The machines and drives in the turbine house date back to 1920, when the looms were converted to electric operation. In the basement there is the turbine, guide vanes and water chamber. In the engine room, the large bevel gear wheel, which sits on the turbine axis and is equipped with original wooden teeth from 1920, is set in motion by the rotational force of the turbine. With the small bevel gear wheel and the transmissions, the rotational force is transmitted to the bevel shaft, which drives the generator at 1000 revolutions per minute.

So although the wheels can rotate at different speeds, they apply the same rotational force, even if one is entirely stationary, and the other spinning. (Equal torque, unequal rotational speed). By contrast, a locked differential forces both left and right wheels on the same axle to rotate at the same speed under nearly all circumstances, without regard to tractional differences seen at either wheel. Therefore, each wheel can apply as much rotational force as the traction under it will allow, and the torques on each side-shaft will be unequal.

The BLT was deployed for a length of 10 months and conducted numerous bi-lateral training exercises with foreign nations. In April 2013, the majority of the battalion deployed in support of the Black Sea Rotational Force, while Fox Company conducted combat operations around Nad Ali and surrounding areas in Helmand Province in support of Operation Enduring Freedom returning later that year. In August 2014, the unit deployed in support of the SPMAGTF-CR Africa and the Black Sea Rotational Force. Conducting training with the Spanish, Italian, French, and other NATO members, the unit returned home in January 2015. In February 2016, 2/2 deployed as part of the UDP based out of Okinawa, Japan.

When the crank on the right is turned, the shaft moves horizontally through the hole. A screw is a mechanism that converts rotational motion to linear motion, and a torque (rotational force) to a linear force. It is one of the six classical simple machines. The most common form consists of a cylindrical shaft with helical grooves or ridges called threads around the outside.

Dynamics, Theory and Applications pp. 90–99: Free download. For example, a rotational force applied to a shaft causing acceleration, such as a drill bit accelerating from rest, results in a moment called a torque. By contrast, a lateral force on a beam produces a moment (called a bending moment), but since the angular momentum of the beam is not changing, this bending moment is not called a torque.

Leg dominance describes the observation that women tend to place more weight on one leg than another. Finally, trunk dominance suggests that males typically exhibit greater control of the trunk in performance situations as evidenced by greater activation of the internal oblique muscle. Female athletes are more likely land with their upper body tilted to one side and more weight on one leg than the other, therefore placing greater rotational force on their knees.

236x236px An electric motor converts electrical energy into mechanical energy. The reverse process of electrical generators, most electric motors operate through interacting magnetic fields and current-carrying conductors to generate rotational force. Motors and generators have many similarities and many types of electric motors can be run as generators, and vice versa. Electric motors are found in applications as diverse as industrial fans, blowers and pumps, machine tools, household appliances, power tools, and disk drives.

An advantage of jackscrews over some other types of jack is that they are self-locking, which means when the rotational force on the screw is removed, it will remain motionless where it was left and will not rotate backwards, regardless of how much load it is supporting. This makes them inherently safer than hydraulic jacks, for example, which will move backwards under load if the force on the hydraulic actuator is accidentally released.

Fox Company returned again from Afghanistan October 2013, while the rest of the battalion returned home August 2013 from the Black Sea Rotational Force. Then again in August 2014, the battalion deployed in support of the SPMAGTF-CR Africa. Returning in January 2015, the unit next deployed to the Pacific region on a UDP, going to Okinawa, Japan; the Philippines; Korea; Thailand; and Singapore. The unit is now slated to deploy again in the near future.

A two-pulley jackshaft redirecting belt power from horizontal to vertical. A jackshaft, also called a countershaft, is a common mechanical design component used to transfer or synchronize rotational force in a machine. A jackshaft is often just a short stub with supporting bearings on the ends and two pulleys, gears, or cranks attached to it. In general, a jackshaft is any shaft that is used as an intermediary transmitting power from a driving shaft to a driven shaft.

Depending on the design of the machine, the upper tooling may hold a part to be joined or simply apply the necessary pressure and impart rotation to one of the parts being joined. For parts that held in place by the upper tooling prior to the start of welding, press fitting the part will prevent dropping prior to welding. Drive pins, serrations, or a grit blasted finish may be used to help the upper tooling impart rotational force on the part.

