The application of physics, engineering mathematics, materials science and engineering for designing, analyzing, maintaining and manufacturing mechanical systems is known as mechanical engineering. It makes use of core principles from a large number of areas such as structural analysis, mechanics, dynamics and thermodynamics. Structural analysis is devoted towards analyzing the reasons behind the failure of objects and fixing them. Mechanics studies the forces as well as the effect they have on matter. Mechanical engineering is used to analyze and design heating and cooling systems, industrial equipment, transport systems, aircraft, watercraft, medical devices, etc. Its principles are applied in numerous fields such as robotics, bioengineering, tribology and nuclear engineering. This book discusses the fundamentals as well as modern approaches of mechanical engineering. The topics covered herein offer the readers new insights in this field. This book is appropriate for students seeking detailed information in this area as well as for experts.
