Question

when gears are equal in size, what is the gear ratio? 1:3 1:1 1:2 2:5

Explanation:

Gear ratio is calculated as the ratio of the number of teeth on the driven gear to the number of teeth on the driving gear. When gears are equal in size, they have the same number of teeth. So the ratio of their teeth numbers is \(1:1\).

Answer:

B. \(1:1\)
