Random Vibrations of Systems with Finite Number of Degrees of Freedom,.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 . about the central axis that is perpendicular to the plane of the drawing.

Non-Stationary Random Functions (Processes),In engineering practice, we have to examine random quantities depending on continuously varying nonrandom arguments, such as the time . and the coordinates .. This kind of random quantities is referred to as random functions.
