Span Strength (due Dec. 16)

Each of these bridges held 100 lbs!

Assignment
You will build a bridge using only foam core and white glue. Your bridge must span a 24" gap, be at least 6" tall and and 8" wide, and there must be a place where we can stack bags of clay that are 6" wide. 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.

Dec. 2: You will be given 2 sheets of foam core in class. Work on your plan, figure out how to cut all of the pieces you need out of your foam core.
Dec. 9: Come to class with white glue and a sharp knife & your work-in-progress.
Dec. 16: Critique of bridge projects in class.

Here is an example from last year so you can see the setup during critique. The pieces of wood screwed to the side of the table extend down 1'.
