please see the attached image, I'm supposed to find the internal force in each member of the truss.
I used moments to find My=40 and Gy=120, I then moved on to FBD of joint G where I found Fgh=30kN in tension, and Fga=50kN in compression, next I did joint A to find Fab=30kN in tension and Fah=60kN in compression...I'm stuck on joint H, I have too many unknowns for my equations...I also get confused with the signs in this problems, any help is greatly appreciated...
also, please let me know if I'm wrong on any of my values...thanks
