                    be neglected. Therefore, if  external moments are absent one obtains


                                                                                         (J. 19)

                    where I,  is the moment of inertia of the pipe about the z-axis.
                      Substituting (J.18), (J.19), (J. 14) and (J.l) into equations (J.15), the equations of motion
                    for the pipe, i.e. equations (6.16), may be obtained.
