Response Spectra-of-freedom system, the maximum displacement of the mass . relative to the displacement at the support. Thus, to determine the response from an available spectral chart, for a specified excitation, we need only to know the natural frequency of the system.

Response to General Dynamic Loadingom system to a general type of force. We shall see that the response can be obtained in terms of an integral which for some simple load functions can be evaluated analytically. For the general case, however, it will be necessary to resort to a numerical integration procedure.

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 the external excitation. This approach will be dealt with in Chapter 5.
