The clutch pedal is that third one you’ll find in manual transmission cars, the one on the far left a driver must press for every gear change. If you can drive stick, then you already knew that. But you might not have spent much time thinking about the nitty-gritty mechanics of the clutch.
The short version is that changing gears in a manual transmission car requires disengaging the power flow from your engine to the transmission. The clutch is a disc that accomplishes this disconnection.
The assembly around it includes what’s called a diaphragm spring, which allows the clutch to engage or disengage the engine depending on whether you’ve pressed the clutch.LearnEngineering’s visuals do a nice job of walking you through the friction and fine details.
