The stability and dynamics of elastic and viscoelastic models of column and inverted double pendulum, subject to a generalized follower force is considered in the paper. The analysis has confirmed the existence of the fixed point in frequency domain, revealing in a value of loading for which the frequency of natural vibration occurs independent of variety of the system parameters. The detailed analysis of modal forms reveals, that at the fixed point, the structural eigenmode changes, the first eigenmode varies into the second one. Finally the critical force appears with the second eigenmode which, however corresponds to the fundamental eigenfrequency. The higher eigenmode relates to the shorter buckle lenght, what reveals in multiply higher values of the critical load, comparing it with the Euler critical load.
