The answer is 3375N/m
5.76 The laminated beam, shown in cross section, is composed of five 150 mm by 50 mm planks that are glued together. The beam carries a uniformly distributed load of intensity wo over its 2.5-m simply supported span. If the working stresses are 0.5 MPa for shear in glue, 0.8 MPa for shear in wood, and 10 MPa for bending in wood, determine the maximum allowable value of wo.
