1J30.30 - Break a Wire With a Hinge

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.
