The online racing simulator
Quote from Crashgate3 :Imagine a dragster accelerating hard from a standing start, but on a frictionless surface. The nose will still try to pitch up (to the point of needing the wheelie-bars if the wheels are heavy enough and the force overcomes gravity, but you'd need comically big wheels to acheive this) as the wheels spin up due to the inertia of the big wheels, even though there is no grip.

It's the same effect on a normal car, but greatly reduced due to the smaller wheels, friction with the ground and much less torque.

Someone needs to work out some figures (haha, not me ), to see how much force this effect would have with a 'normal' car.

Assuming the car, floating in mid-air with the wheels stopped, weighs 1000kg, the wheels 100k, and both have the same lever arm, the car would rotate 10 times slower than the wheels once you accelerated them. Take into account the lever arm of the car (~1.5-2m ??? drive axle to CoG) versus the wheel (~0.25m mass radius on a wheel with a 0.7m diameter tire, such as 225/60/17), and that ratio drops to about 1:60 to 1:80. And that's a fairly light car with fairly heavy drive wheels, nearly 2 full orders of magnitude.

I'm talking strictly rotational velocity here with no external resistance.
