Question:
A beam is fabricated by gluing four dimension lumber boards, each 40 mm wide and 90 mm deep, to a plywood web as shown in Figure P9.45. Determine the maximum allowable shear force and the maximum allowable bending moment that this section can carry if the allowable bending stress is 6 MPa, the allowable shear stress in the plywood is 640 kPa, and the allowable shear stress in the glued joints is 250 kPa.
