A laminated wood beam consists of eight 1.75 in. x 5.00-in. planks glued together to form a section b = 5.00 in. wide by d = 14 in. deep, as shown. If the allowable strength of the glue in shear is 130 psi, determine (a) the maximum uniformly distributed load w that can be applied over the full length of the beam if the beam is simply supported and has a span of L = 30 ft. (b) the shear stress in the glue joint at H, which is located 3.5 in. above the bottom of the beam and at a distance of x = 128 in. from the left support. Assume that the beam is subjected to the load w determined in part (a). (c) the maximum tension bending stress in the beam when the load of part (a) is applied. W L B t 1 (typ.) Z H y b
