» Main goals: » disperse weight to the sides» maximize amount of
compression the bridge can withstand
» efficiency (compression vs. mass)

Conclusion…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
