Bridge Competition

The purpose of this project is to demonstrate how bridge structures of different sizes and configurations behave when subjected to vertical loading. Your goal will be to build a bridge to withstand a vertically-placed weight. Each bridge will be subjected to a vertical weight. The weight will be increased incrementally until failure. Failure is defined as any members becoming detached or disconnected from each other or from any connector pieces, as well as any member breaking.

Each team is provided with (1) K’nex Building Set upon registration. The K’nex kits must be turned in at the end of the competition.

Each team will be assigned a time to compete. This time will be given to you when you check in the day of the competition. The team will have a maximum of 30 minutes to construct their bridge. The bridge will be weighed, and the weight will be recorded. It will then be loaded and the maximum load at failure will be recorded. The load will be applied at the middle of the bridge.

Participants may bring up to 3 pages (front and back) of hand drawn or computer drawn diagrams, schematics, etc.  PHOTOS ARE NOT ALLOWED!

 

Rules:

  1. Maximum team size: 3
  2. DO NOT glue or permanently adhere pieces together
  3. All pieces must be detached from each other prior to construction
  4. Bridge must span a 10” chasm
  5. Bridge must have width between 4” and 6”
  6. Bridge must have height between 6” and 10”
  7. Maximum 30 minutes assembly
 

Judging Criteria:

  • Bridge must be assembled in 30 minutes or less
  • Scoring: (Maximum Load at Failure) / (Weight)
