Truss analysis

  1. May 10, 2016 #1
    1. The problem statement, all variables and given/known data
    I solved for all the forces in the members, but I was using a force truss member calculator to check my work. All the forces match up with the calculated but one, that is the force in member GH. I get 11.3 in tension the calculator gets 6 in tension. So am I right or the calculator? I attached the diagram. The load is 12.5 and is applied at joint C. There is a roller at joint I and a hinge at joint F. Can someone solve for member GH and tell me what they get.

    2. Relevant equations


    3. The attempt at a solution

    Your answer looks about right. What force did you get in AG? If the calculator is messed, I wouldn't compare your answers to it for any member.
