A First Course in Engineering Drawing

The primary objective of this book is to provide an easy approach to the basic principles of Engineering Drawing, which is one of the core subjects for undergraduate students in all branches of engineering. Further, it offers comprehensive coverage of topics required for a first course in this subject, based on the author's years of experience in teaching this subject. Emphasis is placed on the precise and logical presentation of the concepts and principles that are essential to understanding the subject. The methods presented help students to grasp the fundamentals more easily. In addition, the book highlights essential problem-solving strategies and features both solved examples and multiple-choice questions to test their comprehension.

Author Biography: K. Rathnam obtained his Bachelor's degree in Mechanical Engineering from the Government College of Technology, Coimbatore, under Madras University, Chennai in 1968 and his M. Tech degree in Mechanical Engineering from the Indian Institute of Technology, Kanpur in 1972. He has thirty-three years of teaching experience at Annamalai University, Tamil Nadu, India, where he has offered courses on e.g. Engineering Drawing, Thermodynamics, and Fluid Mechanics at the undergraduate level. He has published two papers in the Journal of Sound and Vibration and two papers in Acta Acustica in the areas of acoustic wave propagation in tubes. He is the author of one textbook, Thermodynamics, published in 2013 by Pearson, Chennai/Noida (ISBN 9788131795507). His specialty is Engineering Drawing, an area he has taught in for more than thirty years.
