  1. Engineering 100:Bridge Project Group 6 (Team Bacardi) Jon Honari, Kevin Lam, Otis Chantharangsy, Ivee Ilao

  2. Design Ideas Prototype Bridge Process Testing/Results Prototype Analysis Flaws Improvements Final Bridge Design Testing/results Final Results Graph Analysis Failures Conclusion Presentation Outline

  3. Design • Arch Design • Proved to be strongest structure based on our research • Base • Flat and straight • Supports • Angle supports • Evenly distributed force

  4. Prototype Design

  5. Prototype Process • Arch • Supports • Road • Connections • Structural Reinforcements

  6. Prototype Process

  7. Prototype Testing/Results

  8. Prototype Analysis • Flaws • Uneven weight distribution • Not supported where bridge met jig • Ultimate reason for failure • Weak road • Sloppy design • Unnecessary weight

  9. Prototype Flaws Red: Excess Weight Green: Lack of Support

  10. Final Design • Excess weight was removed • Top section was more reinforced • Used wood glue instead of hot glue for the majority • Made sure weight was distributed evenly • Reinforced the legs where the bridge met the jig • Added more supports

  11. Final Bridge Prototype Prototype vs. Final Design

  12. Final Design (Completed)

  13. Final Testing/Results

  14. Final Design Failure Important joints were overlooked and were not supported correctly

  15. Final Analysis • Overall, very good improvement • Bridge weighed 0.59 lbs • Bridge held 531.89 lbs • Performance = Successful • With more supports in the correct places we believe the bridge could hold much more weight

  16. We conclude… • Spending more time on the construction yielded better results • About 170% improvement • High efficiency ratio • Endures a high amount of pressure • Lasts under consistent amount of low pressure • First Bridge: .56 pounds, held 296.00 lb • Final Bridge: .59 pounds, held 531.89 lb
