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

    The problem requires to determine which of the 2 bars has zero axial forces without any computation.

    2. Relevant equations

    3. The attempt at a solution
    I cant tell which bar has zero axial forces.

    I'm not sure what you mean by, "which of the two bars." There appears to be 25 sections. Is it, "which two bars?" Or is there really only one section? If it's only one section, then look at how you would normally start solving the problem (if you were using equations) and notice where there would only be a force in one direction.
