  1. The Incredible Bridge alice yi - collin larson - jason truong - michael lenning Created by Team Incredible

  2. Assignment Materials Design Ideas Prototype Testing/Results Prototype Analysis Flaws Improvements Final Design Final Results Conclusion Contents…

  3. Assignment… • Build bridge with materials provided that fit the guidelines

  4. Materials Used… • 6” Senior Tongue Depressors • Carpenter’s Wood Glue • Hot Glue • File • Binder Clips • Ruler/Saw/etc.

  5. Design Ideas… • Main goals: • disperse weight to the sides • maximize amount of compression the bridge can withstand • efficiency (compression vs. mass)

  6. Prototype… • Design

  7. Prototype… • Results: • Weaknesses: A break in the base: A break in the arc:

  8. Improvements… • Shortened the height • Added more layers • Focused on strengthening the weak areas from prototype • Increased width of bridge • Added additional inner supports • Added decorations ^.^

  9. Final Bridge… • Design

  10. Final Bridge… • Results: • Attempt 1 (Horizontal):

  11. >>Attempt 2(Vertical)

  12. Conclusion… • Better efficiency (weight - compression) • Same weight, stronger bridge • By reducing height, adding strength through layers, we achieved greatness! • First Bridge: 0.61 pounds, held: 371 lbf • Final Bridge: 0.62 pounds, held: 500.1 lbf
