String through tube with 2 unequal masses

 

String through tube with three unequal masses,

 

Code Number:1D50.20

Demo Title: Whirligig/Twirling Weights

Condition: Good

Principle: Conservation of Angular Momentum

Area of Study: Mechanics

Equipment: 

String through tube with 2 unequal masses, additional masses.

Procedure: 

The two masses on a string when once started whirling is most safely stopped by pulling back down on the large weight.
