"The current global state of engineering technologies reveals mainly the development made in the course of 20th century. surprising results and growths have been covered in many respects, but there is also evidence of a growing number of negative by-products — environmental pollution is increasing at higher levels because of mounting industrial activities, malfunctions of large production plants of all kinds, accidents and damage caused by the negligence of people, and exhaustion of an increasing number of global resources; but economic and social damage is also caused by the growing discrepancy between technical competence in different regions, and the everlasting quest for power and military superiority which stops the owners of the relevant technologies from letting others participate in their exploitation. The development in mechanical engineering has determined primarily on developing and humanizing the scientific basis and also on new design principles for yet added powerful and capable machinery and machine systems. The book ""Introduction to Mechanical Engineering"" substantially offers the latest progresses about the important topics of the readers on manufacturing processes and system analysis, thermo-fluid systems, simulations and computer applications, and new approaches in mechanical engineering education and organization systems. It covers state-of-art methodologies by professional researchers from international scientific community and collects original and innovative research studies on major topics of mechanical engineering specifically, fluid mechanics and heat transfer, machine elements analysis and design, machining and product design, wave propagation and failure-analysis and structural mechanics and composite materials. This book will help the readers know more about this topic and help them explore this exciting and fast-evolving field."
