Warren, et al:

I must admit I find this quite confusing.  So, some of this may in fact be
wrong.

I was not the one that brought up the 350# thing, but it seens to me that
if
each cable of a bell crank had a 175# weight hanging from it, then the
tension on the bellcrank pivot bearing would be 350#, which I think is
what
the other guy was saying.

As far as the unequal length arms go, A Cessna 140 has unequal length bell
crank arms on the aileron bell cranks.  The shorter arms (If I recall
correctly) are connected togther by the carrythrough cable.  The longer
arms
are connected to individual cables that go to the yokes.   If you set the
yoke cables up with 30#  (Cessna says "about 30 lbs") and then measure the
tension on the carrythrough cable, it is higher due to the leverage
advantage
from the shorter arms.  I know this is true because I lost a bet on it...
