Problema Solution
A chain drive runs from a 6-inch sprocket with 18 teeth to a 24-inch sprocket with 72 teeth. How many turns with the small sprocket complete to turn the big sprocket?
Answer provided by our tutors
The ratio of the 24-inch sprocket to the 6-inch sprocket is the same ratio as the 18 teeth to the 72 teeth. We could let 'x' represent the number of rotations:
(6x)/18=24/72
x=1
So one rotation of the 6-inch sprocket is one rotation of the 24-inch sprocket.
