Homework Help: Magnitude and direction question!

  1. Nov 9, 2004 #1
    "A sign weighting 495N is supported as shown in the attachment. Determine the magnitudes and directions of the forces exerted by the chain and by the bracket. assume that the horizontal rod cannot support vertical forces."

    How do I set up this question? Do I use the law of Sins? Cos?

    I really hate learning from the book, and since the book didn't show an example of this type of problem I dont really know where to start. Not asking for the solution, just a little kick start help. Thanks
