2. Device Design Materials: PVC Pipe Scrap Wood Hotwheels Car
Hotwheels Car Track
Marble
Funnel
Plastic tubing
Lock
Pulley System
UT banner

3. Design Overview
The device begins by placing a marble into the plastic tubing.
The marble shoots out of the tubing into a funnel
The marble exits the funnel and rolls down the pvc pipe configuration
The marble collides with a hotwheels car
The car travels down the track and strikes a platform that is balancing a lock
The lock is attached to a string that is wrapped around the pulley
When the lock falls, the banner is raised

4. Energy Calculations Projectile Motion:
Marble shooting out of the plastic tubing.
Conservation of Translational and Rotational Energy:
Marble rolling down ramp
substituting
Conservation of Linear Momentum:
Marble colliding with the toy car

5. Energy Calculations Cont.
Center of Mass:
Balancing the lock on the platform

6. Conclusions Construction issues:
Drilling the correct size holes in the PVC pipe
Determining the correct height and angle of the track
Troubleshooting the ramp apparatus to work every time
Starting at the end and working toward the beginning to construct the device
More difficult than originally intended.
Good to see how the equations work in real life
