Currently BEING REVISED Bridges Phase III: The principle purpose of this third portion of this project is to actually build and load test the spaghetti bridge that was designed in the 1st and 2nd portion of the project (Phase I & II). Based on the design rules, the the bridge was designed to support the maximum amount of weight possible. It is our intent during this phase of the project to document the entire process of building the bridge and load testing. Please see the "Summary" for additional information regarding the specifications of the bridge as it was design and the method that will be used for load testing. DivaEngineer Syed Sami Ahmed Erik Smith Kevin Saunders The focus of the project is to actually build and load test the pasta bridge that was design in the previous project. In addition to that, we will document the entire process in an attempt to create a tutorial for the process/strategy of gluing the pasta pieces of the bridge together to create a strong bond. This tutorial can potentially be used as a source of information for future teams attempting to design a pasta bridge and eliminate the frustration of trying to figure out the correct method of bonding the pasta pieces in such a manner that will actually contribute to the overall strength of the bridge. We have used previous design max loads as a standard for our design and will follow the plans created for putting the bridge together. Each week our team will meet to work on the completion of the build as it will take quite a bit of precision to get it done. The progress of the project can be viewed via the links below of the Team Weekly Reports. Team Weekly Reports Week 0 (November 7 - November 13 , 2011) Week 1 (November 14 - November 20, 2011) Week 2 (November 21 - November 27, 2011) ::Week 3 (November 28 - December 4, 2011) IN PROGRESS This is a simple pony truss, the easiest to make with spaghetti. Esmith1993 joined for the final 4 weeks of the project and caught up with the idea of a spaghetti bridge. K.saunders joined last second to contribute his findings on failing force of spaghetti and linguine in relation to length of noodle. DivaEngineer and Sahmed1890 already constructed pieces of the spaghetti bridge and were just continuing construction.Sahmed1890 used another piece of wood to cut through and make another load support. He then sketched a line on the wood to determine the dimensions of the wood according to the rules. He used the saw and made the wooden load support. After wiping it of the dust he then placed the hook in it and finished with it. As a result of the experiment, as the length of the noodle decreased the strength of the noodle increased. This can be used to better our understanding of why good bridges work and bad bridges fail. Because the torque is smaller on a shorter noodle it can withstand more force and resist twisting. Decisions made: Zita Spaghetti Individually created truss's and bring them together as a group to critique Strategically place hot glue where extra support is needed. Link to Glue gun tips Link to Zita Spaghetti Link to another long spaghetti Google Sketchup 123D Four week project; approximately 7 hours a week 4x7=28 hours Approximately 28 hours spent on this project Because spaghetti noodles are so fragile and thin. You must first layout the project with wooden components and once your wooden blueprint works sufficiently you can then transfer over to the noodles and begin the construction of the actual spaghetti bridge. Many spaghetti noodles will be wasted without proper planning. Next group should use either google sketchup or 123D to construct a blueprint of possible bridge structures, and either proceed to make a spaghetti bridge or use balsa wood as a starting point.a
