EF 151 Team Project Duct Tape & Dirt
The Crew Nathan “Mac” Quinn Luke “McGyfer” Whitaker Drew “Sleepy” Randolph Mike “the drunk” Poe
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.
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
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.
