Welcome to the world of mechanical engineering! This book, "Elements of Mechanical Engineering," is designed to be your comprehensive guide through the fundamental principles and concepts that form the bedrock of this exciting field. This book is primarily intended for students pursuing courses in mechanical engineering at various levels, but it is also a valuable resource for the students of other disciplines also who wish to acquire basic knowledge on mechanical engineering. We have strived to make the content accessible to readers with varying levels of prior knowledge in the field.

In writing this book, we have drawn from our collective experience as educators, researchers, and practitioners in mechanical engineering. Our aim is to present the material in a clear and engaging manner, with an emphasis on fostering a deep understanding of the core concepts. We encourage active learning through examples, exercises, and thought-provoking questions. Dr. M. Maruthi Rao contributed for the topics like Thermal engineering and Mechanical power transmission. Dr. S. Ravi babu contributed for the topics like Introduction to mechanical engineering, Role of mechanical engineering in various sectors, Manufacturing processes and power plants. Mr. V. Pavan Kumar contributed for the topics like Engineering materials, Introduction to robotics.
