Beams ABC and CD are supported at A, C, and D and are joined by a hinge (or moment release) just to the left of C. The support at A is a sliding support (hence reaction A_y
= 0 for the loading shown below). Find all support reactions; then plot shear (V) and moment (M) diagrams. Label all critical V and M values and also the distance to points where either V and/or M are zero.
