Code Number: 1Q50.90
Demo Title: Maxwell's Tops
Condition: Good
Principle: Precession
Area of Study: Mechanics
Equipment:
Maxwell's Tops.
Procedure:
This is a demonstration of stability about a pivot point. One of the tops has a pivot point above the center of mass and is stable on the pivot whether it is spinning or not. The other has the pivot point below the center of mass and is therefore only stable when spinning.
