Structural Efficiency

1. This project inlcuded a small group of three where we built a structure out of 12 playing cards and masking tap. the sturcture had to be 8 inches tall and hold atleast 5 pounds. We calculated our structural load based on how much our structure could hold over the weight of our sturcture.

In the class competition we ended up getting third place in overall structural efficiency.

4,395 / 33 = 133.18 structural efficiency

The test results of our prelimanary efficiency was a structure weight of 22g and had an effciency of only 46. We had to make design revisions to our first structure which included going from a rectangle base to a all triangle tower. The new tower worked fairly well but it would have worked even better if we interlocked the stacking of the mini trangle parts of the tower. SO like if we used an interlocking system it might work even better.
