L$\_($B$)=41\mathrm{.}0$ in $,$ d$\_($A$)=3\mathrm{.}2$in$,$d$\_($B$)=2\mathrm{.}0$in$,$T$\_($B$)=10\mathrm{.}0$kip$*$in$,$ and T$\_($C$)=18\mathrm{.}0$kip$*$in

a$)$ Determine the angle of twist, $$B$,$ experienced by the rod at point B$.$

b$)$ Determine the angle of twist, $$C$,$ experienced by the rod at point C$.$

c$)$ Determine the angle of twist, $$C$,$ experienced by the rod at point C if the segment BC is solid rather than hollow.
