A coil spring is a mechanical device which is typically used to store energy and then release it, to absorb shock, or to maintain a force between contacting surfaces. They are made of elastic material that forms a spiral shape and returns to its natural length when unloaded. Under tension or compression, the material (wire) of a coil spring is subjected to twisting. Therefore, the spring properties depend on the shear modulus, not on the Young's modulus.
