From the gear reducer, which has a pressure angle $=18,$ the input and output shafts $AB$ and $CD$ are rotating at constant speeds $i$ and $0,$ respectively. The input and output torques $($torque moments$)$

are $Ti=240lb-$in and To $,$ respectively. The shafts are supported in the housing by ball bearings at $A,B,C,$ and

D$.$ The pitch radii of the gears G$1$ and G$2$ are $r1=0\mathrm{.}75$ in and $r2=1\mathrm{.}5$ in$,$ respectively. Draw free$-$body

diagrams for each member and determine the net reaction forces and moments occurring at all points.