One of the problems with any single set of rotor blades is the torque (rotational force) exerted on the helicopter fuselage in the direction opposite to the rotor blades. This torque causes the fuselage to rotate in the direction opposite to the rotor blades. In single rotor helicopters, the antitorque rotor or tail rotor counteracts the main rotor torque and controls the fuselage rotation. Coaxial rotors solve the problem of main rotor torque by turning each set of rotors in opposite directions.

The reactive forces from the fired bullet and propellant gases exiting the muzzle act directly down the centerline of the barrel. If that line of force is above the center of the contact points, this creates a moment or torque (rotational force) that causes the firearm to rotate and the muzzle to rise. The M1946 Sieg automatic rifle had an unusual muzzle brake that made the rifle climb downward, but enabled the user to fire it with one hand in full automatic.

Two bases at Constanţa, Romania was developed, apparently with the main facility at Mihail Kogălniceanu Airfield. Initially, however, Joint Task Force East was to have been provided by a rotational 2nd Cavalry Regiment Stryker squadron. The Task Force was originally planned to be called the Eastern Europe Task Force. However, since the stresses of the Iraq and Afghan deployments, the army provision of the Joint Task Force East has been replaced by a Marine force known as the Black Sea Rotational Force.

A high-speed dental handpiece. Head of the dental drill A dental drill or handpiece is a hand-held, mechanical instrument used to perform a variety of common dental procedures, including removing decay, polishing fillings, performing cosmetic dentistry, and altering prostheses. The handpiece itself consists of internal mechanical components which initiate a rotational force and provide power to the cutting instrument, usually a dental burr. The type of apparatus used clinically will vary depending on the required function dictated by the dental procedure.

High-G training is done by aviators and astronauts who are subject to high levels of acceleration ('G') in large-radius centrifuges. It is designed to prevent a g-induced loss Of consciousness (abbreviated G-LOC), a situation when g-forces move the blood away from the brain to the extent that consciousness is lost. Incidents of acceleration-induced loss of consciousness have caused fatal accidents in aircraft capable of sustaining high-g for considerable periods. In amusement parks, pendulum rides and centrifuges provide rotational force.

The battalion deployed in 2017 from April to October to Darwin Australia under the Marine Corp's Unit Deployment Program as Marine Rotational Force - Darwin (MRF-D). Multinational training programs were executed with participants from Australia, Japan, France and elements from the United States Army and the United States Special Operations Command. During the deployment 3rd Battalion 4th Marines established itself as a Marine Air Ground Task Force (MAGTF). Supporting elements came from tilt wing and rotary wing helicopter squadrons, logistics units, and engineering elements.

When one engine fails, a yawing moment develops, which applies a rotational force to the aircraft that tends to turn it toward the wing that carries the engine that failed. A rolling moment might develop, due to the asymmetry of the lift in each wing, with a greater lift generated by the wing with the operating engine. The yawing and rolling moments apply rotational forces that tend to yaw and roll the aircraft towards the failed engine. This tendency is counteracted by the pilot's use of the flight controls, which include the rudder and ailerons.

When the rotor is stationary, no net rotational force arises, even if the wind speed rises quite high—the rotor must already be spinning to generate torque. Thus the design is not normally self-starting. Under rare conditions, Darrieus rotors can self-start, so some form of brake is required to hold it when stopped. One problem with the design is that the angle of attack changes as the turbine spins, so each blade generates its maximum torque at two points on its cycle (front and back of the turbine).

The Army component of EETAF would be a Brigade Combat Team (BCT) rotating on a four to six-month basis from the continental U.S. or Europe. The March 2006 Strategic Planning Guidance modified the presence requirement from a full-time BCT to a “periodic rotational force.” U.S. Secretary of State Condoleezza Rice signed the Defense Cooperation Agreement with Romania in 2005 and Bulgaria in 2006 dictating the stipulations of the two bi-lateral agreements. The EETAF concept described a two-phased process to “start small and grow” the objective capability.

Like the other simple machines a screw can amplify force; a small rotational force (torque) on the shaft can exert a large axial force on a load. The smaller the pitch (the distance between the screw's threads), the greater the mechanical advantage (the ratio of output to input force). Screws are widely used in threaded fasteners to hold objects together, and in devices such as screw tops for containers, vises, screw jacks and screw presses. Other mechanisms that use the same principle, also called screws, don't necessarily have a shaft or threads.

