Interactions may happen from one timestep to the next, e.g. the axle may
fall during the first timestep, but the small distance it falls may cause
a reaction during the next timestep.  That would be true if it
"communicated through position," i.e. if gravity caused the axle to
rotate, and the rotation *angle* caused the gyroscope effect.

You might need a really small timestep though.
