These zero terms are due to the assumptions of the classical plate theory, which assume elements normal to the mid-plane remain inextensible and line elements perpendicular to the mid-plane remain normal to the mid-plane after deformation.

Professor Frank Cotton of Sydney University, Australia, designed the world's first successful gas-operated anti-G suit. Research commenced late in 1940, and a suit was designed with rubber sacs covered externally by inextensible material. The sacs automatically inflated when G forces increased during flying. The suit was developed at the Sydney Medical School.

The theory of a disc wheel depends on their behaviour as a stressed skin structure. Their materials are assumed to be inextensible, but flexible. Such a skin is stiff against tensile loads in the plane of the skin, but flexible for loads perpendicular to it. A flat disc is thus strong for radial loads in the plane of the disc and also for torques.

He graduated in mathematics in 1901 at the University of Turin, where he was a student of Morera and of Somigliana. He taught rational mechanics at the Universities of Messina, Pavia and Padua. Laura has dealt with uncommon elasticity problems, namely related to indefinitely extended elastic means and, especially in the last part of his University career, the mechanics of flexible and inextensible surfaces.

Illustration of the Atwood machine, 1905. The Atwood machine (or Atwood's machine) was invented in 1784 by the English mathematician George Atwood as a laboratory experiment to verify the mechanical laws of motion with constant acceleration. Atwood's machine is a common classroom demonstration used to illustrate principles of classical mechanics. The ideal Atwood machine consists of two objects of mass m1 and m2, connected by an inextensible massless string over an ideal massless pulley.

This is the case where bodies are connected by an idealized cord that remains in tension and cannot change length. The constraint is that the sum of lengths of all segments of the cord is the total length, and accordingly the time derivative of this sum is zero. A dynamic problem of this type is the pendulum. Another example is a drum turned by the pull of gravity upon a falling weight attached to the rim by the inextensible cord.

ALGOL N (N for Nippon – Japan in Japanese) is the name of a successor programming language to ALGOL 60, designed in Japan with the goal of being as simple as ALGOL 60 but as powerful as ALGOL 68. The language was proposed by Nobuo Yoneda. ALGOL N tried to use extensibility to solve the problem that language designers faced when trying to make an inextensible language for all domains, or having to make many domain-specific languages (DSLs), one for each domain. It avoided type conversion (coercion) while not making things more difficult for programmers.

The free body diagrams of the two hanging masses of the Atwood machine. Our sign convention, depicted by the acceleration vectors is that m1 accelerates downward and that m2 accelerates upward, as would be the case if m1 > m2 An equation for the acceleration can be derived by analyzing forces. Assuming a massless, inextensible string and an ideal massless pulley, the only forces to consider are: tension force (T), and the weight of the two masses (W1 and W2). To find an acceleration, consider the forces affecting each individual mass.

Sidewalls are molded with manufacturer- specific detail, government mandated warning labels, and other consumer information, and sometimes decorative ornamentation, like whitewalls or tire lettering. The shoulder is that part of the tire at the edge of the tread as it makes transition to the sidewall. Plies are layers of relatively inextensible cords embedded in the rubber to hold its shape by preventing the rubber from stretching in response to the internal pressure. The orientations of the plies play a large role in the performance of the tire and is one of the main ways that tires are categorized.

Specifically, it comprises two masses (the pendulum, mass m and counterweight, mass M) connected by an inextensible, massless string suspended on two frictionless pulleys of zero radius such that the pendulum can swing freely around its pulley without colliding with the counterweight. The conventional Atwood's machine allows only "runaway" solutions (i.e. either the pendulum or counterweight eventually collides with its pulley), except for M=m. However, the swinging Atwood's machine with M>m has a large parameter space of conditions that lead to a variety of motions that can be classified as terminating or non-terminating, periodic, quasiperiodic or chaotic, bounded or unbounded, singular or non-singular due to the pendulum's reactive centrifugal force counteracting the counterweight's weight.

Expansion of the lifting gas due to solar heating is avoided in a superpressure balloon, since the inextensible PET film allows the pressure to rise as the gas is heated, rather than allow the volume to expand. This allows them to drift with, and track, horizontal atmospheric air currents at a constant air pressure level (a constant altitude) above the Earth's surface. The electronics payload was suspended below the balloon on a tether that also acted as a high frequency band radio antenna. The GHOST payload included a sun angle sensor that varied the repetition rate of its Morse code radio signal to allow technicians on the ground to locate it using an HF receiver and a set of sun angle tables.
