  1. Team Mean Machine

  2. Our Influences R-dog

  3. The “MeanMachine”

  4. Materials We used…. • Pvc pipe • Scrap wood and metal • Marbles • Dominos • Mousetraps • Fishing line • Nails • Plastic cups and pulley

  5. Device Operation/Calculations -Device is set off by a mouse trap, triggering a marble through a series of steps including the use of a pulley, a launcher, dominos, and another mousetrap which all turns on an alarm clock. Equations used to find calculations • Conservation of rotational energy • Conservation of translation energy • Center of mass • Projectile motion • Conservation of linear momentum

  6. Calculations

  7. Design/Problems Blue print for the device originally seemed flawless. Ran into a few problems. • Projectile motion on see-saw was unpredictable and hard to keep consistent eventually leading to minimizing the launch distance and height. • Lack of ideas for an electrical device with an old fashion switch. Led to us making and wiring a makeshift outlet that is turned on by a light switch. Alarm clock is plugged into the outlet. • Mousetrap injuries. • Flimsy cups on a pulley were hard to deal with. • Setting up dominos can also be a pain.
