Response of One-Degree-of-Freedom System to Harmonic Loadingparts of such machinery. Furthermore, even in those cases when the excitation is not a harmonic function, the response of the structure may be obtained using the ., as the superposition of individual responses to the harmonic components of external excitation. This approach will be dealt with in Chap. . as a special topic.

Damped Single Degree-of-Freedom Systemplex and is not completely understood at this time. In order to account for these dissipative forces in the analysis of dynamic systems, it is necessary to make some assumptions about these forces, on the basis of experience.

Damped Single Degree-of-Freedom Systemith a constant amplitude at its natural frequency. However, experience shows that it is not possible to have a device that vibrates under these ideal conditions. Forces designated as frictional or damping forces are always present in any physical system undergoing motion. These forces dissipate ener

Response of One-Degree-of-Freedom System to Harmonic Loadingted to forces or displacements whose magnitudes may be represented by a sine or cosine function of time. This type of excitation results in one of the most important motions in the study of mechanical vibrations as well as in applications to structural dynamics. Structures are very often subjected t
