Just curious. |

Jan 23, 2003 1:47 PM | | A bell crank is a mechanism that changes the direction of motion or force through 90º (or something close to 90º). It is basically a lever with two arms at right angles with the pivot where the two arms connect. It is called a bell crank because in olden days it was used to operate actual bells, like doorbells. |
