Homework Help: Forces and Vectors in Equilibrium

  1. Jan 1, 2012 #1
    1. The problem statement, all variables and given/known data
    So I am at a loss at the moment my brain is not functioning....
    Ok so we had to set up a pulley like system with straws, string and paper clips. The assignment was to do this and gather data, they didn't say what data to all gather.. I collected number of paper clips in all three locations Left, Middle, Right and the Angles....

    Example... Paper clips... Left 3 Middle 4 Right 4 Each weighing 1g
    Angles... from the middle point measured from the horizon line..
    Left of center 68deg. Right of center 44deg.


    This is where I am stuck.... I am lost where to go from here.... I know to be in equilibrium I have to come up with 0 but between here and there... I am lost.. I do know I have to use sin and cos but I am lost as to my placement of numbers.. Thank you in advance..

    Here is the set up...

    my example is
    Left 3 clips totaling 3g
    Middle 4 clips totaling 4g
    Right 4 clips totaling 4g

    left angle 112deg and the right angle 44deg..

    hope this makes more sense...