A bouncing ball tribometer consists of a ball which is impacted at an angle against a surface. During a typical test, a ball is slid on an angle along a track until it impacts a surface and then bounces off of the surface. The friction produced in the contact between the ball and the surface results in a horizontal force on the surface and a rotational force on the ball. Frictional force is determined by finding the rotational speed of the ball using high speed photography or by measuring the force on the horizontal surface.

Importantly, \omega is the same frequency, and the two driving forces are said to be phase locked. The confluence of two phase matched driving forces in orthogonal directions gives rise to a rotational force on the centre of mass at the propeller end, and thus, rotation. When the operator of the whammy-diddle surreptitiously changes the side at which their finger contacts the stick (e.g. by contacting with the thumb instead of the fore-finger, or by changing the side at which a finger contacts the grooves of the base) they change the sign of the phase \phi, and thus reverses the rotation.

A screw thread is the essential feature of the screw as a simple machine and also as a threaded fastener. The mechanical advantage of a screw thread depends on its lead, which is the linear distance the screw travels in one revolution. In most applications, the lead of a screw thread is chosen so that friction is sufficient to prevent linear motion being converted to rotary, that is so the screw does not slip even when linear force is applied, as long as no external rotational force is present. This characteristic is essential to the vast majority of its uses.

If it has sufficient strength to overcome any resistance it will cause the object to move ("translate"). A pair of forces, acting on the same "line of action" but in opposite directions, will cancel; if they cancel (balance) exactly there will be no net translation, though the object will experience stress, either tension or compression. If the pair of forces are offset, acting along parallel but separate lines of action, the object experiences a rotational force, or torque. In mechanics (the branch of physics concerned with the interactions of forces) this model is called a couple, also simple couple or single couple.

A manual impact driver with screwdriver bits and adapters Impact driver guide set with bits A manual impact driver is a tool that delivers a strong, sudden rotational force and forward thrust when struck on the back with a hammer. It is often used by mechanics to loosen larger screws (bolts) and nuts that are corrosively "frozen" or over-torqued. The direction can also be reversed for situations where screws have to be tightened with torque greater than a screwdriver can reasonably provide. Manual impact drivers consist of a heavy outer sleeve that surrounds an inner core that is splined to it.

400px A commutator consists of a set of contact bars fixed to the rotating shaft of a machine, and connected to the armature windings. As the shaft rotates, the commutator reverses the flow of current in a winding. For a single armature winding, when the shaft has made one-half complete turn, the winding is now connected so that current flows through it in the opposite of the initial direction. In a motor, the armature current causes the fixed magnetic field to exert a rotational force, or a torque, on the winding to make it turn.

In November 2012, 1/5 deployed as a Battalion Landing Team (BLT) as part of the 31st Marine Expeditionary Unit. 1/5 completed a six-month rotation including a deployment to Thailand in support of exercise Cobra Gold 2013. The Battalion was relieved by fellow 5th Marines Battalion 2/4 and returned to Camp Pendleton in late May 2013, completing a six-month rotation including a deployment to the Kingdom of Thailand in support of exercise Cobra Gold 2013. From March 2014 to October 2014, 1/5 deployed to Darwin, Australia as the ground combat element of Marine Rotational Force-Darwin.

In a correctly constructed pool, rotation of the water caused by the manner it is returned from the consecutive dilution system will reduce or even waive the need to vacuum the bottom. To gain the maximum rotation force on the main body of water, the consecutive dilution system needs to be as clean and unblocked as possible to allow maximum flow pressure from the pump. As the water rotates, it also disturbs organic waste at lower water layers, forcing it to the top. Rotational force the pool return jets create is the most important part of cleaning the pool water and pushing organic waste across the mouth of the skimmer.

As well as these facilities, between 200 and 300 US Military personnel are posted to Australia to liaise with the ADF. In November 2011, the Australian and American Governments announced plans to base on rotational basis a United States Marine Corps Marine Air-Ground Task Force in the Northern Territory for training and exercise purposes and also plans to increase rotations of United States Air Force (USAF) aircraft through northern Australia. As part of this agreement, the Marine Rotational Force – Darwin has been deployed to Australia for six months each year since 2012. It is planned for this force to eventually comprise around 2,500 personnel with supporting aircraft and equipment.

