Homework Help: Find Vector Equilibrium?

  1. Jan 27, 2015 #1
    1. The problem statement, all variables and given/known data
    Place 0.150kg (including the mass of the hanger) at a position somewhere between 0 degrees and 90 degrees. (I chose 45 degrees for this problem.) Place the second pulley at exactly 180 degrees and the third pulley at exactly 270 degrees. Determine how much mass you must place on the second and third pulleys for the system to be in equilibrium.
    I am really not sure about how to approach this problem, any help would be greatly appreciated. Thank you!

    2. Relevant equations

    3. The attempt at a solution

    Is there a figure that goes along with this problem statement? Put yourself in our place. Do you really think we can figure out what the system looks like from what you've written? We're good, but we're not mind readers.

    Sorry, I still don't follow the description. Maybe someone else can.

    I see three lines. Are these lines pendulums? are these masses connected in any way? Sounds like the problem revolves around a contraption, we just don't know what it is.
