The strut AB made from two bars (thickness of each bar = 0.50 in) is connected to a rectangular beam CD (b = 0.80 in x h = 7.5 in) at joint B. The beam carries a concentrated load of 2750 lb at the end joint D. (a) determine the minimum diameter of the bolt at B if the shearing stress in the bolt is not to exceed 14000 psi. (b) determine the minimum diameter of the bolt at B if the allowable bearing stress in the bar plate is 20000 psi. (Please provide detailed solution with FBD,thank you) ( a ) d = ? in ( b ) d = ? in
