A laminated beam is composed of 3 plants, each 150 mm x 60mm, glued together to form a section 150mm wide by 180 mm high. The allowable shear stress of the wood is 900 kPa and that of the glue is 600 kPa. The allowable bending stress is 8 MPa. What maximum magnitude of a uniformly distributed loading (W) can the beam safely support at a span of 2 meters?
