2. You are constructing a fan using a fan blade and an electric motor. You have two sheaves (pulleys) available in each of these diameters (in inches): 5.0, 8.0, 10.0, 12.0, 16.0, 18.0, and 24.0. One sheave will go on the motor shaft, the other on the shaft of the fan blade. You can space the motor and fan so that you can easily find a belt of the right length. The motor turns at 1720 rpm. You would like the fan to turn at a rate of 400 rpm.

a. Choose a combination of sheaves that can accomplish this task. Note that it may not be possible to find a combination of sheaves that exactly provide the desired fan speed.

b. Which sheave (pulley) goes on the motor (driver) and which on the fan (driven)?

c. Assuming no belt slip, what is the actual speed of the fan (in rpm)?

d. What is the belt speed (in feet/min)?
