[SOLVED] Gyroscope problem 1. The problem statement, all variables and given/known data http://www.badongo.com/pic/3634214 3. The attempt at a solution I think this topic is very difficult to grasp, but I've understood that when a torque is applied on the wheel, its angular momentum will chase that torque. One will therefore expect the small wheel to tilt against the woman. I know that the big wheel will start to spin, but why?
