Review article

The differential bending equation of the rod, written in terms of bending moment and taking into account compression or tension by the force of arbitrary degree of smallness, allows solving simple statically indeterminate problems without calculating the deflections. If there is no force, such possibility disappears. The proposed article examines this unusual effect. The article also examines the bending problem of the rod under condition of large displacements. Direct integration of differential bending equations is used.
