Demo 07-11 Gyroscope with Adjustable Weights

A small gyroscope is balanced by a weight whose radius can be adjusted, as shown in Figure 1. When the spinning gyroscope is balanced no precession occurs. If the weight is repositioned along the arm, unbalancing the system, the gyroscope will precess. The direction of precession depends on whether the weight is closer to or farther away from the pivot than the balance point
