Transmission with teeth-uncompleted gears 2




A funny mechanical problem:

There is a drive of two gears of 20 teeth each.

What is the motion of the driven gear if 1 tooth of the driving gear is broken?

Wrong answer: 1 revolution of the driving gear corresponds 19/20 revolution of the driven gear.

Correct answer:

The driven gear rotates as if the tooth was not broken, because if the driving gear has only 1 tooth, it makes the driven gear move 2 teeth.
