Problem 3 (20 points) A design concept for a truss member is shown below including two $\mathrm{C}12\times 25$ sections connected to a 1-in gusset plate. How many 7/8-in A325 bolts (threads excluded from shear plane) are required to develop the full tensile capacity of the member if it is used as a bearing type connection? Assume $\mathrm{U}=0.85$, A36 steel, and do not check block-shear. Show detailed calculations.
