Score: 0.6382

We first tried cutting some parallelograms and noticed that sharp edges created more stress. We added circles (thus the bone looking images) to lower the stresses. We then noticed that an elongated ellipse allowed us to remove more matter without creating a great amount of stress. The shape of the circle and the ellipse were the "best" shapes used, since their smooth or non-existant angles did not allow much stress to build.

How we got there

When we compared the results, we noticed that Gustavo and Daniel's model had much less stress on it. We played around with shapes but both groups agreed to maintain an ellipse in the center. We then tried to remove more mass but that only increased the displacement level. We thus decided to maintain this shape and this mass that offered a favourable result.
