The laminated beam, shown in cross section, is composed of ?ve 6- in. by 2-in. planks that are glued together. The beam carries a uniformly distributed load of intensity we over its 8-ft simply supported span. glue, 90 psi for shear in wood, and 800 psi for bending in wood, If the working stresses are 75 psi for shear in 6 in. 1. determine the maximum allowable value of we so that the shear stress in the wood is not exceeded.

The diameter of the bent bar is 1/4" Ø, outside diameter of the washer is 7/8" Ø and the thickness of the fiber glass is 3/8". The working shear stress between the fiberglass and the washer is 300 psi, and the allowable bearing pressure between the washer and the fiberglass is 550 psi.
