Consider only two of the gears in the gear set, the 12–36 and 12–42 tooth gears. For any given input speed, how many different output speeds are possible? Illustrate by categorizing the number of configurations that (1) increase or decrease the final shaft speed, (2) increase or decrease the final torque, and (3) leave the final speed and torque unchanged compared to the drive motor.

Concern a gear set consisting of up to the three gears as shown here. In each case the larger (36 or 42 tooth) and smaller (12 tooth) portions of each gear are fastened together so that they rotate at the same rate.
