crankshaft

Piston motion translator

A crankshaft is a rotating shaft in an engine that converts the up-and-down motion of pistons into rotational motion.

This conversion is what ultimately turns wheels or propellers.

The crankshaft is fundamental to internal combustion engines—without it, the explosive force in cylinders couldn't become useful work.
