Question: A laminated wood beam is built up by gluing together three 2- in.-by-4-in. members to form a solid beam 4-in.-by-6-in. in cross section, as shown. The allowable shear stress in the glued joints is 60 psi. The beam is a 3-ft-long cantilever with a load P applied at its free end. Neglecting the weight of the beam:
