PLEASE KEEP ALL UNITS IN U$.$S$.$ STANDARD UNITS $($lb$,$ in$,$ hp$,$ lb$-$in$)$

I also need help with making a shear and moment diagram for this question:

The shaft in Figure P$12-3$ is part of a special machine designed to reclaim scrap aluminum cans. The gear at B delivers $5$ hp to a chopper that cuts the cans into small pieces. The V$-$belt sheave at D delivers $3$ hp to a blower that draws air through the chopper. V$-$belt sheave E delivers $3$ hp to a conveyor that raises the shredded aluminum to an elevated hopper. The shaft rotates at $480$ rpm $.$ All power comes into the shaft through the chain sprocket at C$.$ Use SAE $1137$ OQT $1300$ steel for the shaft. The elements at B$,$C$,$D$,$ and E are held in position with retaining rings and keys in profile keyseats.
