Mechanical engineering is the study of physical machines involving force and motion. It is a branch of engineering that combines the principles of engineering physics and mathematics with materials science to design, analyze, manufacture, and maintain mechanical systems. Mechanical engineering is one of the oldest and broadest branches of engineering.
Mechanical engineering requires an understanding of the core disciplines of mechanics, dynamics, thermodynamics, materials science, design, structural analysis, and electricity. In addition to these basic principles, mechanical engineers use tools such as computer-aided design (CAD), computer-aided manufacturing (CAM), and product life cycle management to design and analyze manufacturing plants, industrial equipment and machinery, heating and cooling systems, transportation systems, aircraft, watercraft, robotics, medical devices, weapons, and other design and analysis.
Mechanical engineering isa field that originated during the Industrial Revolution in 18th century Europe, but its development can be traced back thousands of years around the world. in the 19th century, developments in physics led to the development of mechanical engineering. Today, mechanical engineers pursue developments in areas such as composite materials, mechatronics, and nanotechnology.
There is also overlap to varying degrees with aerospace engineering, metallurgical engineering, civil engineering, structural engineering, electrical engineering, manufacturing engineering, chemical engineering, industrial engineering, and other engineering disciplines. Mechanical engineers may also work in the field of biomedical engineering,particularlyinbiomechanics,transportationphenomena,biomechatronics,bionanotechnology, and modeling of biological systems.
About the Book
This book is written for undergraduate engineering students and those who teach them. The chapters on solid mechanics, mechanics of materials, fluid mechanics, thermodynamics, electronics, and mechanics are concisely organized to provide the fundamentals of mechanical engineering.
For an introduction to mathematics, see An Introduction to Mathematics for Engineers by Stephen Lee, also published by Hodder Education.
The author has over 120 years of experience teaching undergraduate engineering students, primarily at the University of Nottingham. The content contained in this textbook is drawn from lecture notes, research results, and personal experience in the lecture hall and tutorials.
