Question 2 of 5

Gear Ratio

The mechanical advantage (amount of change in speed or torque) of connected gears is proportional to the number of teeth each gear has. Called gear ratio, it's the ratio of the number of teeth on the larger gear to the number of teeth on the smaller gear. For example, a gear with 12 teeth connected to a gear with 9 teeth would have a gear ratio of 4:3.

If you have a gear train with three gears, the first with 24 teeth, the second with 10 teeth, and the third with 6 teeth, what is its mechanical advantage?
