Prototype Testing/Results

Prototype Analysis Flaws

Uneven weight distribution Not supported where

bridge met jigUltimate reason for failure

Weak road Sloppy design Unnecessary weight

Prototype Flaws

Red: Excess Weight Green: Lack of Support

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

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 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… 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
