2. A structure consisting of two beams is built up as shown. Bar AC is horizontal, Bar BC is oriented 32 with respect to the horizontal direction. The beams have masses mc-50kg and mc 30 kg that act at the center of gravity of each beam (at mid-length). Points A, B and C are pin connectors. (a) Draw a FBD of bar BC and place all relevant loads. 200 N-m A B 25 N CG 32 0.35m 75 N 100 N 0.35m 400 N
