Help with tensions

  1. Oct 13, 2003 #1
    I have having difficulty with tensions. Can someone give a good explanation of how they work and what are some rules to solve the problems I have for homework.

    Here is one example of a problem:

    A picture hangs on the wall suspended by two strings as seen in the figure 6-20(see below for a written explanation). The tension in string one is 1.7N. (a) is the tension in string 2 greater than, less than or equal to 1.7N (explain) (b)verify your answer by calculating the tension on in string 2 (c) what is the weight of the picture?

    In the example there is a pictrue hanging in the middle of two strings, one string string one in 65degrees above the -X axis and string 2 is 32degrees above the X axis.

    Here is what I have done:

    T1x = 1.7(-cos115degrees)
    T1y = 1.7(sin115 degrees)
    and that is it...HELP!!
