The bar is connected to the support using a pin having a diameter of

$d=1$ in$.$ The allowable tensile stress for the bar is

$({}_t{)}_{\text{a}\text{l}\text{l}\text{o}\text{w}}=22$ksi, and the allowable bearing stress between the

pin and the bar is $({}_b{)}_{\text{a}\text{l}\text{l}\text{o}\text{w}}=28$ksi. Assume the hole in the bar

has the same diameter as the pin. $($Figure $1)$
