Tower 2 results

Tower 2 weighed 4.905 lbs and withstood 19,867 lbs of force before it succumbed to the pressure. This results in a strength to weight ratio of 4,050.36 lbs/lb. It was the heaviest tower and withstood the most force of all the towers tested however it did not have the highest strength to weight ratio, but it was the second highest.

Balsa wood tower 2

Second design with some (hopefully) improvements. Built with high density balsa wood it has much more bracing, but also much more weight so we'll have to wait for the test to see if the compromises pay off. Bathroom scale weight is 4.8 lbs so it needs to take 17,150 lbs of force to better the first design.
