Span Strength due March 20

You will build a bridge using foam core and glue. Your bridge must span a 2' gap, be at least three inches wide, and there must be a place where we can stack weights. Your goal is to build a bridge that can bear as much weight as possible. Consider strength and beauty when you design your bridge. Your projects will be strength tested during the critique, and the student whose bridge can hold the most weight will win a prize.
