Question

What is the gear ratio if the number of teeth on the driven gear and pinion is 50 and 180 respectively?

A. 5/18
B.9/2
C.2/9
D. 18/5

Answer 1

The gear ratio is option a)5/18.

Step-by-step explanation:

The gear ratio is determined by dividing the number of teeth on the driven gear by the number of teeth on the pinion. In this case, the number of teeth on the driven gear is 50 and the number of teeth on the pinion is 180. Therefore, the gear ratio is 50/180.

To simplify this ratio, we can divide both the numerator and the denominator by 10, resulting in a gear ratio of 5/18.

So, the correct answer is A. 5/18.
