Bridge
Division: B & C – Middle School & High School
NC Essential Standards Alignment:
Grade 6, 7, and 8: Goals 1 and 2; High School Physics 7.P.1, 7.P.2, Phy.1.1, Phy.1.2, Phy.1.3, PSc.1.1, PSc.1.2
Event Rules: See the National Rules Manual
Event Score Sheets:
National Event Page: Here
Required Materials: All participants must wear eye protection (Category B) at all times.
Clarifications: None
Description:
Teams will design and build a Bridge (Structure) meeting requirements specified in the rules to achieve the highest structural efficiencies
Materials:
The event supervisor will provide the Test Apparatus and tools/materials for measurement.
Scoring:
High score wins. Score = [Load Score (g)/Mass of Structure (g)]*Design Log Penalty Multiplier
Common Mistakes:
Not meeting requirements specifed in rules
Recommendations:
The goal is not to build the strongest bridge. It is to build the most efficient bridge. Most winning bridges will break before holding 15,000 grams. In other words, you want to build a bridge as light as possible, but capable of holding a significant amount of weight to achieve maximum structural efficiency.
