Torsion spring - Wikipedia

A torsion spring is a spring that works by twisting its end along its axis; that is, a flexible elastic object that stores mechanical energy when it is twisted. When it is twisted, it exerts a torque in the opposite direction, proportional to the amount (angle) it is twisted. There are various types: A torsion bar is a straight bar of metal or rubber that is subjected to twisting (shear stress ...

Series and parallel springs - Wikipedia

More generally, two or more springs are in series when any external stress applied to the ensemble gets applied to each spring without change of magnitude, and the amount strain (deformation) of the ensemble is the sum of the strains of the individual springs. Conversely, they are said to be in parallel if the strain of the ensemble is their common strain, and the stress of the ensemble is the ...

Spring Framework - Wikipedia

The Spring Framework is an application framework and inversion of control container for the Java platform.

Garter spring - Wikipedia

Extension Springs. Extension garter springs are on the opposite side of the spring spectrum. Although they are also a type of coiled spring, extension garter springs exert inward radial forces that move toward the center.

Hooke's law - Wikipedia

Hooke's law is a law of physics that states that the force (F) needed to extend or compress a spring by some distance x scales linearly with respect to that distance. That is: =, where k is a constant factor characteristic of the spring: its stiffness, and x is small compared to the total possible deformation of the spring. The law is named after 17th-century British physicist Robert Hooke.

About Extension Springs - ThomasNet

Extension springs are tightly coiled springs designed to resist a tensile, or stretching, force. When pulled outward, the spring will attempt to pull back into its coil. As the spring is extended further, its resistance increases. This means that extension springs exert a greater pull the wider their ends are extended.
