How do you work out Young's Modulus?

  1. Oct 31, 2012 #1
    I am really finding it hard to work out Young's Modulus.

    I have my stress / strain graph

    I was told I should apply a gradient on the graph to work out youngs modulus

    The strain is in (m) and the stress is in (nm-2)

    How do I work out the youngs modulus, and what unit of measurement would youngs modulus be in?

    Look in Wikipedia. It's a good explanation.
