Hinge on Roller Skates, rods, string, paperclip chain, mass set.

Code Number: 1J30.30

Demo Title: Break a Wire With a Hinge

Condition: Good

Principle: Vector Addition of Forces

Area of Study: Mechanics

Equipment:

Hinge on Roller Skates, rope, string, or paperclip chain, mass set.

Procedure:

Set the apparatus up so that it has a small angle. You should be able to hang several kilograms of mass from the apparatus in this position. Then adjust the chain so that the apparatus has a larger angle and note that the chain will now break when the same amount of mass is hung from the apparatus.
