How do I calculate the extension and strain at peak load?

  1. Aug 19, 2016 #1
    1. The problem statement, all variables and given/known data

    If a question gives us a max load with different extensions, how do I calculate the strain?

    For example:

    1900KN=x mm
    1900KN=x mm
    2000KN=x mm
    2000KN=x mm
    2000KN=x mm
    1900KN=x mm
    1900KN=x mm

    2. Relevant equations

    strain= ΔL / L

    3. The attempt at a solution

    What I think is perhaps taking the average extension x? Is this correct? And afterwards taking x avg/ L?

    Not a very specific/clear question. Would the max load be 2 MegaNewton ?
    If you have the ##\Delta x## and the ##\Delta F##, you have the slope of the stress/strain curve, don't you ?
    You do want to check that you are in the linear range, but perhaps that's assured by the term 'max load'.