It may also occur in football, for example, when a player is on the ground with their leg behind them, the foot at right angles, and a rotational force is suddenly applied to the heel, as when someone falls on their foot. Overall, the most common mechanism is external rotation and may occur with sufficient rapidity that the actual mechanism is unrecognized. In this sequence of events, the most vulnerable structure is the anterior inferior tibio-fibular ligament, uniting the lower end of the tibia and fibula and playing an important role in the maintenance of the mortise. The injury to this ligament may vary from simple stretch to complete rupture.

ARB air-locking differential fitted to a Mitsubishi Delica L400 LWB Diff A locking differential is designed to overcome the chief limitation of a standard open differential by essentially "locking" both wheels on an axle together as if on a common shaft. This forces both wheels to turn in unison, regardless of the traction (or lack thereof) available to either wheel individually. When the differential is unlocked (open differential), it allows each wheel to rotate at different speeds (such as when negotiating a turn), thus avoiding tire scuffing. An open (or unlocked) differential always provides the same torque (rotational force) to each of the two wheels, on that axle.

Using a logarithmic spiral shape resulted in a uniform angle between the rock and each lobe of the cam; this constant angle is designed to always provide the necessary friction to hold a cam in equilibrium.Duke SLCD research retrieved (2009-08-05) Designed so that a load produces a rotational force, the logarithmic cam shape allowed for a single device to fit securely in a range of crack sizes. Modern SLCDs were invented by Ray Jardine in 1978 (US patent 4,184,657) and sold under the brand name of "Friends". Ray designed a spring-loaded opposing multiple cam unit with a more stable 13.75 degree camming angle and an innovative triggering mechanism.

The host unit at RAF Mildenhall is the 100th Air Refueling Wing (100 ARW), which deploys aircraft for and manages the European Tanker Task Force, a rotational force which provides air refuelling to US and NATO aircraft in the European Theatre. It is the only permanent USAF air refuelling wing in the European theatre, activated at RAF Mildenhall on 1 February 1992. The wing provides the critical air refuelling 'bridge' that allows the Expeditionary Air Force to deploy around the globe with the appropriate urgency. The tactical component of the 100 ARW is the 351st Air Refueling Squadron (351 ARS), flying the Boeing KC-135R Stratotanker.

In rotational movement, the head turns around its center of gravity and in angular movement, it turns on an axis, not through its center of gravity. The amount of rotational force is thought to be the major component in concussion and its severity. Studies with athletes have shown that the amount of force and the location of the impact are not necessarily correlated with the severity of the concussion or its symptoms, and have called into question the threshold for concussion previously thought to exist at around 70–75 g. The parts of the brain most affected by rotational forces are the midbrain and diencephalon.

Current usage favors mounted guns, either vehicular or emplaced, where the fire rate necessitates multiple barrels to space out the use of each to avoid melting a single barrel at full auto fire. These guns are not able to be fired by humans, and attempting to do so can be fatal as the rotational force from the extreme rapid rotation of modern miniguns throws the gun at the user if it is not secured. The Fairchild Republic A-10 Thunderbolt II, also known as a "Warthog" or a "Hog" (entering service around 1976), is a USA ground-attack plane built around a 30 mm GAU-8 Avenger rotary cannon, a powerful modern version of the Gatling gun.

The green circle, passing through the six points of contact between the two components, represents the direction of the rotational force being exerted at each of those points. Because the plane of contact is not perpendicular to this circle, a radial force is also generated which tends to "burst" the female component and "crush" the male one. If this radial force component is too great for the material to withstand, it will cause the corners to be rounded off one or both components or will split the sides of the female part. The magnitude of this force is proportional to the cotangent of the angle (depicted in orange) between the green circle and the contact plane.

In effect these spaces serving the same purpose as the cylinders of an axial engine, and the sinuous cam surface acts as the face of the pistons. In other respect this form follows the normal cycles of internal combustion but with burning gas directly imparting a force on the cam surface, translated into a rotational force by timing one or more detonations. This design eliminates the multiple reciprocal pistons, ball joints and swash plate of a conventional 'barrel' engine but crucially depends on effective sealing provided by sliding and rotating surfaces. In either form the axial or 'barrel' engine can be derived as a cam engine or swashplate or wobble plate engine.

