During the building process, I learned about how specific structure or additions to the bridge can make a big impact on the stability of the bridge. Especially when we later tested the bridge, I was able to see how parts of the bridge function in supporting the weight and the whole structure. During the testing process, I learned from what my peers were doing that distributing the weights properly can also be really important. Properly distributing the weight across the whole board and making sure to decrease the weight as the bridge starts to sway are crucial in determining the overall success rate of the bridge.
For our bridge, since our structure involves the difficulty of bending the wood into a semi circle shape, there are many risks involve. It took us many tries and wasted many material to get the semi circle done. Although they were still not perfect, as the some small cracks in the middle probably affected the overall stability of the bridge, they were strong and thick enough to provide a decent amount of support. For the members of the bridge, when we were trying to cut it, many small wood pieces fall out and created many cracks and empty spaces within the wood, and this could be another factor that causes the members to break. I think the main thing that my group failed to do was jointing the parts together, because the two semi circles came out in different sizes so the members were not able to joint perfectly. If we were to do it differently, we would have calculate the measurements more carefully and be sure that the material (wood) were cut with more caution.
