Unformatted text preview: group attempted to build the bridge with the materials that they order, if they were short they must purchase more materials at a higher cost. After building the bridge the group had to make a final design drawing of the actual bridge that they had made. Once all of these tasks were completed the final stage was to test the bridge by adding , weight to the bridge using a hook and a bucket and adding sand to it. Once the bridge is tested and failed the group weighed the max amount of weight that the bridge held up. Our bridge ended up holding about 6.75 pounds including the 1.9 pound bucket and hook. After that the calculations were mad. The cost divided by the load which in the group turned out to be 20414.81. Then the last calculations that were made were the axial load calculations in compression and tension. The compression value was -4.77lbs and the tension value was 3.38 lbs...
