Governing Equation of Motions,rtual work principle (D’Alembert’s principle), Hamilton’s principles, and Lagrange’s equations. We shall also see the important role of energy in the study of dynamic analysis. It is noted that each of the formulations basically represents the same dynamic equilibrium but in a unique form of express

Solving Eigenproblem for Continuous Systems: Rayleigh Energy Method, form (exact) solutions in this case are not available. Therefore, approximate solutions have to be sought. Many methods are available for approximating the eigenvalues. All of these methods are based on a discretization of continuous systems, i.e., replacing the system by an equivalent discretized

Time Domain to Frequency Domain: Spectrum Analysis, colors from red to violet in about 1700. This indicates that any light comprises numerous components of light of various colors (wave lengths). The earliest function most closely resembling the spectral density function was developed by Arthur Schuster, who investigated the presence of periodicitie

Vibration of Multi-Degrees-of-Freedom Systems,erent from the others but also coupled. The number of degrees-of-freedom is equal to the number of independent coordinates necessary and sufficient to describe complete motions of the system. Therefore, the system will have the same number of eigenfrequencies and mode shapes as degrees-of-freedom. T
