  2. The Team

  3. Overview • Design and build a Rube-Goldberg device that will perform a simple task of your choosing. • Our goal: To make a mouse trap alarm, when trap is sprung.

  4. Overview Cont. Steps: • Mouse trap, when sprung, initiates arm. • Arm swings around 270° and hits golf ball. • Golf ball rolls down track. • Half way down track golf ball hits chime.

  5. Energy Conversions • The mouse trap applies a force of 9N up when sprung. (measured with scale) • The arm then has an vi. • After finding the vi it is used in the COE to find its vf just before hitting the golf ball.

  6. Energy Conversions • After the ball is hit it then has a vi which can be found using the COM. • The velocity of the ball right before it hits the chime can be found using the COE. • The velocity of the ball just before it hits the end can also be found using the COE. (Eloss from hitting the chime is negligible)

  7. Initial Measurements • Mouse Trap: Force= 9N • Arm: 12” long Mass= .037 Kg • Golf Ball: Mass= .0459 Kg Initial height= 12” above datum • Wind-chime: 12” down track • Track: 23” long

  8. Conclusion It took a little bit of adjustment, but we got it to work just the way we wanted. It was cool to be able to design something that should work on paper, and actually have it work when it was built.
