A system consisting of a guide along which a heavy mass moves is considered. A guide is considered to be a homogeneous beam lying on the elastic base of the Pasternak model. The features of bending wave generation by a moving load are studied. Based on the general solution of the problem, an expression is obtained for the pressure of the waves (the forces of resistance to motion).
