Learning Goal: applicable torque given a maximum allowable angle of twist.

External torques are applied to the rod at point $B$ and point $C.$ Let $L_A=54\mathrm{.}0$ in$,L_B=47\mathrm{.}0in,d_A=3\mathrm{.}9in,d_B=2\mathrm{.}3in,T_B=6\mathrm{.}0$kip $-$ in$,$ and $T_C=11\mathrm{.}0$kip$*$ in $.$

Part A $-$ Angle of twist at point $B$

Determine the angle of twist, ${}_B,$ experienced by the rod at point $B.$

Express your answer to three significant figures and include appropriate units.

Vlew Avallable Hint$($s$)$

${}_B=$

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

Determine the angle of twist, $$C

$,$ experienced by the rod at point C

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