Crankshaft (noun)

A shaft in an internal combustion engine that converts the linear motion of the pistons into rotary motion, which is then transferred to the wheels through the transmission.

Origin:

The word 'crankshaft' is derived from the word 'crank' meaning 'a bent part of an axle used to transmit rotary motion' and 'shaft', meaning 'a long rod or pole'. it refers to a shaft in an internal combustion engine that converts the linear motion of the pistons into rotary motion.

Examples:

1. The crankshaft is a critical component of the engine, responsible for converting the energy from the pistons into motion.
2. The crankshaft was damaged in the accident, requiring replacement.
3. The crankshaft's balance and strength must be precise in order to ensure smooth operation of the engine.
4. The crankshaft is made of high-strength steel and undergoes strict quality control during production.
5. The crankshaft is a key factor in determining the engine's power output and overall performance.
