Weak link for PW-5

[Nyal Williams]

ThePOH calls for a maximum strength of the weak link to be 700 daN.
Does anyone know what that is in pounds?

[Dan Babcock]

Slightly less than 1575 pounds. It is more accurately, 700 X 2.248 pounds.

dekanewton or decanewton (daN)a fairly common metric unit of force equal to 10 newtons.
The dekanewton is equal to 1 megadyne, to 1.019 716
kilograms of force (kgf) or kiloponds (kp), to 2.248
09 pounds of force (lbf), and to 72.3301 poundals.
In engineering, the dekanewton is a convenient substitute
for the kilogram of force or kilopond, since it is
nearly equal to those units.jeff

OK all you mathematical converters, aren't we asking
about a WEAK link ?

No, but we can figure it out.

daN will be "deca Newton". A Newton is the force required to accelerate
1 kg at 1 m/s^2. Gravity can accelerate a kg at 9.8 m/s^2, so a daN is
near enough to the force required to pick up a 1 kg weight.

So 700 daN is near enough the force to pick up 700 kg (1500 lbs). Which
means it'll give a PeeWee well over a 2G jerk, and pick it up with ease.

Which will be great comfort to me, I'm sure, the next time I'm in a
PeeWee dangling on a rope under the big Pawnee as it does a banner
tow-style climbout.
