Probelm 2. (3 Points) As we derived in Problem 1, the precession of horizontal angular momentum will result in an additional vertical force on the rotating object. We can ultilize this to stablize the car while turning. For this purpose, the flywheel should be mounted parallel to the wheels of the car, turning in the opposite direction of that of car wheels.

Unformatted text preview: The torque relative to point O from f1 and f2 is The torque relative to point O from additional vertical force induced by the precession of the flywheel is , in which is the angular velocity of flywheel, is the angular velocity of precession (the car). So, = = Equal loading requires zero torque relative to point O, thus, T1= = T2 That gives...
