(adsbygoogle = window.adsbygoogle || []).push({}); help -- what's a flywheel?

This is a somewhat nasty homework problem from Kleppner and Kolenkow that I don't even know how to begin to set up (never spent much time with cars, I guess.)

"When an automobile rounds a curve at high speed, the loading (weight distribution) on the wheels is markedly changed. For sufficiently high speeds the loading on the inside wheels goes to zero, at which point the car starts to roll over. This tendency can be avoided by mounting a large spinning flywheel on the car.

"a. In what direction should the flywheel be mounted, and what should be the sense of rotation, to help equalize the loading?

"b. Show that for a disk-shaped flywheel of mass m and radius R, the requirement for equal loading is that the angular velocity of the flywheel, omega, is related to the velocity of the car v by

omega = 2v(ML)/(mR^2)"

What is a flywheel and where does it go -- inside the car, somewhere on the outside, or what? I imagine you'd want to create a downward torque near the inside wheels, but I can't see where the flywheel would attach.

On the lucky chance that somebody stops by and knows what to do about this, thank you.
