A is a fundamental mechanical component—an arm attached at a right angle to a rotating shaft—used to convert circular motion into reciprocating (back-and-forth) motion, or vice versa. It is a cornerstone of mechanical engineering used to manually or mechanically turn axles, powered by either human effort or engines.
The crankset is powered by feet on pedals, transferring force to the chainring.
Evidence of hand-cranked rotary handmills appeared in Spain (5th Century BC) and later Greece. A 2nd-century AD Roman iron crankshaft was found in Switzerland.
Early automobiles required a starting crank (a "starting handle") to initiate the engine, a technique still used in some specialized or historic vehicles.
A specialized rotating axle in engines that includes multiple cranks for driving rods.
A crank consists of a crank arm (or web), a shaft (or axle), and a crank pin.
Manually operated car windows use a crank to roll the glass up or down. 3. History of the Crank
