SECME – Balsa Bridges Presented By: Michael Olka P.E.
What are the teams responsible for building? The superstructure only The support is supplied at the testing site
Balsa Size Restrictions Maximum Member cross section is ¼ by ¼. Students are allowed to laminate smaller members to create larger ones, however this built- up section may not exceed ¼ by ¼. ¼ ¼ ¼ ¼
The Supplied Support 38 cm 6 cm 10 cm
Testing Machine Leave the center open
Ranking of Bridges The Bridges are ranked according to the Strength to Weight Ratio. Not the Maximum Load. *The higher the ratio the more efficient the bridge.*
Example of the Ratio Bridge A: Weight: 100g Load: 45,359g (100lbs) Bridge B: Weight: 50g Load: 27,215g (60lbs) SWR: 453.59SWR: 544.31
