4.) When we were doing the Method of joints hand analysis, we realized that the numbers we were finding were not identical to the numbers given to us by the online Bridge Designer. This worried us, but then we also realized that there were no units given to us by the online bridge designer and this cause us to think that in order to get those numbers it would just come down to scaling the numbers we calculated. The numbers, we found, were the same in the end but just differed by a common multiple and only needed to be scaled to be identical.

6.) Through this analysis I learned that when the angle is decreased, the force also decreases. This would cause me to want to build a bridge with smaller angles to decrees the force on each joint. By doing this I would improve my bridge design, and ultimately cause it to hold more weight.
