Precession of Spinning Wheel
陀螺的进动
 |
A spinning wheel which is held up by one end of its axle will precess in the sense shown if it has that direction of spin. If the spin is reversed, it will precess in the opposite direction. The sense of precession is determined by the direction of the torque due to the weight of the spinning wheel. That torque is perpendicular to the angular momentum of the wheel. 一个由轴一端支撑的旋转轮，如果其旋转方向如图所示，则会表现出预cession（进动）。如果旋转方向反转，它将表现出相反方向的进动。进动的方向由轮的重量所造成的力矩方向决定。该力矩垂直于轮的角动量。 |
