Draw and dimension the load and reaction diagram, the shear diagram, and the bending moment diagram for the beams shown in the following figures:

The casting shown in section in Fig. 1 has its center of gravity located as shown. Assume that all loads can be considered as acting at the center of the 75 mm bearing. Find the value of the bending stress for this point.
