A different statics question

  1. Sep 30, 2007 #1
    1. The problem statement, all variables and given/known data


    2. Relevant equations


    3. The attempt at a solution


    i assumed that there is a 90 degree angle at point B but i'm not sure if that's correct, i'm pretty stumped with this question...i just need a few pointers.

    The tension in the cable acts in a direction along its length. You can calculate the angle that it makes at B from the given dimensions using trig. It is not 90 degrees. Once you determine the angle, get the x and y components from your relevant equations, and watch the direction, left or right, up or down.
