Experiment Title: What is the strongest type of beam?
Abstract : We conducted an experiment to determine the strongest shape of beam with the same cross sectional area. We first designing the beams in Solidworks, making sure that they all had the same cross-sectional area, then we had them 3D printed. Then we took two clamps, clamped one of the beams to the piece of wood and put weight on the beam. We found that the I-beam was the strongest by 4.23mm per kilogram. This is true because the I-beam has the highest moment of inertia, a measurement of how much of the area is farthest away from the central axis. Engineers use I-beams all the time to create stronger, cheaper buildings.
