Mechanical engineering is an established and prominent field of engineering that is concerned primarily with designing, manufacturing and maintaining various machines, equipment and mechanical systems. Thermodynamics plays a significant role in conceptualizing, designing and manufacturing of different machines and mechanical structures. The principles of heat exchange, relation between work and energy output, temperature measurement are crucial to mechanics and engineering. This book encompasses different principles, concepts, tools and techniques involved in mechanical engineering and the role of thermodynamics in this field. Students, researchers and engineers will find this book a wonderful reference source.
