Anyone know how to calculate the rmp when your given for example 'if gear a is rotated at 42 revs per min (15 teeth on gear a  7 teeth on gear b 5 teeth on gear c) what is the rotational speed of gear wheel c?'

Hi Padraigoc! Since Gear C is three times smaller than Gear A, Gear C will have an rpm three times larger than Gear A. This means Gear C will rotate at 126rpm (42rpm × 3).

Thanks a lot :)
