I am thinking of doing some type of bridge building competition as a
cooperative effort between one of my Physics classes and one of the design
classes in our art department. I know that I did such a thing several
years ago with my students building bridges with glue and popcycle sticks,
but I can't remember the specifics.(How many sticks allowed, the size of
the bridge, the size of the opening in the bridge, etc.) Does anyone out
there have specifics of a bridge building competition they used
successfully?
I would suggest you act as an enlightened system specifier - that is,
specify the desired result and the cost criterion.
Example: Build a bridge to span to pillars spaced 24 inches apart, which
can carry a weight suspended by a sling from its midsection of at least 5 lbs.
The devices will be tested with a bucket of water with incremental water
loads.
The devices will be evaluated at x cents per stick used in the
construction, etc.
The criterion could reasonably be
load at failure divided by notional cost of components.
