DIY Physics Demo: Duct Tape & Dirt Crew Project

Join Nathan, Luke, Drew, and Mike in their project using plywood, mousetraps, and duct tape to demonstrate physics principles by activating a light. Learn about Conservation of Energy, Rotational Momentum, and Center of Mass. Challenges included attaching tubing without hindering movement and finding a cost-effective device. Discover how this crew overcame construction issues to succeed in their mission!

Presentation Transcript

  1. EF 151 Team Project Duct Tape & Dirt

  2. The Crew Nathan “Mac” Quinn Luke “McGyfer” Whitaker Drew “Sleepy” Randolph Mike “the drunk” Poe

  3. Device Design & Materials Materials: Plywood Scrap wood Nails & Screws Mousetrap Pulley Plastic Tubing Trash Duct Tape Twine Purpose: To activate a small push light while demonstrating physics principles.

  4. Summary of Equations and Concepts Conservation of Energy ½ Ι ωi2 + mg hi + ½ m vi2 = ½ Ι ωf2 + mghf+ ½ mvf2 Rotational Momentum L1=L2 (R × Pi) + (I × ωi) = (R × Pf) + (I × ωf) Center Of Mass R =∑ miri ⁄ ∑ mi

  5. Construction Issues • Attaching tubing to board without impeding marble movement. • Controlling the mouse trap after it was tripped. • Finding a cheap electronic device to activate.

  6. Conclusions
