This book presents and illustrates the concepts, principles and analytical problem-solving methodologies in engineering mechanics.It is divided into ten chapters.Chapter 1 gives an introduction to engineering mechanics and its fundamental concepts.Since the international system of units (SI units) receives worldwide recognition, SI units are also introduced in chapter 1 and used throughout the book.As a convenient tool, vector algebra is then presented in chapter 2. Chapter 3 discusses the simplification of a system of forces and couples or a distributed loading.The conditions and equations of equilibrium for a particle and a rigid body are developed and applied, especially to equilibrium problems of a system of rigid bodies, such as frames, machines and trusses, in chapter 4. Applications to equilibrium problems involving frictional forces are discussed in chapter 5.The kinematics of particles is treated in chapter 6, followed by a discussion of planar kinematics of rigid bodies in chapter 7. Kinetics are discussed in chapter 8 (equations of motion), chapter 9 (work and energy), and chapter 10 (impulse and momentum).In each of these three chapters, applications to only particles' motion are considered first and then more difficult and practical applications associated with the motion of rigid bodies are addressed.Each chapter begins with the objectives of the chapter.Then it consists of theory sections, example problems and homework problems.The example problems serve double purposes of amplifying the theories and demonstrating the neat work that students should cultivate in their own solutions, and are presented in a logical and orderly manner.Sometimes multiple solutions are provided for a problem, trying to inspire students to broaden their thinking and better understand various principles and methods.For some examples, there is a "RETHINK" section, where in-depth discussions or enlightening questions are presented.Most of the problems are of practical nature and should appeal to engineering students.They are meticulously designed to help students master the principles of mechanics and their applications.
