Tension in strings

  1. Jan 1, 2012 #1
    1. The problem statement, all variables and given/known data

    A mass of 5.00 kg hangs attached to three strings as shown in the figure (see image below). Find the tension in each string. Hint: Consider the equilibrium of the point where the strings join.


    2. Relevant equations

    W=mg


    3. The attempt at a solution

    Well finding the tension in string 3 (T3) was relatively easy:

    w=mg
    mass of the block = 5.00 kg
    g = 10 ms-2
    w = 5.00 x 10 = 50 N

    It is the other two (T1 and T2) i'm not sure. In fact I'm at lost with what I learned in class and applying. I noticed the problem states a hint (equilibrium where strings join) but I'm not seeing how this information can be used.

    Thank you Sammy. I noticed what I had done wrong, I ignored to look at the vectorial components. After that, the rest unfolded easily. Thanks again :)
