5 lbs of steel, plus a large sheet of 1/8" polycarbonate. Has anybody build the full device, and if so, are the forces necessary to lift it consistent with what we've been told to expect? I'm thinking 2012, of course. The difference between teams who had access to the full and accurate field and those who built the simple version of the bridge were, well, the difference between winning and losing, mostly.
