Question

Derive an expression for energy stored in a stretched spring .​

Answer 1

Answer:

The characteristic of a spring is that the force needed to stretch or compress a spring by an amount x is equal to k x and is in the direction opposite to the extension or compression. Here k is called the spring constant.

 

     Restoration Force of the spring (compression or tensile) Fs = - k x  = - external force F

 

     Work done by the external force in compressing the spring from x = 0 to x = L can be obtained by:

 is the energy given by the external force to the spring with an extension x. 

This energy is stored as potential energy in the

Answer 2

Hie sugar...xD

Explanation:

Here k is called the spring constant. Work done by the external force in compressing the spring from x = 0 to x = L can be obtained by: is the energy given by the external force to the spring with an extension x. This energy is stored as potential energy in the spring.
