The compound wooden beam is connected together by a bolt at B as shown in (Figure 1). Assume that the connections at A, B, C, and D exert only vertical forces on the members. The allowable tensile stress for the bolt is (?t)allow(?t)allow = 180 MPa and the allowable bearing stress for the wood is (?b)allow(?b)allow = 32 MPa. Assume that the hole in the washers has the same diameter as the bolt.
