    Why does buckling occur in columns? Quora

    The picture above describes the buckling load in various cases, but what is effective length. Well, in simple works effective length is the length of the column between points of zero moments. In case 1, it is pinned support so the distance between point of zero moments will definitely be L.

  • What is the difference between crushing and buckling

    What is the difference between crushing and buckling

    Buckling, as already explained in several answers is a geometric failure occurring in slender members. Too much deformation at a low level of stress. Slenderness is ratio of length to radius of gyration. Mostly Crushing (by theory) is supposed to occur beyond the material strength.
