The “Mean Machine”
MaterialsWe used….• Pvc pipe• Scrap wood and metal• Marbles• Dominos• Mousetraps• Fishing line• Nails• Plastic cups and pulley
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
Calculations
Design/ProblemsBlue print for the device originally seemed
flawless. Ran into a few problems.1. Projectile motion on see-saw was unpredictable
and hard to keep consistent eventually leading to minimizing the launch distance and height.
2. 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.
3. Mousetrap injuries.4. Flimsy cups on a pulley were hard to deal with.5. Setting up dominos can also be a pain.
