Problem$-3$:$(15$ points$)$

A$)$ In the figure, shaft C is stationary. If gear $2$ rotates at $800re\frac{v}{m}$inCCW, what is the speed and direction of rotation of shaft B$?$

B$)$ In the figure, consider shaft B as stationary. If shaft C is driven at $380re\frac{v}{m}$inCCW, what is the speed and direction of rotation of shaft A$?$

C$)$ In the figure, determine the speed and direction of rotation of shaft $C$ if shafts A and $B$ both rotate at $360re\frac{v}{m}$inccw.
