Code Number: 1Q50.72
Demo Title: Gyroscopes - Ship Stabilizer
Condition: Fair
Principle: Conservation of Angular Momentum about Vertical Axis
Area of Study: Mechanics
Equipment:
Gyroscope, Ship Stabilizer apparatus, 0 - 20 VDC power supply.
Procedure:
Start the Gyro and allow it to come up to speed. This may take up to a minute. Then try to rock the "ship" and watch as the Gyro moves 90 degrees to this motion while trying to counteract the rocking.
