    Discrete Model for Buckling Mode Shapes of a Clamped-Free Column

    the buckling shape for clamped-free column is v(x)=1-cos(n*pi/2*L), n=1,3,5 ... how could i use the discrete model to get the buckling mode shape matrix? for example 3x3 matrix form a stiffness matrix and solve the eigenvalue problem? L=1;E=1;I=1 l=L/3 % 3-element beam...

    A vibrating column with a critical load exerted on it

    I was wondering the critical load vary as a result of forced vibration? Intuitionally, I thought the critical load reduced. But how to show it analytically, Any idea?
