The undergraduate-level textbook, Basic of Mechanical Engineering, is intended for students pursuing various engineering disciplines, including Electrical Engineering, Civil Engineering, Food Technology, and Electronics. The book comprises 17 chapters that focus on the fundamental concepts of Mechanical Engineering. Moreover, the book aims to cover not only the theoretical aspects of mechanical engineering but also its practical applications.

The book also seeks to address a broad range of mechanical engineering subjects, such as thermal science, power generation, internal combustion engines, hydraulic machinery, refrigeration, refrigerants, simple lifting machines, power transmission methods, and strength of materials. Additionally, the book includes an energy and exergy analysis of the milk processing industry. While the book is designed to adhere to the syllabus, it also provides supplementary information and resources.

The concepts of thermodynamics, internal combustion engines, refrigeration, and solid mechanics have wide-ranging industrial applications. Therefore, this book is beneficial for all engineering graduates to acquire foundational knowledge in mechanical engineering quickly.
