It is known that the only solution of the mathematical problem has a physical sense i.e. adequate to the mechanical system behavior being investigates, that rather well coincides with the experimental results. The article deals with the analysis of the two ways of conducting experiments corresponding to the investigation of the mechanical system behavior in static. The behavior of a rigid rod pivot-and-spring fixed on the one end and by a loaded concentrated force on the other is considered as an example.
