    Basically I'm stuck now, and don't know what to do.. I don't know what to put for the force of gravity, is it a vector?
    Please help

    Fg = mg

    you have m of beam, 160kg

    then, I think, you have to split mg up into orthogonal components, and see how much of it is going towards Fn.
