The truss shown is pinned at A and has a roller at F and is loaded with a force, F_(1)=333lb,F_(2)=252lb, and
F_(3)=511lb, and the dimension, a=34ft, and b=26ft.
a. Determine the zero force members in the truss.
b. Determine the support reaction(s) at G
c. Determine the force in member IK
d. Determine the force in member DI
e. Determine the force in member DE
