Young's Modulus of guitar string

  1. Nov 9, 2013 #1
    1. The problem statement, all variables and given/known data

    A guitar string of diameter 0.6 mm and length 0.82 m is subject to a tension of 153 N. If the string stretches an amount 0.36 mm, what is Young's modulus of the string?

    2. Relevant equations

    Y=Stress/Strain
    Stress=F/A
    Strain=Amount of stress/Original Length

    3. The attempt at a solution

    Stress=153/(pi*(0.0003^2)
    Strain= 0.00036/0.82

    I converted all the units to meters, but it is still not right and I'm not sure what I'm doing wrong.

    What is not right? And how do you know it?

    There is an unmatched parentheses on your calculation for stress, but other than that nothing appears to be wrong.
