Question

Determine the speed of rotation of a 20- tooth gear when it is driven by a 40-tooth gear and rotating at 10 rpm​

Answer 1

20 rpm

Step-by-step explanation:

if the lager tooth gear is moving a 10 rpm which will move slower than the smaller 20 tooth gear it will push it faster than the 10 rpm

Answer 2

60 teeth =1/3
the product of the rpm and the gear ratio: 120 rpm *1/3 = 120/3 = 40.
