Mechanical engineering is the branch of engineering concerned with the design, manufacture, installation, operation, and manufacturing processes of engines and machines. It is particularly concerned with forces and motion.
Mechanical engineering has evolved from a technique by mechanics based primarily on trial and error to the application by professional engineers of the scientific method in research, design, and production. The demand for increased efficiency has continually increased the quality of work expected of mechanical engineers and demands higher levels of education and training.
Applications of mechanical engineering can be found in the archives of various ancient and medieval societies. The six classical simple machines were known in the ancient Near East. Wedges and inclined planes (ramps) were known from prehistoric times. The wheel, along with the wheel and axle mechanism, was invented in Mesopotamia (present-day Iraq) in the 5th millennium BC.
The lever mechanism first appeared in the Near East about 5,000 years ago and was used in simple balance scales and in ancient Egyptian technology to move large objects. Levers we real so used in the first crane machine, the shadoof lifting device, which appeared in Mesopotamia around 3000 BC. The earliest evidence of pulleys dates back to Mesopotamia in the early 2nd millennium BC.
About the Book
This book builds on the experience and knowledge gained in “Introduction to Mechanical Engineering Part 1“and is written for undergraduate engineers and those who teach them. These textbooks are not intended to replace traditional lectures, but like Alice, we understand the benefits of writing things down.
This book presents material to supplement the basic units on solid mechanics, thermo dynamics, and fluid mechanics in Part 1. In addition, the reader will encounter units on controls, electromechanical drive systems, and structural vibration. The material has been compiled by the authors primarily from their experience teaching undergraduate engineering students at the University of Nottingham. The knowledge contained in this textbook is derived from lecture notes, research results, and personal experience in the lecture hall and tutorials.
