Young's Modulus Question

  1. Feb 19, 2008 #1
    I seem to be going a bit brain dead here, but in youngs modulus, how are the units in GPa as they are in one of my product specs I've just received?

    Lets say we have stress in kN/m^2 and strain has no units, then surely E should be in kN/m^2?

    Pressure is measured in Pascals, and Pressure is defined as a force per unit area. So, a Pascal is really one Newton per unit area: N/m^2, for instance. So, kN/m^2 = kPa, which of course is just 10^6 GPa.

    Doh.

    Thanks!
