In the work the dynamic system of laboratory model of the truck crane consisted of a telescopic boom and a hydraulic cylinder and a rotary platform is considered. The result in the form of frequency curves for changing both the load and the geometry of the system have been presented.
The problem of the dynamic stability of columns under generalised load as well as loaded by a followerforce passing, through a fixed point bas been considered. Geometrical and physical properties of columns have been assumed in such a way that the columns are of the divergence pseudoflutter type. The change of the natural frequency versus the load as well as the influence of the varied part of the...
