Query: Flexibility of Bricards planar linkages and other structures via
  resultants and computer algebra   Flexibility of structures is extremely important for chemistry and robotics.
Following our earlier work, we study flexibility using polynomial equations,
resultants, and a symbolic algorithm of our creation that analyzes the
resultant. We show that the software solves a classic arrangement of
quadrilaterals in the plane due to Bricard. We fill in several gaps in
Bricard's work and discover new flexible arrangements that he was apparently
unaware of. This provides strong evidence for the maturity of the software, and
is a wonderful example of mathematical discovery via computer assisted
experiment.
