Three masses suspended by cables: Force Question: HELP PLEASE!

  1. Oct 15, 2011 #1
    1. The problem statement, all variables and given/known data

    Three masses are suspended by cables as shown. Find the tension in each cable.

    Picture:

    2. Relevant equations

    W=mg

    3. The attempt at a solution

    T1: W= mg
    = 15 kg x (9.8 m/s^2)
    = 147 N

    T2: W= mg
    = 11kg x (9.8m/s^2)
    = 107.8 N

    T3: W=mg
    =5kg x (9.8m/s^2)
    = 49 N


    Is this right? I'm pretty confident in it, but the lecture I watched before attempting this among several other problems wasn't very helpful. Thank you!

    Bump? This homework is due in less than 2 hours and I'm stressing that I'm going to get it wrong.

    Yes, that looks correct.
