Strain gauges in stress-strain state calculation of a non-rigid rod under noncentral tensile

In practice, joint work on bending and tension (compression) is quite common. Such kind of deformation, called eccentric tension (compression), can occur due to axial forces applied with eccentricity. Examples of this type of deformation are a crutch bolt, a clutch spring, a welded joint, etc. To determine the hardness and rigidity of such elements, it is necessary to study the stress-strain state, which was done in this work using various methods using the example of a non-rigid rod. One of these methods was an experimental research using the SoM-1 installation. The measuring of deformations was carried out using strain gauges. Modeling of a flexible rod and strain gauges was also carried out using the finite element method. The third option for solving this problem was the analytical method using strength of materials formulas. A comparative analysis of the results obtained by the above methods was carried out.
