Euler's Buckling Load

  1. Jul 22, 2009 #1
    1. The problem statement, all variables and given/known data

    A piece of spaghetti 5 cm in length and 2mm in diameter has a weight of 0.2 gms. It will break under tension at a load of 5 kg (force). And its Euler buckling load is 500 gms (force). What length of the spaghetti could be suspended vertically from one end before it broke under its own weight?

    What if the diameter were 4mm?


    2. Relevant equations

    EI(d2y / dx2) + Py = 0.

    Have you made an attempt at a solution? Note that buckling criteria applies to members subject to compressive stresses. Is the hanging spaghetti subject to tension forces and/or compression forces?
