Influence of a transversal load on the stability of a rod compressed by a longitudinal force

The work is devoted to the study of the effect of normal load on the stability of a rod compressed by a longitudinal force. Two types of boundary conditions are considered: the boundary conditions of rigid sealing and the conditions of hinge support. It is noted that in the case of the boundary conditions of the hinge bearing, the shape of the elastic line of the rod qualitatively depends on the magnitude of the longitudinal force.
