If a lever has a mechanical advantage of 6, and the distance from the fulcrum to the load is .05m, how far is it from the fulcrum to the effort?
I think I'm supposed to use some sort of kinematics formula, but I'm really confused.

  • Physics -

    The distance to the effort point to the fulcrum is six times farther than the distance from the fulcrum to the load.

    That comes from the definition of mechanical advantage, or
    force ratio = lever arm length ratio

    oh, thank you!
