Problem 1.9-3 A horizontal beam AB with cross-sectional dimensions (b-0.75 in.) X (h-8.0 in.) is supported by an inclined strut CD and carries a load P-2700 lb at joint B [see figure part (a)]. The strut, which consists of two bars each of thickness 5b/8, is connected to the beam by a bolt passing through the three bars meeting at joint C Isee figure part (b)J. (a) If the allowable shear stress in the bolt is 13,000 psi, what is the minimum required diameter dein of the bolt at C? (b) If the allowable bearing stress in the bolt is 19,000 psi, what is the minimum required diameter d of the bolt at C? 5 ft 3 ft D.
