MECHANICAL ENGINEERING

Mechanical Engineering is an engineering discipline that involves the application of principles of Physics for analysis, design, manufacturing, and maintenance of mechanical systems. It requires a solid understanding of key concepts including mechanics, kinematics, thermodynamics and energy. Mechanical engineers use these principles in the design and analysis of manufacturing plants, industrial equipment and machinery, aircraft, heating and cooling systems, watercraft, motor vehicles, medical devices and more.The book Mechanical Engineering is divided into three parts. Part A provides fundamental concepts relating to Mechanical Engineering and definitions of various terms related to this field. Part B studies two-dimensional force systems and analyses. Explanation of basic concepts of force, mass, space and laws of motion is followed by analyses of Varignons Theorem and Force-Couple systems. Exclusive chapters on friction and belt friction have been included to study different mechanisms of friction.Part C concentrates on beams, trusses, frames, stresses and shafts. An exclusive chapter has been devoted to the study of centre of gravity explaining centroids of plane geometrical figures like triangle, circle, trapezium, cylinder, sphere, cone, rod, etc.It is a complete textbook for the students of Mechanical Engineering pursuing B.Tech. All key concepts have been explained in a lucid manner and illustrated with figures herever necessary. It is rich with examples, theoretical as well as numerical questions, simple solutions and diagrams. The students and teachers of Mechanical Engineering will find this book immensely useful.
