Goals and Constrictions

• Goal
• Build an efficient bridge

• Constrictions
• Limited Materials
• Limited dimensions
• Limited Time

5
Group Goal

• Our group initially decided that we were going to
  focus on efficiency rather than overall weight
  the bridge can support. For these reasons both
  the prototype bridge and the final bridge was
  created using fishing line as substantial
  material.

6
Prototype Testing

• Types of Considered Bridges
• Cable Stay Bridge
• Suspension Bridge

7
Our Choice Cable-Stay Bridge

• Reasons why we picked a cable-stay
• The supported weight will be forced down to the
  sides of the jig
• Less materials because we will utilize the
  fishing line
• Aesthetically pleasing a.k.a. sexy

FAILURE POINT

Results of the Prototype Test

• Weight 0.685 lbs
• Max. Load 70 lbs
• Efficiency 102
• The prototype bridge failed because the fishing
  line was not under tension. Therefore all the
  weight was being supported by the deck, which was
  not designed to support all the weight on its own.

10
Final Design

• Changes made to the final design
• Complete redesign of the bridge
• Final bridge will have a string based structure
• Reasons for the changes
• More efficient than prototype
• Less complicated than prototype
• And still sexy

The Final Bridge
Carlos Santana (named for obvious reasons)
12
Results of the Final Test

• Weight 0.04 lbs
• Max. Load 75 lbs
• Efficiency 1875
• The results of the final test were very pleasing.
  The bridge didnt actually fail, instead as the
  string flexed the metal plate that was resting on
  the string interfered with the jig. As a result
  we had to stop the test. Our improvement worked
  just as we had planned. The bridge was very
  efficient as seen by the efficiency rating.

Irony?... I think not

In Conclusion

Final Thoughts and Suggestions

• Final Thoughts
• We would have used a different size metal
  platform so Carlos Santana could have tested
  until failure
• Suggestions
• Have good group communication
• Budget materials wisely
• Spend plenty of time at the drawing board
  designing the bridge
• When gluing, dont use too much glue and clamp
  the wood while it is drying

Good! Because I want to go check and see if my
hair still looks as good as it does in this

THANK YOU Very Much Are there any questions?
