The steel frame below is loaded as shown. The corners B and C are rigidly connected. The supports at A and D can be idealized as a rocker and a pin, respectively. Determine (1) the intensity of the distributed load, w (k-ft) and the support
reactions at A and D, when point E of the frame is found to have developed an internal positive moment of 62 k-ft. Then (2) plot the shear force and bending moment diagrams of member B-C of the frame.
