A laminated wood beam consists of eight 2.25 in. × 5.00-in. planks glued together to form a section b = 5.00 in. wide by d = 18 in. deep, as shown and w = 663.2 lb/ft. If the allowable strength of the glue in shear is 105 psi, Determine:(b) the shear stress in the glue joint at H, which is located 4.5 in. above the bottom of the beam and at a distance of x = 86 in. from the left support. Assume that the beam is subjected to the load w determined in part (a). [Answer: τH = 19.34 psi]
