the longest, but least solid, by far.  The first two bridges
barely deflected since they were the same basic construction
(the metal u-sheets connected together).  The final bridge was
more outside of the box thinking: it used the battery charge
cable to act as a flexible bridge.  However, that ended up
failing as the weights caused the cable to sag and the outer
edges to collapse inwards.   We attempted to make a SAM
animation of the bridges deflecting under the weight, however
the first two bridges did not deflect enough and the third
deflected too much too quickly.  The rest of the day we worked
on various connection types: figuring out the best ways to
connect LEGOs, TETRIX, and everyday objects.  We learned that
LEGO axles and TETRIX shafts are the same dia
