$19\mathrm{.}1$ Compute the allowable tensile load for the single$-$shear lap joint shown. The plates are ASTM A$36$ steel and the high$-$strength bolts are $\frac{7}{8}-$in$.-$diameter A$325$ bolts in standard holes. Assume a bearing$-$type connection with threads excluded from the shear plane $($A$325-$X$).$ Problem $19\mathrm{.}1$
