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

Calculations Overview


Issues

  • Triggering projectile

  • Cost dictated lighter materials

  • Accuracy and precision of projectile

  • Structural stability

  • Triggering successive group (constructing alternate route)
