BASIC MECHANICAL ENGINEERING

Welcome to the magical world of Basic Mechanical Engineering. Mechanical Engineering is instrumental in changing the lives of mankind in all spheres of life. This book is an introduction to the fundamental principles of mechanical engineering. It is intended for first year undergraduate engineering students who are new to the field, as well as for anyone who wants to learn more about how mechanical engineering works.

We have worked in industry and later on have been teaching mechanical engineering for over many years, and we have seen first hand the challenges that students face when they are first learning the material. This book is designed to make the learning process easier and more enjoyable. We have tried to present the material in a clear and concise way, and we have included many examples and exercises to help readers understand the concepts.

This book is divided into six chapters parts:

Chapter I: Fundamentals of Thermodynamics
Chapter II: Introduction to IC Engines, Air Standard Cycles
Chapter III: Introduction to Refrigeration and Air Conditioning
Chapter IV: Energy Sources and Power Plants
Chapter V: Mechanical Power Transmission and Energy Conversion Devises
Chapter VI: Manufacturing Processes

Chapter I covers the basics of thermodynamics viz thermodynamic systems, state, process, cycle, Heat & Work and finally with first and second law of thermodynamics

Chapter II deals with internal combustion engines viz. SI and CI engines, two stroke and four stroke engines, air standard cycles like Carnot cycle, Joule cycle, Otto and Diesel cycles.

Chapter Part III covers refrigeration and air conditioning. including refrigerants, vapour compression cycle, vapour absorption cycle, solar refrigeration, window air conditioners, psychometric properties of air and applications of refrigeration

Chapter IV deals with energy sources and power plants where we discuss renewable and non renewable energy , solar flat plate collector, Solar PV cells, Wind energy , Bio-gas, Bio-diesel, Hydel and steam power plants.

Chapter V deals with types of belts and belt drives, chain drive, types of gears and gear drives, centrifugal pump, reciprocating compressor, Pelton wheel turbine

Chapter VI deals with manufacturing process such as casing, lathe, milling, drilling and finally metal joining processes ie soldering, brazing and welding

We hope that you find this book to be a valuable resource as you learn about basic mechanical engineering. If you have any questions or feedback, please feel free to contact me.
