Today we started on our bridge project. We ran compression and buckle tests on our components. The tests we ran focused on measuring the compression and tension strengths of the hot glue joints connecting two tongue depressors. We found that the compression strength is weaker than the tension strength for the joints. However, the measurements might not be correct due to uneven gluing. After we were finished with the measurements, we began designing our bridge and proceeded to make a simple prototype (shown).
