Help drawing a FBD for the question

  1. Oct 2, 2011 #1
    1. The problem statement, all variables and given/known data
    A person is holding onto 2 separate rings and each at angle is 85 degrees. find the tension in each rope. The mass of the person is 70kg. so we know the mass of the person, and the angle of ropes, i should be able to figure it out by looking at a FBD but i don't know how the FBD would look. i just need to know what points should be taken as the square (or the dot) in the FBD, the areas where his hands meet the rings or the areas where the rope attaches to the roof

    2. Relevant equations

    3. The attempt at a solution
