                          wear, vibration, noise or heat generation [6]. Furthermore, the greater the deflection,
                          either bending or torsional, the lower the corresponding critical speed. Therefore, the
                          rigidity or stiffness of shafts, both in bending and torsion, must be analysed. The deflec-
                          tion must be kept within specified limits to ensure satisfactory operation of mounted
                          elements.
