D.E.A.N. Device Enabling Ample Nonsense E2-6 Troy Eckleberry Fareed Yasin Adele Poole Anna Green
Steps 1. A pin is pulled releasing a projectile. 2. The projectile hits a target on one end of an axle. 3. The opposite end of the axle triggers another, similar axle. 4. Smaller axle knocks a ball into a tube. 5. The ball collides with a ball of identical mass at the bottom of the tube. 6. Both balls roll on an open PVC pipe and then a.fall into a catcher attached to the bottom of a banner displaying UT spirit. b.collide with Step 1 of the next groups device.
Concepts Trajectory: pin releases key chain Conservation of angular momentum: axles rotate Conservation of energy: golf ball rolls down tube Collision: golf ball hits second golf ball Torque: banner opens
Calculations Overview Trajectory: Torque: Collision: Conservation of Energy: Conservation of Angular Momentum:
Issues Triggering projectile Cost dictated lighter materials Accuracy and precision of projectile Structural stability Triggering successive group (constructing alternate route)
Conclusions Creativity was necessary to navigate a low budget and various technical difficulties Team work and good attitudes were crucial to success Applying the concepts is not always easy but very do-able and fun!
