Neat applet, but it IMMHO is too simple for a proper representation of an 
angled capstan.  If I translate my gut feelings, and some of the other 
responses to this thread, properly, {not a given, for sure} the force 
applied to the top of the capstan is only equal to the force felt by the 
keystick at the bottom of the capstan if/when the capstan is perpendicular 
to the keystick.

  ANY angle of the capstan throws another factor into the equation which 
the applet does not include.  Call out a vector squadron...
