In the year 1930s, some trucks used a chain to transmit power from the engine to the wheels. Suppose the drive sprocket had a diameter 6 in., the wheel sprocket had diameter 20in., and the drive sprocket rotated at 300 rev/min.
a) Find the angular velocity of the drive sprocket in radians per second.
b) Find the liner velocity of the wheel sprocket in inches per minute.
c) Find the angular velocity of the wheel in radians per minute.
d) If the wheel has a diameter 38in, find the speed the truck is going to nearest mile per hour.
