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.
