A crankshaft is a rotating metal shaft inside an engine that converts the up-and-down motion of pistons into rotational motion, which ultimately powers the wheels of a vehicle. It's essential to how engines work because without it, the linear movement of pistons couldn't be transformed into the spinning action needed to drive machinery.
