The Design Marble rolls down PVC Strikes loaded mouse trap Mouse trap pulls string, causing spool with protrusion to turn Protrusion strikes hook, which is attached to counter weight Counter weight slides down string, causing mass to lift

Summary of Stored Energy Energy of ball rolling down PVC: mgh=.003kg X .762m X 9.81=.0224 J Energy stored in mouse trap: 1/2kx2=.5 X 45.1N/m X .179m X .179m=.723 J Energy stored in 5 lb. weight: mgh=2.27kg X 9.81 X .75m=16.7J

Construction Issues Duct Tape is not always the answer Mouse traps are fun, but painful Krazy glue works wonders Support was an issue, but easily solved Marbles are easily lost

Conclusions This project was an interesting application of simple engineering principles It can be hard to work around each other’s schedules, but it can be done It was better than most of the homework
