(a) Use the equilibrium approach to determine the shear as a function of position in the region 0 ≤ x ≤ 4 ft.

(b) Use the integration approach with the results of Part (a) to determine the moment in the region 0 ≤ x ≤ 4 ft.

(c) Values for shear and moment just to the right of B and at C are shown in the shear and moment diagrams provided. By inspection, complete these diagrams. Accurately draw the shapes of the curves, and label the slopes at x = 4 ft, and x = 12 ft.
