A box beam is fabricated from two plywood webs that are secured to dimension lumber boards at its top and bottom flanges. The beam supports a concentrated load of P = 5675 lb at the center of a 15-ft span. Bolts (3/8-in. diameter) connect the plywood webs and the lumber flanges at a spacing of s = 8 in. along the span. Supports A and C can be idealized as a pin and a roller, respectively. Determine the average shear stress in the bolts. 4 in. Plywood webs O. O. 16 in. O. A B 4 in. 0.5 in. 0.5 in. 3 in.
