For the simply supported beam subjected to the loading shown in Figure P7.7,

(a) derive equations for the shear force V and the bending moment M for any location in the beam. (Place the origin at point A.)

(b) plot the shear-force and bending-moment diagrams for the beam, using the derived functions.
