It’s cereal time in Tennessee

1. It’s cereal time in Tennessee Project by: Chris Bates Ben Dabbs Rob Noe Josh Schwartz Michael Mccormick Michael Warden

2. Overview While using carts and ferris wheels in a set sequence as a Rube Goldberg machine, we will make a bowl of cereal.

3. How it works. We used ferris wheels and carts to move the different components around. Only one act is required from outside of the system and that’s the initial moving of the cart. All other energies are either potential or kinetic.

4. Building Process Building took about 6 hours total. Never really designed anything, just put it together. Had to discard some ideas after testing because of timing issues.

5. Important Info • Masscart1 = .0107 slugs • Masscart2 = .0107 slugs • Massball = .00446 slugs • Massbowl = .00582 slugs • Masscounterweight = .058 slugs • Radius1 = .563 ft • Radius2 = .75 ft • Height1 = .873 ft • Height2 = .167 ft

6. Some discovery • Balance was important. (bowl) • Bigger isn't necessarily better (the second Ferris wheel) • Timing is everything. (triggers)

7. 5 Stages We used 5 stages in our Rube Goldberg machine. • Cart and ball rolling down the track • Car starts first ferris wheel • First ferris wheel delivers cereal and the ball releases the bowl from rest • Second cart moves down the track and initiates second ferris wheel • Second ferris wheel delivers milk

8. Energy Conversions (By Stage) • Potential Energy → Kinetic Energy • Kinetic Energy → Kinetic Energy • Potential Energy → Kinetic Energy • Potential Energy → Kinetic Energy • Potential Energy → Kinetic Energy

9. Bill of materials • K’NEX: Previously owned • PVC Pipe: Previously owned • Bowl: Previously owned • Cereal and Milk: $3.00 • String: Previously owned • Rubber Bands: Previously owned • Golf Ball: Previously owned • Total Cost: $3.00

11. Conclusion • An overall success • Combined 6 people’s ideas into one project • Used our knowledge from the class and ingenuity from experimentation
