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

Suppose a 1/4 × 10 in. plate is formed into a channel section 6 in. high with flanges top and bottom estimated at 2 1/4 in. wide. If the resulting member is to be used in bending about the y-axis, find the values for and Iy if the equations of Fig. 1-7 can be assumed applicable.
