  2. Overview of Design Wood platform and towers. Spiral tube using gravity. PVC tube. Newton’s Cradle Stick with a needle. Balloon with weight inside Mouse Trap Bottle Opener that plays “Rocky Top” Costs: Bottle opener: $10 Needles: $4 Everything Else: FREE

  3. Summary of Design PVC Pipe Spinning down Spiral Steel ball rolling down slope Ball starting a Newton’s Cradle Stick with needle on end falling onto balloon Balloon popping, releasing pellets. Pellets springing a mouse trap 1 5 2 3 6 & 7 4 7. Mouse trap connects batteries to speaker, beginning “Rocky Top”

  4. Calculations used • Hollow Cylinder (Angular Momentum) L=Iω • Ball Rolling down pipe ramp (COE) mgh=(1/2)mv² + (1/2)Iω² • Newton’s Cradle (Collision/Linear momentum) m1v1+ m2v2= m1v1’ + m2v2’ • Stick Balancing (Center of Mass) R = m1r1 + m2r2… m1 + m2… • Trap Springing (Torque/Rotational Energy) τ = F•r•sin(θ)

  5. Problems with design • Spiral would not cooperate, had to make many different types. • Stick would not pop balloons with nails, had to go buy actual needles. • Could not find a suitable electronic device for the trap to set off. • Once we got the piece we could not get the metal pieces to connect correctly

  6. Conclusion • We visually learned the applications from our lectures from the past four modules • We learned that time management is a key to a successful group project. • It was a fun, but intellectually tiring project.
