I don't know much about the inner workings of a car. For driving one, I find that having an rough idea about what the gearbox, engine and clutch do and where they are is often enough.
However for the life of me I can't figure out one thing. You know when you want to get the car moving again from a complete stop, you raise the clutch to the biting point, release the brake and start to accelerate? As the clutch gets to the biting point yet before the car is able to move, for the wheels are kept still by the brake, the front of the car lifts up. What is lifting the front of the car up? Surely if the wheels are not actually rotating, inertia isn't the cause. What's at work here?
If you object to the question enough to downvote it, why not explain yourself and suggest ways to improve it?
