Design w Arch Design w Proved to be strongest structure based on our research w Base w Flat and straight w Supports w Angle supports w Evenly distributed force
Prototype Design
Prototype Process w Arch w Supports w Road w Connections w Structural Reinforcements
Prototype Process
Prototype Testing/Results w�
Prototype Analysis w Flaws w Uneven weight distribution w Not supported where bridge met jig w Ultimate reason for failure w Weak road w Sloppy design w Unnecessary weight
Prototype Flaws Red: Excess Weight Green: Lack of Support
Final Design w Excess weight was removed w Top section was more reinforced w Used wood glue instead of hot glue for the majority w Made sure weight was distributed evenly w Reinforced the legs where the bridge met the jig w Added more supports
Prototype vs. Final Design Final Bridge Prototype
Final Design (Completed)
Final Testing/Results
Final Design Failure Important joints were overlooked and were not supported correctly
Final Analysis w w w 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
We conclude… w Spending more time on the construction yielded better results w About 170% improvement w High efficiency ratio w Endures a high amount of pressure w Lasts under consistent amount of low pressure w First Bridge: . 56 pounds, held 296. 00 lb w� Final Bridge: . 59 pounds, held 531. 89 lb
