Bacteriathe speed ω, are of the form . External h. and internal h. damping coefficients, reduced to the reference unit mass (Aρ). of the shaft are . c. and c. are equivalent viscous coefficients of external and internal damping and Aρ and EI are respectively mass of unit length and stiffness of the shaft, both variable along the axial coordinate z.
