Analysis of Tubes
After reducing the feasible tubes to 2 options (hollow round tube, and hollow square tube), some research and simulations were conducted to assess the properties of each option. The dimensions of each tube were kept the same to for comparison purposes: 10in long tubes, 1x1x1/16in square, and 1x1/16in round.

Recommendation for MSXV
...
Ideally a hybrid of both tubes could be used to maximize the benefits of both types. If a compromise of both cannot be made and it’s one or the other, asses assess the benefits of both based on the team’s goals/priorities, and the closest tube to achieving our goals should be picked (e.g. lightest = round, easiest to integrate with other subsystems = square).
