Compound Level

Students will learn how to calculate compound gear ratios and determine the effect it has on the speed and torque.

Lesson Notes

Homework Assignment: Compound Gear Ratios Homework

Answer Key

1. GR = 25/9 More torque, less speed

2. GR = 1/15 Less torque, more speed

3. GR = 3/25 Less torque, more speed 

4. GR = 3/5 Less torque, more speed

5. GR = 1/125 Less torque, more speed 

6. GR = 9/5 More torque, less speed 

7. First level = 48:48, Second level = 36:12, Third level = 60:12
