Our assignment for week five was to design our own bridge that can span two feet in length and at least four inches in width using K-NEX pieces. The goal of this design is to create the lowest Cost/Failure-Load ratio of the class. To do this, I tried to use as many triangles as possible in my design as triangles are the strongest geometric shape. along with making triangles, I made the angles under the most pressure forty-five degrees to evenly distribute the weight among the triangle. These were my final design images as well as a spread sheet of my designs total cost($140,500).
Throughout the process of designing this bridge, I realized that just the acute triangles would not be long enough to cover the two feet span. because of this my design changed to add two right triangles on the end of my initial design. During the process I learned that the angle constraints are very limited when using basic K-NEX. There is not a whole lot of flexibility in the design process due to there only being a limited number of different pieces.
