    3. The attempt at a solution

    I was attempting to solve this exercise, but since I have no answers, I have no way of knowing if it's correct.

    Any help Is more than appreciated

    You did a superior job with this and your work is well presented.. the lowest value of P is the answer. Excellent work!

    By the way Elongations (z - from left to right within each segment)
    [itex]w_{{1}}=4\,{\frac {Pz}{E\pi \,{{\it Diam}}^{2}}}[/itex]

    [itex]w_{{2}}=4\,{\frac {P \left( z{{\it Diam}}^{2}+a{{\it diam}}^{2}
    \right) }{{{\it Diam}}^{2}E\pi \,{{\it diam}}^{2}}}[/itex]
