Report

α Squad

Α squad.jpg First and foremost, we wanted to use as little material possible. From studying the mickey mouse bridge, we saw that the center of the bridge, where all the material was cut out was very weak. We decided that we would try the opposite approach by filling in this center portion. However, we came to realize due to how the load was being applied and where the bridge was clamped down, the base of the bridge offered very little support. Thus, when we moved on to meet with our *&Omega cohorts, we easily agreed on a number of aspects of our joint bridge.

Thinking Process

We had a lot of preliminary designs and discussed some possible techniques for the bridge. At first, we had thought of tweaking the mickey mouse bridge, but since that design didn't go so well, we decided to work on an entirely new approach. Instead, we had concentrated most the material in the middle and the bottom of the bridge. This had produced a design that was both efficient and sturdy.


Design Process

We used an iterative design process where we would make a change based on what we saw as a weak point in our design, retest the bridge, compare the old design with the new, and repeat. We also started with a few very different designs to look at which started off from the best position. We used some principles in our design such as avoiding sharp edges and not using excess material to support bad designs. As a group, we eventually decided on making the base of the bridge nothing more than a think strip of material in order to really decrease the surface area and increase our score.
