A beam with rigid support at A, pin connection at C and roller at D has the geometry and loads as shown
in the figure and parameter table. Find the equations for the shear and moment as a function of a in each
segment of the beam.
Follow the sign convention that positive shear tends to rotate the object clockwise, and a positive moment
would tend to bend the object concave up. Take the origin for all functions to be at A.
