This article is a continuation of a previously published work presenting the results of an experiment conducted on a height-adjustable Vibraсon® SM prop. The results of the experimental studies presented in this paper show that there are considerable elastic deformations in Vibracon props. When screwing the nut and as a result of precompression and final screwing, the initial contact of the parts from the line contact outgrows into the flush contact. As a result, slippage occurs and a hysteresis loop takes place, the area of which depends on the amplitude of the force acting on the prop. The conclusions given in this article are part of the research work (master's thesis) aimed at ensuring proper consideration of the parameters examined and the results obtained in modeling and studying the props.
