Introduction: Design Project “A” involved the design and construction of a bridge from the set of given materials. The completed bridge was tested for strength with the help of the Baldwin testing machine. A few new physics properties were introduced beforehand, and were meant to be used as guidelines for the bridge design. Metal was said to be better at handling tension force while wood was better suited for compression. This means that on the top of the truss bridge, where the structure was going to be compressed, the best material would be wood.

Unformatted text preview: On the bottom, the strip of metal would increase the tension force needed to break the bridge. Also, a diagram of a triangle was drawn, and it could be seen that a longer base and a skinnier top would be a stronger design then a skinnier base with a longer top. With these ideas in mind, the materials were put together in the time of two class periods and prepared for the crusher Design Parameters: The materials for this project were one one inch by two inch by fourteen inch block of Clear Redwood , one two inch by fourteen inch twenty gauge galvanized sheet of metal, two six inch zip ties,...
