2.4.1 Structural Design
Research Summary
Before I even started this project I knew very key things that are needed to build a bridge, one of the most important being that triangular shaped trusses are the strongest type of truss design, also that the bridge has to be able to withstand a load, in this case being the truck. I also had experience creating strong trusses in a previous project which you can find under Principles of Engineering "Trusses".

Final Design Justification
I chose this truss design because it was under budget and it was strong and held the force of the truck, also I went for a different design while keeping a basic strong structure, then I added 2 vertical beams for support of the overhead truss which did help with the support a lot but also gave a new and visually appealing design.
Conclusion Questions
1. The type and direction of stress effects the material type because you may need a stronger material, or a thicker member to increase the cross-sectional area to support the stress for that member.
2. Tension and compression forces can work together by almost evening out and distributing the weight of the weight coming down onto the bridge, which in turn makes the bridge stronger.
