Vibration is a mechanical phenomenon that is characterized by oscillations around the equilibrium point. Such oscillations can be periodic or random. Vibrating structures cause sound or pressure waves. Free, forced and damped vibrations are the different types of vibrations. The study of sound and vibration, as well as the design, analysis and control of sound, is undertaken by the field of acoustical engineering. Vibroscopes are devices that are used to trace or record vibrations. The analysis of vibrations is used in the industrial sector to detect faults in equipment and reduce their downtime. It also helps in minimizing maintenance costs. The objective of this book is to give a general view of the different areas of vibrations and their applications. It brings forth some of the most innovative concepts and elucidates the unexplored aspects of this field. As this field is emerging at a fast pace, this book will help the readers to better understand the concepts of vibrations and their engineering.
