among the allowed Born rigid motions of class B, a body cannot be brought from any other state of motion into uniform circular motion without breaking the condition of Born rigidity during the phase in which the body undergoes various accelerations. But if this phase is over and the centripetal acceleration becomes constant, the body can be uniformly rotating in agreement with Born rigidity. Likewise, if it is now in uniform circular motion, this state cannot be changed without again breaking the Born rigidity of the body.

Diabaté’s biographer, Cheick M. Chérif Keïta, views Diabaté’s life, and many of his works, as the result of a dialectic between two opposing forces, Fasiya and Fadenya: > Fasiya represents the artist's attachment to the forms and practices that > existed in society before his birth… Fasiya is a centripetal force in that > it drives the artist to create within a tradition in accordance with the > canons embodied by his father and paternal lineage. The second force is > Fadenya, the instinct to compete with and rebel against those models of past > times, embodied by the father and paternal lineage… it is this desire to > distinguish oneself from one's ancestors that promotes the creation of new > forms of expression and the individual discovery of new aesthetics.Keïta > 1995, p.9-10 Diabaté took on the role of griot as this was assigned to him by his lineage.

At the end of the boil, solid particles in the hopped wort are separated out, usually in a vessel called a "whirlpool" or "settling tank". The whirlpool was devised by Henry Ranulph Hudston while working for the Molson Brewery in 1960 to utilise the so-called tea leaf paradox to force the denser solids known as "trub" (coagulated proteins, vegetable matter from hops) into a cone in the centre of the whirlpool tank. Whirlpool systems vary: smaller breweries tend to use the brew kettle, larger breweries use a separate tank, and design will differ, with tank floors either flat, sloped, conical or with a cup in the centre. The principle in all is that by swirling the wort the centripetal force will push the trub into a cone at the centre of the bottom of the tank, where it can be easily removed.

The novel also requires constant physical manipulation to read, whereas only certain sections of House of Leaves require readers to flip the book around. The book's content, of course, is purely of Danielewski's own invention, although he allegedly had a chance meeting with a couple of young lovers while on tour for House of Leaves who served as inspirations for his lead characters in Only Revolutions, Sam and Hailey and Hailey and Sam. As the work progressed it became obvious to Mark that the novel was something of a counterpoint to House of Leaves; in fact, he has said in interviews that Only Revolutions is centrifugal while House of Leaves is centripetal. This aspect of the novel was brought to the forefront in the endpapers in the hardback versions of Only Revolutions, released September 12, 2006, as well as the "A Spoiler" published by the French literary magazine Inculte in 2007.

The SOHO spacecraft is in a halo orbit around the Sun–Earth L1 point, the point between the Earth and the Sun where the balance of the (larger) Sun's gravity and the (smaller) Earth's gravity is equal to the centripetal force needed for an object to have the same orbital period in its orbit around the Sun as the Earth, with the result that the object will stay in that relative position. Although sometimes described as being at L1, the SOHO spacecraft is not exactly at L1 as this would make communication difficult due to radio interference generated by the Sun, and because this would not be a stable orbit. Rather it lies in the (constantly moving) plane, which passes through L1 and is perpendicular to the line connecting the Sun and the Earth. It stays in this plane, tracing out an elliptical halo orbit centered about L1.

The Eötvös effect for an object moving eastward along 60 degrees latitude. The object tends to move away from the Earth's axis. The Eötvös effect for an object moving westward along 60 degrees latitude. The object tends to be pulled towards the Earth's axis. The same gravimeter is used again, its internal weight has a mass of 10,000 grams. Calculating the weight reduction when stationary with respect to the Earth: An object located at 60 degrees latitude, co-moving with the Earth, is following a circular trajectory, with a radius of about 3190 kilometer, and a velocity of about 233 m/s. That circular trajectory requires a centripetal force of about 0.017 newton for every kilogram of mass; 0.17 newton for the 10,000 gram internal weight. At 60 degrees latitude, the component that is perpendicular to the local surface (the local vertical) is half the total force.

