There is a gear train system and:

Driving gear has 32 teeth, Idle gear has 12 teeth, Driven gear has 20 teeth.

What is the gear ratio of this mechanism?

• 5:8

• B) 8:5

• C) 12:20

• D) 20:12

Answer explanation

The gear ratio is calculated by dividing the number of teeth on the driving gear by the number of teeth on the driven gear. Therefore, the gear ratio in this case is 32:20, which simplifies to 8:5.
