Structural Efficiency

1. For this project, me and a group of 3 built a structure out of 12 playing cards and tape. We weighed the structure and preformed a stress test until the structure collapsed.  Our structure was able to hold over 55 pounds and only weighed .1 pounds

3. Our structure was by far the best in the class.  It was able to hold over 55 pounds without collapsing

4.  Our efficiency rating was 513

5. Prior to the final testing, our structure was extremely strong.  We had an extra card that we used for base support and it made a large difference.
