Mechanical engineering is a branch of engineering, which is involved in the manufacture, design, maintenance and analysis of mechanical systems, by combining the principles of mathematics, engineering physics and materials science. The field of mechanical engineering requires knowledge of core areas such as thermodynamics, structural analysis, mechanics, materials science, dynamics and electricity. This branch of engineering aids in designing and analyzing heating and cooling systems, medical devices, transport systems, weapons, robotics, manufacturing plants, aircraft, industrial equipment and machinery and watercraft, using tools such as product lifecycle management, computer-aided design (CAD) and computer-aided manufacturing (CAM). It is concerned with the operation, design and manufacturing of machinery and it overlaps with metallurgical engineering, aerospace engineering, civil engineering, manufacturing engineering, industrial engineering and chemical engineering in varying amounts. This book elucidates the concepts and innovative models around prospective developments with respect to mechanical engineering. It will serve as a valuable source of reference for graduate and post graduate students. This book traces the progress of this field and highlights some of its key concepts and applications.
