Homework Help: A Loudspeaker is suspended by Cables

  1. Sep 18, 2008 #1

    1. The problem statement, all variables and given/known data

    A 18 kg loudspeaker is suspended 1.6 m below the ceiling by two 3.0 m long cables that angle outward at equal angles. What is the tension in the cables?

    2. Relevant equations

    F= ma

    3. The attempt at a solution

    I believe that I have the drawing correct, but I've never learned how to go from here. I can't seem to find enough numbers (even with the given values) to actually complete any sort of equation. I do know that the tension in both the cables is the same. So:

    F(tension)= a(18)

    How do I move from here if I do not have acceleration and it is not a given?

    Thank you,
