Judging Criteria:
The winner is determined by a point system as follows:
Complexity - 10 points : The number of purposeful members involved in the design.
Aesthetics - 5 points.
Engineering - 10 points : How much thought is placed into the design, where the connection points are and what member shapes are used in the design.
Workmanship - 5 points : A bridge that is "clean", such as nice glued edges, members matching at connections and nice sanded edges.
Efficiency - 30 points.
Rolling loads test- 20 points.

Heres the problem statement...
Construct a stable truss bridge of span 20 inches, height 5- 6 inches and internal width 4 inches with hollow and solid members (straws and Popsicle sticks) that sustains a minimum load of one kg.
The deck should be essentially made of straws. The loads will be uniformly/non-uniformly placed on the deck. The bridge will also be tested for its efficiency, rolling loads, complexity, aesthetics and workmanship. Paper (provided) can be used for joints consisting of three or more members.
The efficiency of the bridge will be calculated as follows-
Efficiency = Maximum load sustained by the bridge/Weight of the bridge.
Maximum use of straws is suggested as efficiency will be multiplied by the factor 'Number of straws/Number of Sticks used'.
