Dynamics of Machinery is a comprehensive textbook authored by Mr. J. Ekantha Moorthy, Mr. P. Karthick, Dr. M. Rajesh, Dr. A. John Presin Kumar, and Dr. P. Loganathan, published by Quill Tech Publications. Designed for students, educators, and professionals in mechanical engineering, the book bridges theoretical principles with practical applications, offering detailed insights into the behavior of mechanical systems. It covers fundamental topics such as force analysis, balancing, free and forced vibrations, mechanisms for control, and flywheel dynamics. Beginning with core concepts like kinematics, inertia forces, and torque, the book progresses to advanced topics, including vibration analysis, dynamic modeling, balancing of rotating and reciprocating masses, and energy storage mechanisms using flywheels. Special emphasis is placed on real-world applications, such as dynamic force analysis in reciprocating engines, gyroscopic effects in naval ships and airplanes, and the use of flywheels in industrial machines like punching presses. Each concept is enriched with clear diagrams, mathematical derivations, solved problems, and practical examples. The text also delves into vibration isolation, damping, torsional vibrations, and control mechanisms like governors and gyroscopes, making it a valuable resource for understanding modern mechanical systems. With 276 pages of meticulously organized content, the book aims to enhance problem-solving skills, encourage innovative thinking, and equip readers with tools to design and analyze complex machinery. This first edition, released in December 2024, is priced at ₹850 and includes acknowledgments to the authors’ families and colleagues for their support. Ideal for undergraduate and graduate students, as well as professionals in industries like robotics, automotive systems, and manufacturing, this book combines foundational knowledge with contemporary approaches, ensuring relevance in an era of rapid technological progress.
