# Ratchet Effect

What if applet does not run? |

The applet above offers a simulation of the ratchet effect. Two stair like plates move alongside each other ultimately downwards. However, while one of them slides down uniformly, the other one staggers up and down, with the cumulative motion still being downwards. The two create a curious ratchet effect: they cooperate to move an object upwards.
