Clutches are mechanisms that can connect or disconnect two rotating shafts, allowing them to either spin together or at different speeds. They are commonly used in devices that have a motor-driven shaft and another shaft that drives another component. A typical clutch consists of a flywheel, clutch disk, pressure plate, and throw-out bearing. When the clutch is engaged, the disk is squeezed between the flywheel and pressure plate, transmitting power from the engine to the transmission. When the pedal is depressed, it disengages the pressure plate from the disk, interrupting the power flow. Multiple plate clutches have several interleaved driving and driven plates.
