The dependence of the critical speed of rotation on the variable radius of a contour circle is determined by means of the small parameter method. Proceeding from the Saint-Venant condition of fluidity, we obtain the characteristic equation for the critical radius of a plastic zone in the first approximation. The values of the critical angular speed of rotation for various parameters of the system are determined numerically.
