Question: 1. The truss in Figure P3.30 is composed of pinjointed members that carry only axial load. Determine the forces in members, a, b, and c by passing vertical section 1-1 through the center of the truss.
2. (a) In Figure P3.31 trusses 1 and 2 are stable elements that can be treated as rigid bodies. Compute all reactions.
(b) Draw free-body diagrams of each truss and evaluate the forces applied to the trusses at joints C, B, and D.
