Solution
Obviously, decisions need to know the breaking strength of the rope.
Cable diameter 10 mm typical breaking strength of the order of 55-65 kN (worse or better). Roughly, one kN corresponds to 100 kg mass load. So consider that it is 5500-6500 kg and divide by specific gravity.
And it was possible to take from the table "Breaking strength of the cable, kg" value "5210", divided by 450 and multiply by 9.8 ?

you the dimension of the formulas in the school check has not been taught?
You take the value from your table is already in kilograms, not in Newtons, divide by specific gravity in kilograms per kilometre, and get miles. If you multiply by 9.8 Newtons per kilogram, get a km√óN/kg. what is it? - Mark.Kub commented on June 14th 19 at 20:56
