The connection is made using a bolt and nut and two washers. If the allowable bearing stress of the washers on the boards is (σ_b)_allow= 2 ksi, and the allowable tensile stress within the bolt shank S is (σ_t)_allow= 18 ksi, determine the maximum allowable tension in the bolt shank. The bolt shank has a diameter of 0.31 in., and the washers have an outer diameter of 0.75 in. and inner diameter (hole) of 0.50 in.
