Using figures $($a$)$ through $($e$),$ for each speed configuration:

a$.$ Identify which gears are in mesh and which shafts are rotating.

b$.$ Sketch a kinematic model of the configuration $($it does not need to be to scale, but the gears should be in the right locations, and the pitch circle diameters should be accurate$)$

c$.$ From the info in a$,$ determine what the synchronizer is doing

d$.$ Draw the flow of power on top of each kinematic model. $($b$)$

$($c$)$
