        Designing an Earthquake-Resistant Bridge

        Now that you have finished the activities in this course, it's time to share your learning. Your team will design, build and test a bridge made completely out of PASTA (and some glue). Document your trial and errors throughout the experiment using a flip camera. When you are finished, link your movie on the Final Projects forum. Pasta Bridge

        Challenge:
        The bridge over Foamy Falls collapsed during a flood. Now, the town of Penneville needs a
        new bridge. To buy the best bridge for the money, the Town Council interviews several civil
        engineering companies. Each engineering team must prepare a detailed list of the materials
        used, a budget, a set of design plans, and a model of the bridge.

        The Town council states that the winning design must be safe and inexpensive.

        Safety requirement: The model bridge must span between 40 - 50 centimeters long. The bridge must support a baseball, and the ball must be able to travel across the bridge from end to end without getting stuck in the center. We will do the final test by attaching a bucket to the bridge and seeing how many coins we can add to it (up to 30 coins).


        Directions:
        To get started, watch these two videos. Jot down ideas and share them with your group about what you think would work best in your pasta bridge design.

        Bridge Building Contest Rules

        1. The bridge must be built according to the bridge building code, using only materials supplied by the CardboardPastaGlue Company.

        2. The bridge will be judged by the quality of the building plans (Google SketchUp), as well as the strength and the durability of the bridge.

        Judging of SketchUp Design Plans will be based on
        • design detail
        • cost of the bridge
        • how well the finished bridge matches the plans
        Judging for the strength of the bridge will be tested by
        • placing a bar across the middle of the bridge with a bucket suspended from the bar.
        • the teacher will add weights to the bucket according to the project director's wishes.
        • the last weight that the bridge holds for 30 seconds without touching the cardboard (except at the bridge foundation) is the weight recorded for the strength of the bridge.
        Judging for the durability of the bridge that can withstand
        seismic force will be tested by
        • shaking one table leg while a baseball is rolled from one end of the bridge to the other.
        • the ball must be rolled two times across the bridge.
