D.E.A.N. Device Enabling Ample Nonsense

This project details the design and function of a device that triggers a series of mechanical reactions using conservation principles from physics. A pin release initiates a chain reaction where a projectile hits a target, setting off secondary axles that facilitate further ball collisions. These interactions lead to a final result where balls roll down PVC pipes and activate a banner demonstrating school spirit. We navigated technical and budget challenges through teamwork and creativity, highlighting the importance of precision, structural stability, and the engaging nature of applying physics concepts.

  2. A pin is pulled releasing a projectile. • The projectile hits a target on one end of an axle. • The opposite end of the axle triggers another, similar axle. • Smaller axle knocks a ball into a tube. • The ball collides with a ball of identical mass at the bottom of the tube. • Both balls roll on an open PVC pipe and then • fall into a catcher attached to the bottom of a banner displaying UT spirit. • collide with Step 1 of the next group’s device. Steps

  3. 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 Concepts

  4. Trajectory: • Torque: • Collision: • Conservation of Energy: • Conservation of Angular Momentum: Calculations Overview

  5. Triggering projectile • Cost dictated lighter materials • Accuracy and precision of projectile • Structural stability • Triggering successive group (constructing alternate route) Issues

  6. 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! Conclusions
