Problem $2(25$ pts$)$

Version A

The solid composite shaft consists of a titanium segment $AC$ and an aluminum segment $CB,$ has a diameter $d=44$ mm $,$ and is rigidly attached to a wall at $A.$ If $F=14kN$ and $T=800N*m,$ determine the maximum shear stresses in segments $AC$ and $CB,$ and the angle of twist of end $B.$ Use $G_{Ti}=44$GPa and $G_{Al}=27$GPa.
