The spring is an elastic object that stores mechanical energy. Springs are usually made of spring steel, and there are many different types of springs. Commonly, coil springs are the type used in everyday life.

What Is an Extension Spring?

An extension spring is a device used to store and exert force between two mechanisms. When the two mechanisms separate, the extension spring tries to bring them back together again. Extension springs are constructed using round wire to create a close-wound design with an initial tension.

How Extension Springs Work?

There are two mechanisms attached to the ends of an extension spring. The hooks and loops of the spring store and absorb energy. Through these hooks and loops, the extension spring provides return force to the mechanisms connected to it.

There is more stress in the end hooks of an extension spring that sits in the no-load position since they are wrapped tightly. This more stress affects the performance of extension springs rather than the spring bodies.
