KN is this acurate?

[munkymadman]

i didn't even get a chance to take it out of its bag

[Tony Croft aka hamadryad]

amazing isnt it, all this and we still remain unclear what KN is!

[munkymadman]

embarassing really, i never really know if i'm overloading something or not. its all too much to calculate while working. i am astounded by how strong equipment is, even the lightweight stuff. i've broken rigging points but(knock on wood) never rigging gear. i often look at some gear and think is this knackered(just because its not all shiny anymore) or has it got years left in it.

I am amazed that no one has been able to clarify the KN issue!

kN ("K" lowercase, "N" uppercase) is Kilonewtons, or a measure of force. 1 lb = .00444822162 kN.

[Tony Croft aka hamadryad]

25 kN is apparently 2.5 ton to a few decimals

in my defense(for my recent blonde moments) i have always been aware of the tonnage with kN. i see 2000 and i think 2 tonne. very little equipment goes below a tonne in strength(bar the plastic crabs). very little goes above 10 tonne so i always see the first number '2' in 2000, i think two small cars, thats alot. thats how my basic brain works, association. and i'm afraid i'm guilty of not really considering the swl. even though it annoys me that my grcs thing is rated in pounds(can't calculate that, without a converter

The 1lbs issue is an american thing, thats why i wish we would just accept europe and get on with it, we are far from the yanks!

A mass of 1kg (sitting on the ground) exerts a force of (nearly) 10 Newtons due to the force of gravity.

 

So when reading a pulley's rating as 22 kN - you could 'imagine' an approximate rating as 2.2 tonnes.

 

Does this help at all, Hama?
