Question

The input gear has 22 teeth on it and the output gear has 45 teeth on it. What’s the reduction ratio? A. 3.3:1 B. 4:1 C. 2:1 D. 3:1

Answer 1

I think the answer to the input gear has 22 teeth on it and the output gear has 45 teeth on it is thst its reduction ratio is 3.3:1.

Answer 2

Number of teeth on input gear= 22 teeth

Number of teeth on output gear= 45 teeth

Reduction=Number of teeth on output gear - Number of teeth on input gear

= 45 - 22

= 23

Reduction Ratio=(Number of teeth on output gear) / (Reduction)

`=(45)/(23)\\\\ (2)/(1)`

→→Option C. 2: 1 is true.
