Presentation:

Michigan Technological University represented the North Central Conference and made their fifteenth national appearance.

Tech relied on 4 people to make their presentation; 3 men and 1 woman. The presenters were dressed business casual. The team used 1 screen; there were 2 animations.

The team based their theme on the Japanese culture. They began their presentation with an introduction to their theme and the inspiration behind it.

After a brief team introduction, the team members outlined their dual captain management scenario. Then, they explained what procedures were followed and how safety precautions were taken.

The team described their hull design and outlined its attributes. They mentioned that they tested a prototype to uncover and correct design flaws.

The team discussed their structural analysis. They mentioned the cases studied and provided the results of their test program. Then, it was on to mix design.

The team explained how they added new materials to improve the design and specified the degree to which this was done. They provided a composite comparison before moving on to the analysis of their reinforcement.

The team described the challenges that they faced and explained how they incorporated a time buffer to stay on schedule. After outlining form and canoe construction, the team brought their presentation to conclusion.

Questions and Comments:

  • What is the rule of mixtures?
  • Do we usually use the rule of mixtures for reinforced composite design?
  • You used recycled water. Why do you think that your concrete strength was lower as compared to when clean water was used?
  • Why did you choose a linear distributed load to model your paddlers as opposed to a point load?
  • How did you apply quality control while fabricating the grid used to reinforce your canoe?
  • Would you do fabricate your own grid again next year?
  • How long did it take you to do this fabrication?
  • How did you formulate your critical path?
  • How does the block coefficient relate to the hydrodynamic performance of your boat?
  • You used a 3D printer to create tools. In retrospect, is there anything else that you could use your 3D printer for in the future?
  • Can you elaborate on why your hull shape helps to improve performance?
  • What restriction in the rules most prevented you from building a better product?
  • How did you determine that one layer of reinforcement would be sufficient?

Commentary:

The presentation went very well and the team addressed the judge's questions nicely.
