About Spring

A spring is a mechanical element that uses elasticity. The property of a material that expands or contracts when a force is applied and returns to its original shape when the force is removed is called elasticity. Springs are used in various places and parts, such as functions as cushions that soften shocks, functions to restore position using the force of returning to the original state, and functions as instruments such as spring measurement. In addition to coil-shaped springs, there are also rod-shaped springs and plate-shaped springs.