Direct Lisfranc injuries are usually caused by a crush injury, such as a heavy object falling onto the midfoot, or the foot being run over by a car or truck, or someone landing on the foot after a fall from a significant height. Indirect Lisfranc injuries are caused by a sudden rotational force on a plantar flexed (downward pointing) forefoot. Examples of this type of trauma include a rider falling from a horse but the foot remaining trapped in the stirrup, or a person falling forward after stepping into a storm drain. In athletic trauma, Lisfranc injuries occur commonly in activities such as windsurfing, kitesurfing, wakeboarding, or snowboarding (where appliance bindings pass directly over the metatarsals).

Marine Rotational Force-Darwin is a United States Marine Corps Marine Air- Ground Task Force based at Matilda Lines at Robertson Barracks and at RAAF Base Darwin. On 16 November 2011, Prime Minister Julia Gillard and President Barack Obama announced that starting in 2012 US Marines would deploy to Darwin on a rotational basis for about six months to conduct exercises and train with the Australian Defence Force in the Northern Territory. The first rotation of about 200 US Marines deployed to Australia in April 2012. On 14 June 2013, the Prime Minister announced that in 2014 the size of the deployment would increase to 1150 US Marines to be based at Robertson Barracks.

Black Sea Rotational Force began in 2010 with the purpose to form a Security Cooperation Marine Air-Ground Task Force. The forward postured troops' ability to conduct military-to-military engagements with partner nations in Eastern Europe while providing the capacity for rapid crisis response made it an essential year-round mission to U.S. European Command (EUCOM) and their partners in the Eastern European Theater. The biannual rotation of Marines and sailors with BSRF are postured in Mihail Kogălniceanu Airbase, Romania, which enables the continuation of promoting regional stability, increasing interoperability, and building and maintaining enduring partnerships with allied and partner nations. It is an outgrowth of the previous Joint Task Force East, which was planned to be a rotational brigade-sized Army force.

A load on a framework is a system of forces on the vertices (represented as vectors). A stress is a special case of a load, in which equal and opposite forces are applied to the two endpoints of each edge (which may be imagined as a spring) and the forces formed in this way are added at each vertex. Every stress is an equilibrium load, a load that does not impose any translational force on the whole system (the sum of its force vectors is zero) nor any rotational force. A linear dependence among the rows of the rigidity matrix may be represented as a self-stress, an assignment of equal and opposite forces to the endpoints of each edge that is not identically zero but that adds to zero at every vertex.

In this simple diagram of a drilling rig, #20 (in blue) is the rotary table. The kelly drive (#19) is inserted through the center of the rotary table and kelly bushings, and has free vertical (up & down) movement to allow downward force to be applied to the drill string, while the rotary table rotates it. (Note: Force is not actually applied from the top (as to push) but rather the weight is at the bottom of the drill string like a pendulum on a string.) A rotary table is a mechanical device on a drilling rig that provides clockwise (as viewed from above) rotational force to the drill string to facilitate the process of drilling a borehole. Rotary speed is the number of times the rotary table makes one full revolution in one minute (rpm).

Quality life jackets always provide more buoyancy than offered by the buoyancy aids alone.Ten newtons equals 1 kg of flotation The positioning of the buoyancy on the wearer's torso is such that a righting moment (rotational force) results that will eventually turn most persons who are floating face down in the water (for example, because they are unconscious) into a face up orientation with their bodies inclined backward, unlike more simply designed common foam buoyancy vests. Today these air chamber vests are commonly referred to as 'inflatable life jackets or vests' and are available not only for commercial applications but also for those engaged in recreational boating, fishing, sailing, kayaking and canoeing. They are available in a variety of styles and are generally more comfortable and less bulky than traditional foam vests.

They are also affected by the sun's gravity. When an asteroid or minotaur is pulled into collision with the sun, the asteroid or minotaur is destroyed and the sun expands, increasing the strength of the gravity it creates. If the sun expands beyond a certain point, a "black hole" appears, which causes the entire level to be subject to extremely strong gravity and rotational force until the level is completed. The control system of the game was unique at the time of release: rather than placing a finger continuously on the touch screen, the ship is controlled by "stroking" the screen, with each stroke applying an appropriate impulse to the ship (based on the speed, length, and duration of the stroke) and automatically rotating it to fire in the direction of the stroke.

