Final answer:
The 'pressure plate' is the component of the clutch cover that presses the clutch disc against the flywheel, crucial for transmitting engine power to the transmission.
Step-by-step explanation:
The pressure plate is the surface of the clutch cover that squeezes the clutch disc against the flywheel. When the clutch pedal is released, the pressure plate pushes against the clutch disc, pressing it against the flywheel, which allows for the transmission of power from the engine to the transmission.
The pressure plate, in conjunction with the clutch disc and flywheel, are essential components of a vehicle's clutch assembly, which plays a critical role in managing the connection between the engine and the transmission.
