  1. Dec 10, 2017 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations
    deformation=(force*length)/(elastic moduli*area)

    3. The attempt at a solution

    and

    since most of the variable are constants it seemed like a simple plug in problem, however it seems that my use of the forces is incorrect. unfortunately we had no examples for this chapter in class and what is in the textbook has not helped me so far. the above is both equations for deformation of each rod summed together top rod first then bottom.

    From an overall force balance, what is the reaction force at A? What is the tension in AB? What is the tension in BC?
