What converts the reciprocating motion of the piston into rotating motion?

• A. Piston Rod
• B. Flywheel
• C. Crankshaft
• D. Gearbox

Answer: (C)

The crankshaft is the component responsible for converting the reciprocating motion of the piston into rotating motion. In an engine, as the piston moves up and down within the cylinder due to combustion, this linear motion is transferred to the crankshaft through a connecting rod. The crankshaft then rotates, facilitating the conversion of this motion into an effective output that can drive other components, such as the vehicle's wheels in an automotive application.

Understanding the role of the crankshaft is crucial in the context of internal combustion engines, as it plays a significant role in the engine's overall operation and efficiency. The design of the crankshaft allows for alternating piston movement to maintain a smooth and continuous output of rotational energy, which is essential for the functioning of various mechanical systems.
