Structures 1 Christian Bravo
Project 1, was assigned to help us learn how to design a static model, that also aligns with the concepts of Equilibrium, load distribution, gravitational forces, lateral stability, tension and compression forces. We were given the restrictions " You will use a cube or series of cubes as dead-weight, and support them with a [combo] of strings/cables and rods." We were not allowed to use glue, as were stated in the guidelines of the project. Keith, my partner, and I used 3 main components to achieve this final model. We used 3 sharpened dowels the sustain the cube above ground, 2 stringed loops held down, in tension by 2 eye hooks, the cube to achieve equilibrium.
Project 2, was design a bridge that could span a 24'' gap and hold a significant amount of weight. Together, Keith and I were able to construct a strong and lightweight bridge that held its own. The bridge took advantage of the concept of triangulation to distribute the external forces that it would later face in the main test. We used internal cross bracing to strengthen the resistance to moment forces as well as adding to the overall stability and strength of the bridge. Along with the cross bracing, we added an additional horizontal pieces to counteract any deformation that could occur from the vertical forces. Ultimately the bridge would fail due to the poor glue connections.
