G$=36\mathrm{.}4$GPa G$=21\mathrm{.}2$GPa tube. Aluminum tube $(1)$ has an outside diameter of $98$ mm $,$ an inside diameter of $74$ mm $,$ and a length

of $0\mathrm{.}52$ m $.$ Both the brass shaft and the aluminum tube are securely attached to the wall support at A$.$ Assume L$\_(1)=$L$\_(2)=0\mathrm{.}52$m$,$L$\_(3)=0\mathrm{.}48$

m$,$T$\_($B$)=26$kN$-$m$,$ and T$\_($C$)=8$kN$-$m$.$ When the two torques shown are applied to the composite shaft, determine:

$($a$)$ the maximum shear stress magnitude $\backslash$tau $\_(1)$ in aluminum tube $(1).$

$($b$)$ the maximum shear stress magnitude $\backslash$tau $\_(2)$ in brass shaft segment $(2).$

$($c$)$ the maximum shear stress magnitude $\backslash$tau $\_(3)$ in brass shaft segment $(3).$

$($d$)$ the rotation angle $\backslash$phi $\_($B$)$ of joint B$.$

$($e$)$ the rotation angle $\backslash$phi $\_($C$)$ of joint C$.$
