It kinda opens up arms come at out but not at the same time and er your computer kinda links it with the er the er internet and jam and stuff like you know peanut butter softens the er er disc and your tv reception is oh you know so much better for the whole process and if you are swimming at the time the exact time as this grabs hold of the lamb cutlet er well you can forget the snorkel it makes it irrelevant because well put it er this way if you want to you know work in the er delivery service eer it will depends not only on your um your grasp of er or no maybe it's because I'm a Londoner or or or or not as it as it happens so there you er have it in a nutshell errr yes it's customary to take a bow if you play someone else's fiddle but don't just don't okay it er not worth it not at that price anyway, if er if you can get a few bucks off maybe but only maybe look it's your money and all that so don't get into debt because of it all that's all I'm saying. 8-)

#1 , #2 #3, but not sure about #3 :D>:)

A clutch in a normal car is the reverse of a disc brake and caliper. The engine is turning and the clutch clamps down onto the spinning flywheel of the engine and transfers that to the drivetrain (transmission/driveshaft/axles/wheels) into forward motion.

Just like on a brake system, the clamping has to be gradual. With 10,000 horsepower that clamping has to be even moreso controlled so as not to break the drivetrain or break traction between the tires and the track. These special clutches with various discs and springs make that gradual clamping occur. There's lot's more details on how that happens, but different spring rates make that faster or slower and each time they put a clutch together then can customize how that happens. Like he said, full clamping finally happens about mid-track. Between start and midtrack, there's friction in the clutch unit until full-lockup, just like your brakes until final stop.

For these cars the clutches are rebuilt on every run and lots of things go into deciding how you're going to make that clamping occur such as track conditions, traction, heat, humidity, engine tune etc, etc. A lot is science, but a lot is the gut feel of the clutch builder and often the drivers give credit to clutch builder for their wins because he's basically like a voodoo doctor, guessing to some degree what he needs to do to transfer all that power while maintaining traction and keeping the parts all together for the win! Cool stuff.

Hope that helps.

#4 Yeah maybe but you didn't explain where the jam comes in? It's like you know just like part of an explanation. I mean like I could er I could er tell you just a bit about it you know but would it help in the short term for years ah i doubt it in fact I know it would. The trouble the trouble is as er you know and it doesn't need dwelling on quite as much as much people say they do and if it's in Croatia well so well so so so be it, that's sum that's some small turtle you er you er you have it anyway i think you know and maybe just maybe they could erm get divided you know divided by adding them all together taking away more that you know don't you. Nuff said ok 8-)
