About the Book
This textbook is intended for first and second-year students in a typical college program in mechanical engineering or a related field. Throughout the following chapters, we have attempted to provide a balanced treatment of technical problem-solving skills, design, engineering analysis, and modern technology.
The book begins by describing mechanical engineers, what they do, and what impact they can have (Chapter 1). The seven “elements” of mechanical engineering are then highlighted in Chapters2 (mechanical design), 3 (professional practice), 4 (forces in structures and machines), 5 (materials and stresses), 6 (fluid engineering), 7 (heat and energy systems), and 8 (motion and power transmission).
Applications encountered in the process include sustainable urban infrastructure, virtual and rapid prototyping, nanomachines, internal combustion engines, robotics, sports technology, magnetic resonance imaging, advanced materials, jet engines, micro fluidic devices, automatic transmissions, renewable energy.
What should we learn from this textbook? First of all, you will learn what kind of profession mechanical engineers are, what kind of work they do, and what technical, social, and environmental challenges they solve with the technology they produce. Section 1.3 details a “Top10” list of the achievements of mechanical engineers.
This list will help you recognize how the engineering profession has contributed to your daily life and to society in general around the world. Second, you will see that engineering is a practical endeavor aimed at designing things that work, cost less to manufacture, are safe to use, and have a positive impact on the environment.
