Question

Derive a formula for work done in pulling a wire.​

Answer 1

Answer:

In stretching a wire work is done against internal restoring forces. This work is stored as elastic potential energy or strain energy.

Answer 2

$\huge\sf\underline{Answer}:$

Explanation:

In stretching a wire work is done against internal restoring forces. This work is stored as elastic potential energy or strain energy.

Scientifically Work done formula will be given as, W = F × d: In this case, the force exerting on the block is constant, but the direction of force and direction of displacement influenced by this force is different.

Let's start with the derivation of the above equation. Let the spring be stretched through a small distance d x dx dx. Then work done in stretching the spring through a distance d x dx dx is d W = F d x , dW=Fdx, dW=Fdx, where F is the force applied to stretch the spring.