In 2010, the first year of the program, more than 100 Marines from across the United States deployed to form a Security Cooperation Marine Air-Ground Task Force, primarily based at Romania's Mihail Kogălniceanu International Airport. Black Sea Rotational Force 13 deployed for six months from February to August 2013 as a Special Purpose Marine Air-Ground Task Force (SP-MAGTF) and consisted of almost 300 United States Marines and United States Navy sailors primarily from 2nd Battalion, 2nd Marine Regiment, 2nd Marine Division. The unit trained with 21 partner nations in the region, including Romania, Georgia, Ukraine, Bulgaria, Macedonia, Bosnia and Herzegovina, Serbia, Albania, Greece, Azerbaijan, Montenegro and Croatia. Training evolutions consisted of counterinsurgency and peacekeeping operations, communications, logistics, non-lethal weapons employment, military decision-making processes and non-commissioned officer development.

As the VII and XVIII Corps were beginning to mount the main invasion of Iraq to their far west, the Black Jack Brigade pressed into Iraq once more through the Wadi al-Batin and feinted as though they led the main invasion force. The brigade fought throughout the night and following day, fixing four Iraqi divisions and allowing the main invasion force to envelop the enemy from their west flank. With its mission an unqualified success, the Black Jack Brigade withdrew back through the Wadi al-Batin and united with the VII Corps' assaulting force to pursue and destroy the Iraqi Republican Guard in the Basra Region. In August 1995, the Black Jack Brigade deployed to Kuwait to conduct Operation Intrinsic Action 95–3, a rotational force on force training exercise.

As of January 2017 there are 3,500 troops from the 3rd Armored Brigade Combat Team, 4th Infantry Division, 87 tanks and 144 Bradley fighting vehicles there. They initially gathered first in Poland, before spreading out across seven countries from Estonia to Bulgaria. The brigade is headquartered in Germany. An armored brigade will constantly rotate deployment every nine months. The equipment will be permanently based in Żagań in western Poland alongside a Polish armored division seemingly 34th Armoured Cavalry Brigade, 11th Armoured Cavalry Division. This unit has been replaced by 2nd Brigade Combat Team, 1st Infantry Division in September 2017. AS of May 2018, the rotational force has changed to 1st Armored Brigade Combat Team, 1st Cavalry Division. 1st Armored Brigade Combat Team, 1st Infantry Division completed their rotation during October 2019 and were replaced by 2nd Armored Brigade Combat Team, 1st Cavalry Division.Spc.

Nonetheless, Neanderthals from more temperate climates—such as Iberia—still retain the "hyperarctic" physique. In 2019, English anthropologist John Stewart and colleagues suggested Neanderthals instead were adapted for sprinting because of evidence of Neanderthals preferring more warmer wooded areas over the colder mammoth steppe, and DNA analysis indicating a higher proportion of fast-twitch muscle fibres in Neanderthals than modern humans. He explained their body proportions and greater muscle mass as adaptations to sprinting as opposed to the endurance-oriented modern human physique, as persistence hunting may only be effective in hot climates where the hunter can run prey to the point of heat exhaustion (hyperthermia). They had longer heel bones, reducing their ability for endurance running, and their shorter limbs would have reduced moment arm at the limbs, allowing for greater rotational force at the wrists and ankles without extra exertion of the rotating muscles at the elbows and knees by increasing the speed at which the muscles contracted, causing faster acceleration.

As it grew, the northern boundary of the microplate most likely experienced compression due to extreme clockwise rotational force provided by the eastern shear of the Nazca Plate and the western shear of the Pacific Plate. As the Nazca plate has a close coupling to the northern boundary of the plate, rotation of the JF Microplate was at its peak during its beginning stages of formation nearing rotational speeds of 32° per Ma. However, approximately 2.5 Ma ago, the south-eastern tip of the microplate collided against a fracture zone within the Antarctic Plate thus causing compression of the microplate against the Antarctic Plate and therefore stagnating its rotational motion down to approximately 9° per Ma at approximately 1 Ma ago. The original couplings causing shear then changed from the Pacific-JF and Nazca-JF boundaries to the Atlantic-JF boundary and Nazca-JF boundaries.Engeln, J. F., S. Stein, J. Werner, and R. G. Gordon, "Microplate and shear zone models for oceanic spreading center reorganizations" J. Geophys. Res., 93, 2839–2856, 1988.
