Sample Designs
Mrs. Sangwan and the West Point program told me that triangles were the best way to stabilize a structure. I took that into consideration and made sure I used triangles in my designs. Below are some designs that I came up with before choosing a final design. Also, it helped that our budget was raised by $100,000

Conclusion Questions
Q: How does the type and direction of stress applied affect the selection of the material type and cross sectional area?
A: The kind of stress applied can change in the material you use. For example, if there is not a lot of stress on a certain part, you can use hollow material, but if there is a lot of stress, you want to use carbon steel. More stress means you need stronger material and a larger cross sectional area.
Q: How can the forces of compression and tension work together to make a stronger bridge?
A: In certain places on a bridge, you need compression/tension to make it stronger, and so it can withstand a larger load. If they push the parts of the bridge together correctly, it will make for a stable bridge.
