An important part of an Internal Combustion Engine. It serves the biggest role of an engine, converting Linear motion to Rotary motion. It takes the piston's up-and-down motion, pushing the connecting rod therefore turning the crankshaft. It contains counter-weights to balance the crankshaft so to reduce noise and vibration. It is also connected to the camshaft for timing purposes via a timing belt.

The crankshaft must turn without friction, therefore it has bearings on the case and bearings around the connecting rod. Oil must be supplied, in fact the crankshaft sits in the oil pan. There must be little play, but lateral play occurs, see Crankwalk.

On Manual Transmissions, the wheel with teeth at the end of the crankshaft is called the Flywheel. On Automatic Transmissions, it is called a Flex Plate.
My crankshaft is experiencing crankwalk!

The answer that one gives when asked a question that one either does not know or simply does not want to give an answer to. This response hails from the 'Churchill' car insurance advert in which their mascot dog (Named Churchill) is being asked questions. He gives the answer "CRANKSHAFT" before the lady asking the question has finished speaking.
Example 1:
A: "Do any of you know where my keys are?"

Example 2:
A: "What should I do in the event of a fire?"
