in a ques.. it was given dat a wire is stretched 2 double its length.v had 2 find out stress in terms of Y , new radius etc.. my first question is wether d eqn dl/l =F/AY is valid here bcoz:area is changing significantly & dl is also large.? secondly, do v calculate d new radius by using volume=constt => A 1 L 1 =A 2 L 2 or dis assumption dat volume is constt. evrytym in dis type of quesn. is wrong? pls rply.

Dear Ritika

Yea your question is correct

In the question thy asked stress

and stress =  strain* Y(youngs modulus)  [HOOK'S LAW]

dl/l =F/AY  

this one is just derived from hooke's law useing stress os F/A

from hook's you can stress

'for radius use volume constant

Please feel free to post as many doubts on our discussion forum as you can.we will get you the answer and detailed  solution very  quickly.

All the best.
