We study a plane problem of the theory of elasticity for a circular disk containing a randomly located arc-shaped crack under the action of a rotating load. The problem is reduced to a singular integral equation, which is solved numerically by the method of mechanical quadratures. We determine the numerical values of the stress intensity factors and angles of initial propagation of the crack depending on its location and geometric parameters (curvature and length).
