1. The cross section of the rectangular ring in Figure P11.15 is 12 in. × 8 in. Draw the moment and shear curves for the ring; E = 3000 kips/in.2.
2. Analyze the frame in Figure P11.16 by moment distribution. Determine all reactions and draw the shear and moment curves locating points of inflection and labeling values of maximum shear and moment in each span. E is constant, but I varies as indicated below.
