Young Modulus calculation

  1. Aug 2, 2010 #1
    Hi I have a problem with the following question:

    A steel violin string has a cross-sectional area of 0.2*10^-6 m^2 and is under tension 83N. If its length under tension is 35cm, find its original length.

    I can not seem to solve the question without needing the value of young modulus...

    That's correct, so look up Young's modulus for steel, the given material. It varies a bit amongst different grades of steels, but not by much.

    Hi :)

    I am supposed to find it using only the given information. Therefore I can not use Young's Modulus.
