    Hi guys.

    I need a few equations to complete a table.

    I am given numbers for:
    Fg (N)
    h (m)
    Fa (N)
    d(m)

    and I need to find:
    Work Output (J)
    Work Input (J)
    Effeciency

    If anyone has those three equations I could use it would be greatly appreciated.

    Welcome to PF nicholz,

    We need some idea of what your talking about first. Secondly, the forum guidelines say that you need to show some working and/or thoughts before we can assists you. So what ideas do you have? Have you looked at your class notes?
