Question

For the beam shown,

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

(2) use the derived functions to plot the shear-force and bending-moment diagrams for the beam. Specify the values for key points on the diagrams.

Let a=7.0 ft, b=8.7 ft, w_a=13 kips/ft, and w_b=7 kips/ft.
