Q/1 A hollow box beam ABCD is supported at A by a pin that passes through the beam as shown in the figure. The beam is also supported by a roller located at B. The beam dimensions are a = 2.5 ft, b = 5.5 ft, and c = 3.5 ft. Two equal concentrated loads of P 2,750 lb are placed on the beam at points C and D. The beam has a wall thickness t= 0.375 in., and the pin at A has a diameter of 0.750 in. Determine: (a) the average shear stress in the pin at A. (b) the average bearing stress in the box beam at A.
