Overview with Some Definitions and Mathematics,r-Lagrange approach in Chap. 3. I also discuss scaling, the art of rendering the equations of mechanical system dimensionless, and review the connection between trigonometric functions and the complex exponential, essential for solving the ordinary differential equations governing mechanical systems.

One Degree of Freedom Systems,amped natural frequency, damping ratio, and critically damped, underdamped, and overdamped systems. I illustrate these ideas with simple models of several practical examples: accelerometers, seismometers, air bag sensors, and rotational imbalance. I give a quick preview of block diagrams, state space, and simulation.

Modal Analysis,cuss the measurement of vibrations and introduce Fourier series and power spectra as analytic tools for vibration measurement. I discuss the transversely vibrating string and longitudinal and transverse vibrations of a simple beam as examples of the vibration of continuous mechanical systems.

Vibration Measurement,rements using power spectra, introducing many aspects of Fourier series in the process. I discuss sampling problems, including Nyquist phenomena — the Nyquist frequency and aliasing — with artificial examples to illustrate aliasing in action.
