Homework Help: As physics stress/strain

  1. Nov 13, 2008 #1
    1. we have been using σ=F/A (stress=force/area) and we have done an experement striching a spring and completing a force/extention graph, we have been told to create a stress/strain graph and i couldn't work out how to get the cross sectional area of the spring... and ive been told that there was a deliberate mistake.
    please help!?

    2. σ=F/A, ε=∆x/l

    Normally you would plot force against strain and so the stress would be in arbitrary units of force/sping area.
