Preface
During last three decades the subject “Vibrations and Dynamics of Structural and
Mechanical Systems” has undergone significant development. There has been an urge
and urgency of designing present day modern and complex structures and systems
in their proper perspective, a task which could not be conceived even three decades
back, This has been possible due to the advent of the electronic digital computer.
With the exception of the self weight of the structures, strictly speaking, no other
load can be treated as static load. In order to truly analyse these systems, a knowledge
of treatment the dynamic load is of paramount importance.
The existing book on the subject mainly deal with one of the following aspects:
1. Vibrations of Mechanical Systems.
2. Structural Dynamics.
Though basic principles and solution techniques are same for both the above
topics, they primarily differ in their application areas. The main objective of the book
is to present these aspects in a unified and integrated manner. The chapters have been
arranged in such a way that starting from the basics, the reader is acquainted with
more advanced topics in a gradual manner.
The material of the book has been developed while teaching the students of Indian
Institute of Technology, Kharagpur. A similar book was written by the present author
which is no longer available in the market and also it is withdrawn. As such a necessity
has arisen for the publication of the present book.
The author is indebted to a number of persons, without whose help, the preparation
of the manuscript would not have been possible. To name the most important persons
amongst them are—Das, Prabir Sinha, Parimal Kumar Roy, Chinmoy Mukherjee and
Ratna, the wife of the author.
Lastly, the author expresses his sincere thanks to Mr. Sunil Saxena, Jai Raj Kapoor
and Sudipta Ghosh—all of Ane Books, for their help and the excellent cooperation
received.
