# Computing axis forces of a construction

twoflower
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.

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).

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.
