Homework Help: Computing axis forces of a construction

  1. May 3, 2007 #1
    Hi all, I'm trying to compute the axis forces in the construction I put to attachment. I already have computed the R forces, but I don't know where should I start computing the axis forces from, from which point.

    Could please someone give me some advice?

    Thank you very much,
    best regards.

    You could start by applying the node method at the top.

    Thank you very much, Cyclovenom!

    However, I'm still not able to finish the exercise. Could you please advise me which of the bars are zero-force? (I mean they have a zero axis force).

    Thank you in advance.

    Which members without doing the problem you think are zero force members?

    Where are you stuck? maybe you can show your work and we can see why are you stuck.
