Matt, Ryan, Brian, Zach, Chris, Steve
Chris reminded the group about midterm presentations, said he would like to review a rough draft if possible. Group showed Chris an animation of the mechanism created with ProEngineer. Chris was concerned about lack of adjustablility in animation, Brian said design still needs to be updated to show adjustability mechanisms. Chris suggested using a factor of safety between 2 or 3 for stress and fatigue calculations. Group would like to measure Mirage Drive flippers to determine max force possible. Matt was able to determine the Mirage Drive uses anodized aluminum box tube with some sort of coating. Steve arrived approx half hour into meeting. Group again discussed large side loads and possible hinge failure due to side impulse loads. Steve again emphasized adjustability required for limited range of motion or one-arm users. Steve would like to use handle attachements from www.topendwheelchair.com. Steve announced Med Trade National Design competition, suggested our design may be eligible. Steve said that we can drill through the kayak for additional strength if needed. Steve suggested adding various implementations of springs for "break-away" ability due to large impulse side loads. Chris suggested this may be an idea for a new project or second generation. Steve will be on vacation from Thurs March 5 until Sat March 21.
