Question

The stress required to double the length of a wire of young's modulus​

Answer 1

Answer:

Hope it helps plzz mark as brainlist and like it

Explanation:

Young's modulus, E =

strain

stress

Where, strain=

original length

change in length

Let the initial length of the wire be x m.

Thus change in length =2x−x=x

Original length =x

So, strain = 1

So, we get E= stress/1
