$2-$ The solid spindle $AB$ has a diameter $d_s=1\mathrm{.}81in.$ and is made of steel with $G=11\mathrm{.}2{10}^6$ and ${}_{\text{a}\text{l}\text{l}}=12$ksi, while sleeve $CD$ is made of brass with $G=5\mathrm{.}6{10}^6$ and ${}_{\text{a}\text{l}\text{l}}=7$ksi. 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 $0\mathrm{.}375.$ Answer: $T=13\mathrm{.}97$
