The Competition

•Story: Olympics will be held at Lilliput at the same time they will be held in London, GB. The games will attract many more spectators that the current bridges can handle. Design a bridge at Lilliput that can be temporary and yet hold up to the abuse that the spectators will put it through.

•The Goal:

–Build in the shortest amount of time the lightest, cheapest, environmentally friendly bridge that can hold 20lb out of the K’nex

Competition Rules:

•Teams may only use parts given in the bridge kit

–Max total pieces = 400 (connectors + rods)

•Teams may not use any glue or any other binder

•The bridge must span 35” and have piers at least 19.5” tall

•The bridge construction will be timed

•Bridges will be weighed after construction

Costs:

•Each member will have a cost

•The teams must provide a cost for their bridge

•Red = $250 =(5in*$50/in)

•Yellow Connectors = $45 =[180degrees ($0.25/degree)]

•3D connectors = $135 = [540 degrees * ($.25/degree)]

Environmental finances:

•Each member will have a cost

•The teams must provide a potential environmental impact assessment for their bridge

•Red = 682 kg of CO2 =[5in*1364 kg/ 10 in.]

•Yellow Connectors = 2.5 kg of CO2 =[180 degree .001*180 degrees]

•3D connectors = 30 kg of CO2 =[540 degree .001*540 degrees]

Speed:

•The bridge construction will be timed. Come with prefabricated bridge sections to help aid in the construction

The final equation that will govern competition

Cost = (weight * $801/lb) + Cost + (Environmental Impact * $15/ton of CO2)1.3 + (Speed * $1000/min)

Important Notes:

Bridges must hold 20 lb  for one minute or it will be disqualified
