daN

[sharpey1]

hi what is 180 daN in kg or lb

 

thanks

[LoKi_79]

it is 180 kg.

 

[daN = decanewton = 1.02 kg]

daN expresses the force that the line can take......all forces are measured in Newtons.

 

If you convert it to mass in kilograms you need to work on the basis that a mass of 1Kg has a weight on Earth of 9.8 N

 

So a decanewton is basically 1/10th of a newton so it gives an easy conversion

 

500daN...........500Kg load

 

F/O Kite.......................was this part of your science homework?

By of a strange way to present your lines strength but hey ho:)

[LoKi_79]

careful what you say - the SI unit of force is Newtons, but you can measure it how you like

Most of the European manufacturers label their lines in DaN. It isn't quite the correct SI unit but it is more accurate than kg, which is as already stated twice, a mass not a force.

 

If you use your lines on the moon, they will still break at the same amount of DaN (or N or kN for more normal engineering orders of magnitude) but you could suspend a lot more kg of mass from them. Of course since we mainly fly at sea level it makes no difference in practical terms!

 

The first 2 replies are quite correct, I wasn't going to respond because they are already there, but then MadAndy inspired further explanation!

I know my physics but not everyone does.

 

Some poeple..most I would say, would be more at home with seeing lb's or Kg's as a breaking strain.

it actualy makes more sense [to me] to use a force rather than a mass. but because gravity is (fairly) constant, we can use mass and force interchangeably. indeed kilogram-force is can be represented by kg:
