The shaft is made from a solid steel section $AB$ and a tubular portion

made of steel and having a brass core. It is fixed to a rigid support at $A,$

and a torque of $T=50lb*ft$ is applied to it at $C.$ Take

$G_{st}=11\mathrm{.}5({10}^3)ksi,G_{br}=5\mathrm{.}6({10}^3)ksi($Figure $1)$

Part A

Determine the magnitude of the angle of twist that occurs at $C.$

Express your answer in degrees to three significant figures.

Part B
