As a rule, the presentation of a real mechanical system as a system with one degree of freedom is approximate. For example, the system shown in Fig. 6.1 usually considered that with one degree of freedom is a system with two degrees of freedom (if we neglect the inertia of the rod and examine the motion of the mass only in the plane of the drawing), as the real lumped mass has a non-zero moment of inertia J0 about the central axis that is perpendicular to the plane of the drawing.
