Examine the gear drive system shown below.  All the gears have a DP = 12.  The smallest gear is the primary driver gear and has 15 Teeth, RPM = 3600, and Torque = 2.2 N-m.  That small gear meshes with a 72-tooth gear which is connected to another gear that has 20 teeth.  That 20-tooth gear connects to the final driven gear that has 64 teeth.

    1. What is the final output RPM of the 64-tooth gear?
    2. What is the final output Torque supplied by the 64 tooth gear?
