Steps 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

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 Concepts

Calculations Overview Trajectory: Torque: Collision: Conservation of Energy: Conservation of Angular Momentum: Calculations Overview

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

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
