Plato By: Nick Moran, Whitney White, and Kelsey Dietz
Overview Structure made fundamentally of Styrofoam and wood. Ping-pong balls filled with Play-Doh. Bobbins and thread used as pulleys. Newtonian Cradle: wood structure, Play-Doh filled ping- pong balls, thread, bobbins, scrap metal, and dowl rods. Scissors to initiate the device. Energy Used: Linear momentum Projectile motion Torque Center of mass Angular momentum
How it works… Scissors set off the Cradle. Newton’s Cradle: Linear Momentum
How it works… A ball rolls down the Styrofoam track. Ball hitting the target: Collision Target rotating T-shaped rods: Torque Ball rotates T-shaped rods.
How it works… Block weight drops off seesaw and raises the flag. See-saw: Center of Mass Raising the flag: Angular Momentum
Difficulties • Finding a time and place where everyone could meet • Not being able to text Whitney • Nick getting his phone’s Sims card jacked • Kelsey living across campus from Morrill • Sleep deprivation • Having EF homework due when we needed to be working on this project • Transporting the device • Not being able to use fire or a guillotine and settling for scissors • Being poor college students • None of us like talking in front of group • The ADD attention span of nick
Conclusions The project was enjoyable to build. We got to use the skills we learned throughout the course. We learned that the three of us make a good team. Time flies by when you’re having fun. Engineering is fun and a good major choice. It was cool to see the culmination of our efforts and skills come together.
