Homework Help: Magnitude of Cable Tensions and Compressive Force

  1. Sep 12, 2012 #1
    1. The problem statement, all variables and given/known data

    There's a diagram with a rough free body diagram implemented.

    2. Relevant equations

    This is what I'm really unsure about.

    3. The attempt at a solution

    Finding Compression at BC: mg*sin(60) = 8495N
    Tension AC = mg*cos(25) = 8890N

    Not sure if that's right, but, it's all I can come up with!

    Please help!!

    At point C, what is the direction of:

    1. The reaction force of the beam?
    2. The reaction force of the upper part of the cable?
    3. The force applied by the lower part of the cable?

    How do I find them?

    Each of those has only two possibilities. Consider both, choose one that makes physical sense.
