3. Rube Goldberg Project
Objective: Build a device that will display a banner in the most inefficient, redundant way possible
Constraints:
Must fit in a .5m x .5m x .8m box before operation (during operation size is unconstrained)
Be assembled in under 1 minute
Have a minimum of 5 steps, 4 of which must include concepts we have learned from class
Total construction cost must be under 20$
The device must run without any assistance from the engineers once triggered
Can not be in action for longer than 2 minutes
Must be triggered by another device and also trigger a device
Why the Mighty Ducks?

4. Materials
Wood
Lever
Billiard Ball
Spring
Cup
Funnel
PVC
String

5. Start 1)Wooden plank hits ball 2)Ball rolls down pvc pipe
3)Ball hits spring and bounces into the funnel
5)The string attached to the hinge is pulled up causing the sheet, covering the banner, to tear off
4)Hinge weighed down by the ball goes down

6. Finish

7. Design and Construction
Coming up with a simple, unique yet redundant design with the skill available was very challenging and time-consuming.
Construction:
Our design changed many times throughout construction
Power tools, hammers and screw drivers were all things that most of us were not familiar with – we learned a lot during construction
Set backs:
Our troubles first began with our materials list; some objects were too heavy, others too expensive
On the first trial run the ball kept rolling off of the side of the PVC
Fine tuning the spring to project the ball into the funnel with precision every shot

8. Energy Step 1: Perfectly elastic Collision m1v1 = m1v’1 + m2v’2
Step 2: Conservation of Translational Energy
.5mv^2+mgh=.5mv’^2+.5Iw^2
Step 3: Conservation of Energy
.5kx^2=.5mv^2
Step 4: Rotational Energy
.5mv^2+.5Iw^2=.5mv’^2
Step 5: Perfectly inelastic collision
.5mv1^2+mgh=.5Iw^2

9. Conclusion
An open ended problem was solved and our final product is consistently inefficient and redundant
Our group learned how to work well together and new friendships were formed
A lot of fun was had, engineering concepts and ways of communication were learned
