This study is concerned with the determination of the eigenvalues and "eigenfunctions" of an axially vibrating, viscously damped elastic rod, carrying a tip mass and consisting of two parts having different physical parameters. The eigencharacteristics of the rod are determined via an original application of the separation of the variables method. The reliability of the method used is justified on a sample system, the eigenvalues of which are also calculated numerically by a finite element model.
