670 Kn

[kopend]

hi we are a bit confused over how much toone force 670 kn is


is it 101 tonnes or 67 tonnes and what is the tonne force ???

[Calibax]

one tonne-force = 9.81 kN

[Teddio]

67 tonnes force approximately. Remember that the tonne (1000kg) is a unit of mass.
A mass of 1000kg in the Earth's gravitational field of 9.8 Newtons per kilogram will exert a downwards force of 9800 Newtons.

what's a toone force? Is that a Newcastle SI unit?

[Peter Pedant]

Oh god are engineering courses still doing this ?

hopelessly confusing mass and force

kn in your question ( could be kiloNewton ) or Kg (killgram)
The answers differ by 9.81 ( eff equals em ay and all that)

One machine in the good old days was calibrated as kg-f/ sq in

what is tonne force ?
tonne force is a made up unit favoured by engineers and other low life whereby they say it is the force exerted by one thousand kg.

make a diag, square will do, hang in there a mg arrow
apply newton - F = ma and here F is what you want - the force exerted by one tonne m is 100okg that would be one tonne
and ay is gee - 9.81 ms-2

knock it together and there you are.One tonne force in Newtons

[ remember one newton is the force rquea to accelerate one kg mass by one metrepersecpersec ]

repost if necessary

we cant answer unless you tell us whether kn is kilograms or kiloNewtons

[ToraToraTora]

engineers are low life, peter? odd statement to make.

[Peter Pedant]

at uni they were said to be all failed computer programmers

but I am sure it was a turn o f phrase

others - engineers mostly - said they were great in bed !
