Beam A BCD is used to support a machine tool. The beam weighs 60 lb/ft of length, and the machine weighs 1200 lb with center of gravity at point E. Assuming the ma­chine applies only vertical forces to the beam at points B and C. determine the shear and moment within beam A BCD as functions of position, and draw the shear and mo­ment diagrams.
