 P: 8 1. The problem statement, all variables and given/known data please see the image, I am supposed to find the internal force in each member of the truss and state if its in compression or tension 2. Relevant equations 3. The attempt at a solution here is what I have so far (all in kN).... My=40 up Gy=80 up Mx=0 from joint G Tga=100 in compression Tgh=60 in tension from joint A Tah=90 in compression Tab=80 in tension from joint H Thb=162.5 in tension Thj=157.5 in compression from joint J Tjb=20 in tension Tjk=157.5 in tension from joint B Tbk=162.5 in tension Tbc=80 in compression from joint K Tkl=255 in compression I stopped here, I feel I've done something wrong, can someone let me know if I'm doing something wrong.....thanks Attached Thumbnails
