Presentation:

UW stepped up to the stage and began their “Rock Solid” presentation.  Three male and one female team member gave the talk and the team used a combination of computer projection and easels to supplement it.

The team promoted the effort as a sales pitch and began by describing their hull design.  They described the mix design process, test procedures, and boat construction.  Details were given on the composite design… transverse pre-stressing, free fibers, and continuous reinforcement.   A reciprocating loading device was used to simulate the service loads.  Steps taken to formulate a good bond between the matrix and reinforcement were described and the management approach was covered.

The judges asked the team how was transverse pre-stressing accomplished?  Could you elaborate on your management strategy and how you employed your knowledge base?  What was the cross section selected for your analysis?  Was it located at a rib or where no rib was placed?  What is your expectation for this competition?

The judges then returned to questions on section analysis.  Then they asked if pre-stressing cables were used in the ribs.  Were quality control techniques used during construction and what tools were used during fabrication?  What is an optimal curing condition and how does this impact structural performance?  Would a safety factor be appropriate and what would it be?  How did you determine the solid portion of binders such as Latex?

Overall, the team did very well and lived up to the theme chosen for their boat... Rock Solid!  What more can I say.
