Calculate stress, strain & YME

  1. Feb 11, 2007 #1
    Appreciate if someone can take the time to check my answers to the following question. If wrong, could you point me in the right direction.

    A round bar, 800 mm long, CSA 15 mm^2 experiences an applied tensile load of 6 kN and stretches elastically by 3 mm.


    a) Calculate the tensile stress in the bar.
    My answer 400 MN/m^2

    b) Calculate the strain on the rod.
    My answer 0.00375 or 0.375%

    c) Calculate the Modulus of Elasticity of the material.
    My answer 106.67 GN/m^2

    The answers look correct, except I set the units up different, but the numbers seem okay.
