A car is powered by the energy stored in a single flywheel with an angular momentum L. Discuss the problems that would arise for various orientations of L and various maneuvers of the car. For example, what would happen if L points vertically upward and the car travels over a hilltop or through a valley? What would happen if L points forward or to one side and the car attempts to turn to the left or right? In each case that you examine, consider the direction of the torque exerted on the car by the road.
