Preface
Theory of machines is an important subject not only to mechanical engineering discipline, but also to other engineering disciplines. All products whether they are mechanical, electrical, civil, computers or electronics, are designed, manufactured and maintained by mechanicals only. This is one of the interesting and useful subject which deals with the mechanisms and machines. The book covers both kinematics and dynamics of machines. The book will be useful not only to degree level students of mechanical engineering but also to those preparing for AMIE and various other competitive examinations. Chapter 1 introduces the concepts of mechanisms and machines. In Chapter 2 various mechanisms consisting of lower pairs are discussed. Chapter 3 deals with the analysis of their motions such as velocities and accelerations of various mechanisms using di erent methods. Chapter 4 deals with the study of kinetics, the time-varying forces in machines such as torque and power. Chapter 5 gives turning moment diagram and design of ywheels. Chapter 6 gives about friction and its e ect on mechanical e ciency. The friction e ects on bearings and its uses in power transmission. In Chapter 7, types of governors for speed regulation are presented. Chapter 8 deals with transmission of power using belts, ropes and chains. Chapter 9 deals with gyroscopic e ects on the vehicles such as two wheelers, four wheelers, aeroplanes and ship. Chapter 10 gives about di erent types of cams and their design. Chapter 11 deals with gears and their types. Chapter 12 gives the application of gears used for transmission of power. Chapter 13 and Chapter 14 deal with balancing of rotating masses and reciprocating masses. Chapter 15 and Chapter 16 are on the study of longitudinal, transverse and torsional vibrations. Generally in many books, several examples will be given but in this book a few common examples are shown for di erent methods. This will enable students or new faculty to understand the relative merits and demerits of the methods. This will help them in choosing the right method for the given problem and the time it requires. For example, in the velocity and accelerations, whether to use instantaneous centre method or relative velocity method and in the governors, whether to use analytical or graphical method, etc. are given so that the students will not try in the examination time or new faculty in the classrooms while teaching. Another highlight of this book is unlike other books where di erent problems are shown for di erent parameters whereas in this book, the same problem has been shown by changing each time one parameter. This will give a clear idea to students the e ect of that particular parameter. For example in cams, the e ect of follower, motion, whether it is o set or radial cam on its pro le. In governors, Porter or Proell, unequal or equal arms, pivoted on the spindle or away from the spindle, etc. Students should not attempt by trial and error way especially in the examinations time.

Preface
The author has written this book by his forty years of teaching experience. This book will help not only to students but also to new faculty members for preparing well in all the above aspects with con dence. The international System of Units SI has been adopted throughout the book. The author thanks all those who in uenced him in writing this book. B.V.R.
