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
