If you are like me you can drive for years and have a 'feel' or a basic understanding of that is a clutch
but you still don't understand what it really is on a vehicle and how it operates.
I'm done with daily use of things I don't understand so I looked on the net for readings and among others, I found this article and very straight to the point video from Howstuffwork.
It tells and shows the various parts flywheel, crankshaft, input shaft, pressure plate, clutch disc and explains how friction is used to connect elements and get power to your wheels for spinning.
So now you should know what is really happening when you hear a horrible grinding noise:
it's the sound of the friction between the flywheel and the clutch disc which is made of ceramic based materials in today's cars (asbestos in some older cars).
If you still don't get it, have a read of this article about transmission on Howstuffwork
and watch more videos.
If you prefer real images to animations, watch Ericthecarguy's very articulate take on the topic
