Practical limits of a lever

If one is only considering the mechanics of a lever, what is the maximum
a physically possible lever can lift ?

Your only limit is the physical strength of the lever arm and how high you want to lift the object.

Thanks Russ, i understand this , i am more interested in material science
and the limits it imposes on a lever.

There are many factors which invole "limitations" to a lever.
Perhaps the most constraining is the limit of covalent bond strength within the molecules of the lever itself.

Wolram - I suspect you are nudging at the question of whether having a circular force (torque) has any significance on the material limits?

Yes, better worded than my inept post.
