Pls help. A laminated wood beam consists of eight 2 in. × 7.00-in. planks glued together to form a section b = 7.00 in. wide by d = 16 in. deep, as shown. If the allowable strength of the glue in shear is 135 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 = 21 ft. (b) the shear stress in the glue joint at H, which is located 4 in. above the bottom of the beam and at a distance of x = 76 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.

A laminated wood beam consists of eight 2 in. × 7.00-in. planks glued together to form a section b = 7.00 in. wide by d = 16 in. deep, as shown. If the allowable strength of the glue in shear is 135 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 = 21 ft.
(b) the shear stress in the glue joint at H, which is located 4 in. above the bottom of the beam and at a distance of x = 76 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.
