Required information

The solid spindle $AB$ has a diameter $d_S=1\mathrm{.}72in.$ and is made of a steel with $G=11\mathrm{.}2{10}^6$ and ${}_{\text{a}\text{l}\text{l}}=12$ksi, while sleeve

$CD$ is made of a brass with $G=5\mathrm{.}6{10}^6$ and ${}_{\text{a}\text{l}\text{l}}=7$ksi.

NOTE: This is a multi$-$part question. Once an answer is submitted, you will be unable to return to this part.

Determine the largest torque $T$ that can be applied at $A$ if the given allowable stresses are not to be exceeded and if the angle of twist

of sleeve $CD$ is not to exceed $0\mathrm{.}375.$

The largest torque $T$ that can be applied at $A$ is

kip.in$.$
