A solid circular steel shaft ${1\mathrm{.}5}^{\text{'}\text{'}}$ inches in diameter is ${60}^{\text{'}\text{'}}$ long. The allowable shear stress is $12$ ksi $($ allow $=12$ksi $).$

The allowable rotation at end $B$ is $0\mathrm{.}1$ rad $({}_{\text{a}\text{l}\text{l}\text{o}\text{w}}=0\mathrm{.}1$rad $).$

Determine the allowable applied torque, $T.$

$E_S=29{10}^3$ksi

$G_S=12{10}^3$ksi. Please answer thoroughly... studying for a final!
