✦ Synopsis


If one considers the set of vertical and horizontal loads applied to the column with constant inertia, the classical homogeneous Euler differential equation of the third-order expressing the behavior of the column under its own weight uniformly distributed along the vertical axis is transformed into a non-homogeneous equation by the concept offictitious length.

A new operator attached to Bessel junctions is introduced, and the general solution to the nonhomogeneous equation is obtained, leading to a formula expressing the critical load of the bar. Newformulae are also proposedfor the critical load of the bar under its own weight acting alone, and under different support conditions.
