A Ring & Pinion set, with 41 and 15 teeth respectively, has what gear ratio?

Explanation:
The gear ratio for a ring-and-pinion is found by dividing the number of teeth on the ring gear by the number of teeth on the pinion. Here, 41 teeth on the ring and 15 teeth on the pinion give 41 ÷ 15 = 2.733…, which rounds to 2.73:1. This means the driveshaft (pinion) must rotate about 2.73 times for the wheels (ring) to complete one revolution, delivering more torque at the wheels but lower speed.
