In europe, where they do many
strange things turbine engines
(thrust and shaft both) are rated
in kilowatts, which is a power
measurement. They do that because
kilograms are a mass unit and it
would be incorrect to say kilograms
of thrust...could say newtons.
Pounds are a force unit, and forces
can do work (work is a force applied
over a distance, power is the rate
work is done at). I think the english
foot/lb system mass unit is a "stone",
but not sure. weight is the measure-
ment mass being acted on by gravity,
that's why in space you are weightless,
but not mass-less.
Anyone want to get more confused?
Just give the word!!!
