Team Members


Alpha Squad

Alpha Squad (Jack and John) based their design on the principle that arches are the strongest structure in nature. They started by making a semicircular hole in the center of the design, which created a main arch. Then, to minimize the surface area used, they cut curved, triangular holes into the outside section of the bridge. This made a series of branching archways that spread the stress towards the outside as opposed to downwards. Then, they tested their design with COSMOSXpress and found that most of the displacement was occurring at the center of the top crossbeam and most of the stress was concentrated in the inside corners. To minimize the displacement in the center, they thickened the center of the top crossbeam by reducing the radius of the circle used to create the main arch. To keep the stress from building in the inside corners, they used the filet tool to round off the corners. The resulting design is shown below, and has a score of 1.498662E-6 A3alpha.jpg
