the first project that i want to talk about is the bridge project. our mission was to make the sturdiest bridge with the least amount of weight. the bridge was made to specific standards and had to hold 20N to pass. i designed a series of triangle trusses and added in a couple different elements. i made sure that the trusses were strong enough by adding in many short pieces of balsa in each big truss. this distributed the weight evenly thought the bridge, making it able to hold a ton of weight. my design was good. my bridge held over 52 pounds. and my weight to load ratio was reasonable. i learned allot from this project. i now know how to build a successful bridge. i learned how to use many angles to transfer weight. drafting to scale was another element that i have learned. i believe that this was the best project this year, you should definitely do it again next year.
