The connection is made using a bolt and nut and two washers. If the allowable bearing stress of the washers on the boards is $${\left({?}_b\right)}_{\text{allow }}=3\mathrm{ksi}$$, and the allowable tensile stress within the bolt shank S is $${\left({?}_t\right)}_{\text{allow }}=20\mathrm{ksi}$$, determine the maximum allowable tension in the bolt shank. The bolt shank has a diameter of $$0.35$$ in., and the washers have an outer diameter of $$0.6$$ in. and inner diameter (hole) of $$0.4in.$$
