Why is length independent of young modulus ?

  1. Apr 5, 2016 #1
    If young modulus = stress/strain
    Wouldn't a different original length affect the value of young modulus ?

    Where does original length figure in the definition or formula for YM?

    With a different original length, there will also be a different change in length, so the ratio of the change in length to the original length stays the same.
