Demonstrations are cataloged according to PIRA Bibliography
PLEASE REQUEST DEMOS WELL IN ADVANCE
Due to Physics Building renovations, the lead time to set up demo requests has increased due to the need to transport equipment across campus. Please be kind and let me know well ahead of time what you need.

Air GyroPurpose:To show precession of gyro around spin axis in relation to applied torque and also to show nutation.Procedure:Turn air on (only a small amount need to be used). Place gyro in position and start spinning by hand. The air gyro is extremely friction free and will rotate an extended period of time at very slow speeds. This facilitates close examination. A loop may be tied on one end of the string and this placed over the end of the gyro shaft (into the groove). When a torque is applied to the shaft, the gyro precesses in the appropriate direction. A swift, light, blow to the shaft will cause nutation. Weights and pulleys may also be used for a constant torque which causes a proportional rate of precession.Equipment:
