Precession of Spinning Wheel

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.
