Nayfeh, Ali Hasan, and Dean T. The method of the direct separation of motions is even easier to use than the multiple scales. But sensibly organized and controlled vibrations may be pleasant think of all kinds of music or vitally important heartbeat. This approach is consequently applied both to systems with strong linear damping and to systems with inelastic collisions.

These discussions induced the author to start his activities on the analysis of discontinuous systems and encouraged him to try to modify the averaging method in the appropriate manner. But at some sufficiently large level the beam will simply break. The simplest experiment illustrating this statement is an attempt to bend a wooden beam.

The main idea here is to separate the dissipative subsystem, which moves in many important cases as a slave of the almost conservative subsystem at least in the first order approximation. Another example is based on the crank mechanism usual in all kinds of machines Fig. Thus approximate analytic methods are both necessary and useful. The relevant theorems are formulated and explained qualitatively.
