The shaft is driven by torque, $T,$ which is applied at $C,$ to drive the gear and produce gear forces, Fg$.3\mathrm{.}2(10)$ Find the maximum bending moment in the shaft at $B$ due to the bearing reactions at $C.$

$3\mathrm{.}1(15)$ Find reactions Rcx$,$ Rcy$,$ and Rcz at bearing C$.$ Bearing $C$ is not "fixed" for axial displacement, but bearing A is "fixed" for axial displacement.

$Rcx$:$=0,$ lbf$,$ reaction at C in x $-$direction is zero since bearing C is not "fixed".
