Tension in a system

  1. Sep 21, 2015 #1
    1. The problem statement, all variables and given/known data
    I was asked to find the tension in CD in this question . The ans given is 4.22kN.
    my working is arc tan (surd 13)/12, tetha = 16.7 degree
    CD cos (16.7) = 20kN
    CD= 21kN.
    p/s: i have used pythagora's theorem to fe the surd 13
    2. Relevant equations

    3. The attempt at a solution

    I don't think there can be tension in member CD.

    The diagram is very unclear. I'm not sure what the various distances refer to, or where the A and B points are in space. Is there a verbal description that goes with it?

    actually i'm asked to find tension in CD, AD , and BD. I've found Cd only . I have no idea at all for AD and BD

    the book stated ' determine the load in each member of the frame shown in Figure .'

    Well, I cannot interpret the diagram. If it is clear to you, please explain your interpretation ( provide co-ordinates for each of the points).
