Construction

Description

            The construction of this bridge will occur in segments. This project consists of 7 parts and 2 sub-assemblies. The first segment of construction is to assemble both sides of the truss. The next portion of the build will be to connect these 2 trusses together using cross segments. Following this step, the road deck will be installed creating a surface for the simulated car to cross. Lastly the bridge will need the articulation tower installed in order to be able to move up and down. This section contains parts that  will be printed using an at home 3D printer.

​

Parts

            This project in particular has the benefit of having a material constriction which means that most parts will be similar process for manufacturing. For the truss structure, the 3 different dimension Members have been purchased in those dimensions at 3 feet in length. They will then be required to be cut down into the appropriate lengths depending on the required length for that Member location. The articulation tower is composed of 1” x 1” balsa wood segments which will house the crank for articulation as well as the string and pulley that will be transferring the force from vertical to a vector at 10 degrees.

 Manufacturing Issues

                Issues with manufacturing would come from things such as the 3D printing process not being able to accurately produce a part as small as the ones for this project to any degree of accuracy. This could cause a rough spin within the rotation and create unwanted friction within the system. Another manufacturing issue would be the glue not creating a proper connection between members leading to a premature failure.
