PROBLEM SET #2 METHOD OF JOINTS 1. Determine the force in each member of the truss shown. State whether each member is in tension or compression. Solve also for the components of the reactions at the supports. (Start at jt. A) A 350 4 m E B 35° 4 m 1.5P C 55° D OXOXO
Determine the forces in members EF and GI of the truss shown. 28 kips 28 kips C E K 16 kips 10 ft D F H 8 ft 8 ft 8 ft8 ft 8 ft STRATEGY: You are asked to determine the forces in only two of the members in this truss, so the method of sections is more appropriate than the method of joints. You can use a free-body diagram of the entire truss to help determine the reactions, and then pass sections through the truss to isolate parts of it for calculating the desired forces.
