1. Homework Statement
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.

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.
