Homework Help: Tension and Wires

  1. Nov 20, 2014 #1
    1. The problem statement, all variables and given/known data
    Three pictures of equal weight (20 N) are hung by wires in three different orientations. In which orientation are the wires least likely to break? Orientation A: 15 degree with horizontal,Orientation B: 45 degree angle with horizontal, Orientation C: 60 angle with horizontal?

    2. Relevant equations
    No relevant equations.

    3. The attempt at a solution
    I was able to answer the question correctly (orientation C), but I need more information as to why that is correct. I already said that the distance between the two wires should be smaller because it would mean less gravity and therefore less tension. What part am I missing?

    What does less gravity mean? Don't all the pictures have the same weight?

    Hint: think about why a wire is going to break in the first place.
