thats a really good question
my first reaction to this would be to say if i saw 2 people lifting the same weight then they were equaly as strong as each other
but if you look at it mechanicaly then if two machines were lifting the same weight but one had to lift it higher than the other then that machine would need to be more powerfull than the other to do it
or scientificaly it would be Force = gravity (9.81newtons) X mass (weight lifted) X length (height of lift in meters)
which would tell you that more force was used to rais the weight higher
i think the transposition is right on that formular could be wrong my mind has gone numb :?
