The clutch is a mechanical device that connects two or more rotating shafts in a car. It is a vital part of the cars working machinery as it transfers the rotational power from the engine to the wheels in any manual vehicle. In a manual transmission car, the clutch controls the connection between the shaft coming from the engine and the shafts that turn the wheels. The clutch both engages and disengages the power transmission from the driving shaft to the driven shaft. It allows the car to change speed and come to a complete stop without turning off the engine. The clutch has two main parts: the clutch plate and the flywheel. When the driver presses the clutch pedal, it disengages the clutch plate from the flywheel, which temporarily breaks the connection between the wheels and the engine. This allows the driver to shift gears and control the speed of the car.
