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.
