|Spaghetti Bridge | Abstract For this assignment our task was to build as a group a spaghetti bridge with the objective of carrying the most weight as possible using only spaghetti and hot glue, meeting the specifications. The bridges will be loaded until they fall. After testing to destruction, the bridges loading capacity was 14.4kg, with an initial mas of 0.840kg. This gave a weight to strength ratio of 17.1 putting the group at 4th/8th position in class. From this it was learned the bridge held 14.4kg which is 140N therefore one Truss held 70N. These calculations helped us understand how our bridge coped with the forces and helped us answer the question of what caused our bridge to fail and where our bridge failed?

This will be done through research, calculations and designing prototypes which will lead to a better final product. Once research, calculations and design have been gathered the bridge will be tested in a controlled environment.
