A Block
Earlier in the year, we had to construct small bridges out of 1/4" thick strips of balsa wood. We were only given a certain amount of wood and we had to use glue to put it together. Each member of the class designed their own bridge to scale before they began construction. Students were graded on how much weight their bridge could hold and how light it was. My design was very conservative in terms of the amount of wood used which made it very light, but as a result my bridge did not hold very much weight. This free-standing bridge was difficult to glue together and most of the time I needed things to hold it up while the glue dried. If I were to do this project again, I would design my bridge so it utilize the amount of wood given so it will be stronger. During the project, I learned about different types of trusses that are used in life-sized bridges in today's world, although I never really understood which ones would work the best for this situation. For the most part I just put a bunch of different trusses in my bridge and hoped it would work well.
