In the absence of torque, the tangential stresses in the cross sections of the rod are usually associated with the values of the transverse force and are determined by means of D.I. Zhuravsky’s well-known formula. However, this is not always correct. In beams with variable cross-section and even in those with constant rectangular section loaded with longitudinal load the stresses found by Zhuravsky’s formula can differ significantly from the actual ones. The tangential stresses in cross sections with a discontinuous changes in width are not always determined correctly. The article reveals the causes for wrong solutions. Zhuravsky’s formula as well as the type of its record and the scope of applicability is analysed in it. It considers a common method for determining the tangential stresses from all possible loads in beams with a given cross-section whose dimensions can vary along the axis of the rod. The stresses found by this method coincide with sufficient accuracy with the solutions performed by the methods of the theory of elasticity and the numerical ones in complex cases. |
