Geared toward advanced undergraduate and graduate students in engineering, this concise textbook discusses vibration problems, dealing with systems of one and more than one degree of freedom. Numerous examples and problems assist students in mastering the material and demonstrate the applicability of the methods of analysis used in the text. Starting with an overview of the fundamentals, the treatment examines undamped vibrations of single-degree-of-freedom systems, vibrations of single-degree-of-freedom systems with viscous damping, systems of one degree of freedom with nonviscous damping, and undamped vibrations of systems with more than one degree of freedom. Additional topics include application of generalized coordinates, damped vibrations of systems with more than one degree of freedom, and tabular methods for finding natural frequencies. Numerous figures illuminate the text, which concludes with a substantial section of answers to the problems.
