How to find cord tension and hinge force?

  1. Oct 28, 2014 #1
    1. The problem statement, all variables and given/known data
    A 5 kg 10 m beam is hanging from a wall. The angle between the cord and the wall is 30 degrees, and a 10kg mass is situated one meter away from the wall. How do I solve for cord tension and hinge force?

    2. Relevant equations

    3. The attempt at a solution
    it says the answers are 69N and 130N for tension and force respectively.

    Draw a free body diagram of the beam and the cord, with the weight attached to the beam.

    Write equations of static equilibrium for the free body so that you can determine the unknown tension and the hinge force.
