PREFACE

Giving life to an engineer’s dream for the betterment of society involves Design, Drawing and Safety. With the increasing complexities of economy, as well as the ensuing disruption in IT, besides the stringent safety rules, this inter-disciplinary subject has become challenging to comprehend from exam point of view.

Looking at the nature of Engineering Services Examination (ESE), and the level of questions being asked, the conventional approach of preparing through theory and examples does not serve the purpose. This book attempts to provide logical reasoning through mathematical analysis, gives a clear insight into the concepts, and paints a complete picture in front of your eyes. For students to discover the extent of their learning, practice questions have been provided at the end of this book.

In their endeavour to give students the best, Mr. Bipin Thakur has shared his subject knowledge of Design and Safety, and Mr. Himadri Shekhar (Aahil) that of Drawing in this book in an easy to understand language that gives in a complete clarity of thought. As a result, what students get is their collective wisdom that breaks free the constraints of engineering students in appreciating the General Principles of Design, Drawing and Safety.

As you navigate through this book, a slew of diagrams, flow charts, mind maps and tables, pack a tango that your eyes can relish on. This book is an ESE aspirant’s delight that communicates, connects, and builds upon the exam preparedness right up to the standards of the UPSC.
