Question

(16 points) Difficulty (3/5) A simply-supported beam is subjected to a coupled moment C = 480 ft-lb and the forces F1 = 530 lb and F2 = 720 lb. The dimensions of the beam are: a = 7.9 ft b = 4.7 ft C = 4.6 ft d = 4.6 ft Determine the shearing force and bending moment at the following locations. Lub c d At 21 = 4.9 ft (from the left support) V.1 = M1 = At 12 = 10.2 ft (from the left support) V12 = Mz2 = At 13 = 13.3 ft (from the left support) M23 = At 24 = 18.6 ft (from the left support) Vz4 M4= be sure to include units with your answers Note: You can earn partial credit on this problem.
