The force you addressed is a significant factor and a big advantage for the
planetary gear set.  But what I was addressing was the discussion on point
contact force at the gear tooth contact patch.  The point was made and
conceeded that the small diameter of the planet pinions negated part of its
advantage of having multiple gears in mesh.   This is not correct.  Here's
another clue -  the diameter of the planet pinion has virtually NO EFFECT on
this force.  The big prize is still offered for the first to explain why.
