The areas of dynamic stability for mechanical elements with longitudinal vibra-

In trusses under the influence of variable loads, vibrations occur periodically in

different elements, characterized by fluctuations in speed and stress. Under certain conditions, due to wave motions in the rods, the shape of the oscillations may change, i.e., lost stability of motion. At this instant, the destruction of the carrier element will occur. The proposed chapter considers the conditions for the
