The article presents further development of the theorem proposed by the author: "Some solutions of the elementary theory of bending coincide with solutions of the elasticity theory for special values of the Poisson's ratio". Herewith, firstly, a cross section in the form of a square rhombus of independent interest is considered, and, secondly, a new group of sections covered by the theorem is indicated.
