(a) Evaluate the reactions and construct the moment diagram for the beam in Figure 5.25a by superposition of the reactions and moment curves associated with the individual loads in parts (b), (c), and (d). 

(b) Calculate the moment of the area under the moment diagram between the left support and the center of the beam with respect to an axis through support A.
