IntroductionThis report details the process and data used to determine the design of the final truss that wasbuilt as well as the predictions for how the truss should perform theoretically. The truss designthat was picked as the final was almost an entirely new structure in comparison to the onespresented in the preliminary design report. However, the overall structure and internal shapesformed by the members of the truss follow similar patterns to what was seen in both of theoriginal designs. Overall, the two main data points used to determine which truss would be built were thecalculated maximum load that the truss could bear and the load to cost ratio of the truss.Theoretical maximum load was heavily considered because it is the main individual data pointthat predicts how well the truss can perform experimentally. A truss’s primary purpose is to beable to bear some sort of downward applied force. Therefore, maximum load was the data pointmost heavily considered while different designs were being drawn and while determining whichof the designs would best accomplish the goals of the overall truss design project.Of course it is also very possible to design a truss that has the potential to withstand alarge loading force, but ultimately turns out to not be ideal because of factors that prevent itsconstruction such as complexity or cost. A high complexity in design was avoided during theprocess of actually constructing the various truss designs. Consequently, none of the considereddesigns would have been too complex to accurately assemble. On the other hand, cost and load
