Bridge-a-roni Score Sheet

Official Rules: Bridge-a-roni
Clarifications:

 

Description: This is building event. Prior to the competition, teams will design and build a pasta bridge capable of supporting a load of up to 10 kg. Specific requirements are outlined clearly in the official rules.

Materials: Teams must bring their bridges and safety glasses.

Scoring: High score wins. Scoring for this event is based on efficiency. The following formula will be used:

Score = Total load supported / Mass of Bridge

Load supported and mass of bridge are both measured in grams. The total load supported includes the mass of the bucket, loading block and chain, and sand, for a maximum of 10,000 g (10 kg). Even if the bridge holds more than 10,000 g (10 kg), only 10,000 g will be recorded.

Bridges that fail to meet one or more of the requirements will be ranked in a 2nd tier beneath those that do meet requirements. Bridges that cannot be tested at all will be ranked in a 3rd tier below those that can be tested.

Ties will be broken in favor of the team with the lighter bridge.

Event Hints:

  1. Hot glue dries/hardens quicker.
  2. Triangles are a construction engineer's best friend.
  3. Taller is better (to a point of course).
  4. Make a full-size pattern of your bridge. Build bridge on pattern. Be exact!
  5. "Spot" glue and don't add excessive adhesive weight.
  6. Joints should be "overlaid" not "butted".
  7. Cut off excess pasta and glue after assembly.
  8. Use bridge design software. Search the web for other ideas and designs.
  9. Build and test A LOT. Each iteration will get better. Design, test, and refine.
