e feel satisfied in presenting the new edition of
this popular treatise. The favourable and warm
reception which the previous editions and reprints
of this book have enjoyed all over India and abroad, is a
matter of great satisfaction for us.
The present multicolour edition has been thoroughly
revised and brought up-to-date. Multicolour pictures have
been added to enhance the content value and to give the
students an idea of what he will be dealing in reality, and to
bridge the gap between theory and practice. This book has
already been included in the ‘Suggested Reading’ for the
A.M.I.E. (India) examinations. The mistakes which had
crept in, have been eliminated. We wish to express our
sincere thanks to numerous professors and students, both
at home and abroad, for sending their valuable suggestions
and recommending the book to their students and friends.
We hope, that they will continue to patronise this book in the
future also.
Our grateful thanks are due to the Editorial staff of
S. Chand & Company Ltd., especially to Mr. E.J. Jawahardatham
and Mr. Rupesh Gupta, for their help in conversion of the
book into multicolour edition and Mr. Pradeep Kr. Joshi for
Designing & Layouting of this book.
Any errors, omissions and suggestions, for the improvement
of this volume brought to our notice, will be thankfully
acknowledged and incorporated in the next edition.

e take an opportunity to present this standard treatise
entitled as ‘A TEXTBOOK OF MACHINE DESIGN’
to the students of Degree, Diploma and A.M.I.E.
(India) classes in M.K.S. and S.I. units. The objective of this
book is to present the subject matter in a most concise,
compact, to the point and lucid manner.
While writing the book, we have continuously kept in mind
the examination requirement of the students preparing for
U.P.S.C. (Engg. Services) and A.M.I.E. (India) examinations.
In order to make this volume more useful for them, complete
solutions of their examination papers upto 1977 have also been
included. Every care has been taken to make this treatise as
self-explanatory as possible. The subject matter has been
amply illustrated by incorporating a good number of solved,
unsolved and well graded examples of almost every variety.
Most of these examples are taken from the recent examination
papers of Indian and foreign universities as well as professional
examining bodies, to make the students familiar with the type
of questions, usually, set in their examinations. At the end of
each chapter, a few exercises have been added for the students
to solve them independently. Answers to these problems have
been provided, but it is too much to hope that these are entirely
free from errors. In short, it is earnestly hoped that the book
will earn appreciation of all the teachers and students alike.
Although every care has been taken to check mistakes
and misprints, yet it is difficult to claim perfection. Any errors,
omissions and suggestions for the improvement of this treatise,
brought to our notice, will be thankfully acknowledged and
incorporated in the next edition.
