  1. The Green Machine Wade Floyd Hannah Kesler Joshua Atkins Lucas Hofmeister Section B1 TA:Betsy

  2. The Team • Wade-Biomedical engineering major from right down the road • Hannah-this is Hannah’s last day of engineering…she says, “it was fun while it lasted!” • Josh-Nuclear engineering major from JCTC • Lucas-Biomedical engineering major from Nashville Section B1 TA:Betsy

  3. Overview • Make Orange Green! • 99% recycled materials • Three main stages • Gravitational potential to Kinetic • Gravitational potential to Kinetic • Spring potential to work Section B1 TA:Betsy

  4. Purpose • Environmentally friendly method for pulling a party popper • Bonuses: • Gets people excited about environmentalism! • Gets the party started…. Section B1 TA:Betsy

  5. Demonstration • Warning! This process results in a loud noise…you might want to cover your ears Section B1 TA:Betsy

  6. Step 1 • Gravitational potential to kinetic energy • mgh = 0.5mv2 • Bolt sits at the top of pipe=>potential energy • Slides down pipe=>converts to kinetic energy • Does work on the head of the mallet Section B1 TA:Betsy

  7. Step 2 • Gravitational potential energy to kinetic energy • mgh = 0.5mv2 • Mallet at rest at the top of its rotation=>potential energy • Mallet swings down=>converts to kinetic energy • Razor blade cuts string Section B1 TA:Betsy

  8. Step 3 • Spring potential energy to Work • 0.5kx2=work done • Rubber bands are wrapped around dowel axle=>Spring potential • String cutting releases axle=>rubber band recoils and does work on the popper string • POP! Section B1 TA:Betsy

  9. Conclusions • People clearly throw away useful items • Step by step analysis of stages provides a simple physical explanation • Recycled materials were effectively used to demonstrate different energy conversions Section B1 TA:Betsy
