Question

Gear A has $$5$$ teeth and is engaged with Gear B, which has $$20$$ teeth and rotates clockwise. For every one rotation of gear B, gear A will rotate how many times and in what direction?

Accepted Answer

The ratio of teeth in gear B to gear A is $$\frac{20}{5} = \frac{4}{1}$$, so for every rotation of gear B, gear A will rotate $$4$$ times in the opposite direction (counterclockwise) to gear B.
