TABLE OF CONTENTS The theory of machines and mechanisms is an applied science that is used to understand the relationships between the geometry and motions of the parts of a machine or mechanism and the forces that produce these motions. The subject, and therefore this book, divides itself naturally into three parts. Part 1, which includes Chapters 1 through 4, is concerned with mechanisms and the kinematics of mechanisms, which is the analysis of their motions. Part 1 lays the groundwork for Part 2, comprising Chapters 5 through 13, in which we study the methods of designing mechanisms. Finally, in Part 3, which includes Chapters 14 through 23, we take up the study of kinetics, the time-varying forces in machines and the resulting dynamic phenomena that must be considered in their design.
The design of a modern machine is often very complex. In the design of a new engine, for example, the automotive engineer must deal with many interrelated questions. What is the relationship between the motion of the piston and the motion of the crankshaft? What will be the sliding velocities and the loads at the lubricated surfaces, and what lubricants are available for the purpose? How much heat will be generated, and how will the engine be cooled? What are the synchronization and control requirements, and how will they be met? What will be the cost to the consumer, both...
