    I will gladly critique your thoughts. Start wth the definition of "ima" (Ideal Mechanical Advantage).

  • physical science -

    It is the the MA of a machine without friction. MA being the ratio of the output force to the input force.

  • physical science -

    yes it is with out function because of the out put of force
