To figure out which trebuchet we would develop as a team, we broke up into two groups. Each group researched, designed, and built a scale model by laser cutting acrylic. Whichever trebuchet was able to shoot farther using similar material constraints would be deemed the winner and would be developed further. text/html 2012-04-18T01:12:38-04:00 http://dap.cooper.edu/doku.php?id=start:classes:principlesofdesign:pumpkinchunkin:start:acrylic_matt&rev=1334725958&do=diff Acrylic Prototyping text/html 2012-05-08T00:07:43-04:00 http://dap.cooper.edu/doku.php?id=start:classes:principlesofdesign:pumpkinchunkin:start:alex_novoselov&rev=1336450063&do=diff Alex Novoselov My name is Alex Novoselov and I am studying Mechanical Engineering at The Cooper Union as part of the class of 2015.
