Device Design
Our device’s purpose is to
stamp a piece of paper. It
accomplishes this in a 4
step process.
1. Car is released down a ramp.
2. The car’s trajectory sets off a
trail of dominoes.
3. The last domino sets off the
trigger on a mousetrap.
4. The stamp is attached to an
arm on the mousetrap, which
stamps the paper.
Energy Conversions
1. There is Potential Energy in the car, due to gravity.
2. The Potential Energy turns into Kinetic Energy as it
moves down the ramp.
3. The Kinetic energy becomes Gravitational Potential
Energy and lost-energy in the Collision.
4. The Kinetic Energy, through Conservation of
Momentum, knocks over the series of dominoes and
lands on the mousetrap trigger.
5. The stored Potential Energy in the spring is released
and converted to Kinetic Energy which moves the arm
and stamps the paper.
Construction Issues
•
•
•
We had problems with attaching the dominoes to the
metal hinges.
We also had design issues concerning the spatial
requirements.
Making sure the car consistently hit the target area.
Conclusion
•
Not a efficient method of stamping paper.
•
We had a great learning experience.
•
Amazing how much can be contained in such a small
space.
