In this paper, the buckling strength of a beam on an elastic foundation supported within its span by equally distant elastic supports is treated. A formula is derived for the coefficient of rigidity of these elastic supports that ensure a given value of the Euler force. It has been proved that a specific value of the coefficient of rigidity exists (it is called the critical coefficient of rigidity), beyond which its further increase does not increase the Euler force. Also, assuming the stiffness of the elastic foundation equal to zero, a formula is derived for the coefficient of rigidity of the elastic supports for a beam that does not lie on an elastic foundation. Several examples are given for calculation of the required and critical coefficient of rigidity of the elastic supports.
