The phenomenon of buckling of bar under tensile load is revealed in many cases of loading and found consideration in some structures and mechanisms. The tensile buckling load depends on dimensions and material of the bar as well as on flexibility of connections at its ends. This paper describes the dynamic method for determining the tensile buckling load of bar on example of bar subjected to tensile load by a force directed towards the pole. Connection at the lateral non-movable end may vary from the hinge to the restrained including semi-rigid. The theoretical basis of the method is the dependence of the bar lateral stiffness on tensile load. The lateral stiffness is determined for various values of the tensile load based on free vibrations frequencies of the bar with mass at its tip as well as its own generalized mass. The tension critical load is obtained by extrapolation of the dependency between the stiffness and tensile load up to its zero value. The accuracy of the method is verified by comparing the experimental results and corresponding analytical values. Experimental measurement of critical tensile load of the stretched bar loaded by force directed to a pole is performed for the first time.
