Doesn't that depend on how BIG the rope is?
It's an interesting thought problem -- how big would a Dacron rope have
to be to have the 4000 lb breaking strength (assuming a small tower) of
typical EHS or Phyllistran tower guys? Second thought problem -- how
much would such a mongo Dacron rope cost per foot, compared to EHS or
Phyllistran?
Any mechanical engineers out there?
Certainly one can't replace 3/16" EHS with 1/2" Dacron rope. They aren't
even in the same league strength-wise.
