bridge building

We just finished the wrap up to the bridge building lessons that we have been completing over the past few weeks. After learning how to calculate truss forces and moments we were able to create a stronger bridge. To test strength of the bridges, magazines were placed on the bridge until the bridge collapsed. My team's design was one truss( since we could only use 3 folders making a true bridge with double truss and a connector would go over the folder limit. The triangle design held but gave in on the asymmetrical side by the 12 magazine. At least it was better than the first time around.
