As we know that stress is equals to young's modulars multiplied by strain.
00:09
Now stress can be written as force divided by area is equal to young's modulars multiplied by the strain can be written as delta l change in length divided by original length.
00:22
But from here we get change in length is equals to force multiplied by length divided area multiplied by yonge's modular.

Let this equation be equation number 1.

Now, from this, we can write the change in length of the left wire, delta ll, is equals to force in left wire, length of left wire, divided by area of left wire, will be pi r left square multiplied by yonks modulus.

Similarly, change in length of the right wire is equals to force in right wire, length of right wire, divided area of right wire that is pi, radius of right wire is square multiplied by yonge modulus...
