How can I know which enters yield bar first?

  1. Apr 19, 2015 #1
    1. The problem statement, all variables and given/known data

    upload_2015-4-19_17-30-22.png
    2. Relevant equations

    Area AD = Area BE

    E(AD) =E (BE)

    Yield stress = 250 MPa


    3. The attempt at a solution

    Delta= PL/(AE) if in both bars the A and E are the same, and from the equilibrium I get Q= 4.125 F(AD) + F(BE) , also from the compatibility I get delta AD = 4.125 delta BE

    How can I know which bar (AD or BE) reach the yield first??

    Or how can I know which bar will reach a perfectly plastic behavior first?

    @Queren Suriano, you didn't include a statement of the problem, so we have no idea what you're trying to do or what the symbols mean. AD looks like it would be a line segement, but what is Area AD? And what is E(AD)? What is a yield bar? You have not provided enough information for us to be able to help you.
