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.
