Statics and Mechanics question, for Engg 205 at U Calgary.

  1. Sep 20, 2008 #1
    1. The problem statement, all variables and given/known data

    The 64-m-tall tower is supported by three cables that exert forces Fab,Fac,Fad and on it. The magnitude of each force is 2.52 kN. Express the total force exerted on the tower by the three cables in terms of components.


    2. Relevant equations

    3. The attempt at a solution

    I've tried to split them into their components so that I take every triangle and try to find the direction cosines and times that by the total magnitute to find the x, y and z magnitudes but I don't think thats right.
