Homework Help: Statics: Multi force members

  1. Apr 24, 2010 #1
    I am studying statics and more precisely multi force members. I understand the process about solving how to find reactions and forces in x and y directions. However, I have a great tendency to confuse it when if comes to figuring out angles to write equilibrium equations.

    Any help for me to clear out how to find angles on the attached figure?



    Thank you.
    1. The problem statement, all variables and given/known data



    2. Relevant equations



    3. The attempt at a solution

    Re: Frames-statics

    A good idea would be to start out with trigonometric identities for right triangles. :)

    sinx=opposite/hyppotenusse
    cosx=adjacent/hypotenuse
    tanx=opposite/adjacent

    that's all I need to find the angles. I am not sure why you have taken it too far.However, I appreciate your answer.


    Thank you
