2 Dimensional Tension Force Homework Help

  1. Nov 29, 2012 #1
    1. The problem statement, all variables and given/known data
    A sign is suspended from two strings as shown. Determine the wheight of the sign.
    Left string: Fτ=25 Newtons; ∅=40 degrees
    Right String:Fτ=25 Newtons; ∅=40 degrees

    2. Relevant equations
    i no that the mass is at equilibrium, so the tension forces are equal and opposite.


    3. The attempt at a solution
    I first used sin to help me and I got 16.1 Newtons on both sides, but I don't know where to go from there.

    In the free body diagram of the sign, what do you get for the balance of vertical forces?
