Determine the angle of twist in shaft (2). $\begin{array}{l}?0.16432\mathrm{rad}\\ ?0.10154\mathrm{rad}\\ ?0.22806\mathrm{rad}\\ ?0.10824\mathrm{rad}\\ ?0.06268\mathrm{rad}\end{array}$ Determine the rotation angle of $C$ with respect to the support at $A$. $\begin{array}{c}?0.0043\mathrm{rad}\\ ?0.0029\mathrm{rad}\\ ?0.0058\mathrm{rad}\\ ?0.0077\mathrm{rad}\\ ?0.005\mathrm{rad}\end{array}$ The compound shaft shown in the figure consists of an aluminum segment (1) and a steel segment (2). Aluminum segment (1) is a tube with an outside diameter of $D_1=3.5\mathrm{in}$., a wall thickness of $t_1=0.25$ in., and a shear modulus of $G_1$ $=3600\mathrm{ksi}$. Steel segment (2) is a tube with an outside diameter of $D_2=2.1\mathrm{in}$., a wall thickness of $t_2=0.125\mathrm{in}$., and a shear modulus of $G_2=11800\mathrm{ksi}$. The compound shaft is subjected to torques applied at $\mathrm{B}$ and $\mathrm{C}$ as shown in the figure. $L_1=9\mathrm{ft},L_2=6\mathrm{ft},T_B=1750\mathrm{lb}.\mathrm{ft},T_C=650\mathrm{lb}.\mathrm{ft}]$ Determine the angle of twist in shaft (1). $0.0584\mathrm{rad}$ $0.0483\mathrm{rad}$ $0.0812\mathrm{rad}$ 0.0643 rad $0.0244\mathrm{rad}$
