150 lb/ft 200 lb-ft 200 lb-ft A beam supports forces and moment as shown in Figure. The reactions at A and B are shown in figure as well. (A) Define the loading function q(x) using Singularity functions, and determine the shear and moment functions. (B) Sketch the shear force and bending moment diagrams, and find the maximum absolute value of bending moment, Mmax- 4 ft. -x- 450 lb 6 ft B 450 lb 4 ft
