About the BookAbout the AuthorTable of Contents

The main objective of a basic course in Engineering Mechanics is to enable the student to understand and analyse the actions and reactions of bodies at rest or in motion. For this a thorough understanding of the underlying physics is necessary, along with the ability to solve problems in a simple and logical manner. The contents of this book have been developed keeping this in mind. A good number of multiple-choice questions, short-answer questions, descriptive questions and numerical problems have been included in each chapter along with their solutions so that students are exposed to a variety of situations that will test their understanding of the subject both at the conceptual and analytical levels. The book, apart from catering to the needs of undergraduate engineering students, will also be a ready reference for those appearing for various competitive examinations in India.