The policy, which was never discussed in Chinese public statements, is officially dormant now and the Chinese claims remain only on the Indian state of Arunachal Pradesh and the Aksai Chin region India claims as part of Ladakh which is administered by China mostly as part of Hotan Prefecture, Xinjiang with a small portion administered as part of Ngari Prefecture, Tibet. However, fears have been expressed regarding its revival. After the 2017 China–India border standoff at Doklam, an article in Qunzhong (mouthpiece magazine of CCP's Jiangsu provincial party standing committee) invoked the "five fingers" construct. The article, which was written by Nanjing University researcher Liu Litao, alleged that India's covert support to the Tibetan independence movement stems from Tibet's cultural and economic importance in the region and that despite the fact that India has "taken away the five fingers", it is impossible to fully control the region without the "palm" because of Tibetan culture's "centripetal force" on the "five fingers".

The empowerment of the szlachta and the incremental limitation of monarchic power in Poland can be seen as parallel to the guarantees made to the barons in Magna Carta, the precursor to the parliamentary ideals of Great Britain and, to a lesser extent, the United States, within which genuine democracy has evolved. In contrast with the centralizing of power during the 15th century by the so-called "New Monarchs" of Western Europe, the empowerment of the szlachta can be interpreted as a centripetal movement, to localized aristocratic power and a weak central state, which "had become merely an institution stripped of all substance", as Fernand Braudel remarked. The dominance of the szlachta over other classes and the monarch was unprecedented in the contemporary Europe. At the same time it was paid for by the weakening of the other classes (peasantry and townsfolk), and the central (royal) power, which led to the weakening of the Polish state.

There was also an optimistic aspect to Puritan millennianism; Puritans anticipated a future worldwide religious revival before the Second Coming of Christ. Another departure from other Protestants was the widespread belief among Puritans that the conversion of the Jews to Christianity was an important sign of the apocalypse. David Brady describes a "lull before the storm" in the early 17th century, in which "reasonably restrained and systematic" Protestant exegesis of the Book of Revelation was seen with Brightman, Mede, and Hugh Broughton, after which "apocalyptic literature became too easily debased" as it became more populist and less scholarly. William Lamont argues that, within the church, the Elizabethan millennial beliefs of John Foxe became sidelined, with Puritans adopting instead the "centrifugal" doctrines of Thomas Brightman, while the Laudians replaced the "centripetal" attitude of Foxe to the "Christian Emperor" by the national and episcopal Church closer to home, with its royal head, as leading the Protestant world iure divino (by divine right).

The weighing scale measures normal force (which varies as the elevator cab accelerates), not gravitational force (which does not vary as the cab accelerates). When we define upward to be the positive direction, constructing Newton's second law and solving for the normal force on a passenger yields the following equation: :N = m(g + a) In a gravitron ride, the static friction caused by and perpendicular to the normal force acting on the passengers against the walls results in suspension of the passengers above the floor as the ride rotates. In such a scenario, the walls of the ride apply normal force to the passengers in the direction of the center, which is a result of the centripetal force applied to the passengers as the ride rotates. As a result of the normal force experienced by the passengers, the static friction between the passengers and the walls of the ride counteracts the pull of gravity on the passengers, resulting in suspension above ground of the passengers throughout the duration of the ride.

Earth Alliance space stations such as the Babylon series (hence the name of the series), transfer stations such as the one at Io near the main Sol system jump gate, and EarthForce Omega-Class Destroyers made extensive use of rotating sections to lengthen deployment times and increase mission flexibility as the effects of zero gravity are no longer a concern. 1999: The Japanese manga and anime Planetes has its main story set in "The Seven," the 7th wheel orbital station, and a 9th is under construction by 2075. In the Zenon trilogy (Zenon: Girl of the 21st Century, Zenon: The Zequel and Zenon: Z3), 13-year-old Zenon lives on a rotating space station owned by the fictional WyndComm from 2049 though 2054, but it is not designed in a way that would allow for artificial gravity through centripetal force. 2000: In the film Mission to Mars, Mars II, a NASA spacecraft hastily repurposed for a recovery mission of humanity's first mission to Mars in 2020, features a rotating crew habitat whose artificial gravitational rotation was shut down using the ship's attitude control thrusters to allow emergency repairs to the hull following a micrometeoroid shower.
