PART ll-BASIC ENGINEERING THEORY 



Chapter 5 Fundamentals of Ship Propulsion and Steering 



Chapter 6 Theory of Lubrication 



Chapter 7 Principles of Measurement 



Chapter 8 Introduction to Thermodynamics 



We cannot proceed very far in the study of naval engineering without 

 realizing the need for basic theoretical knowledge in many areas. To 

 understand the functioning of the machinery and equipment discussed in 

 later parts of this text, we must know something of the principles of me- 

 chanics, the laws of motion, the structure of matter, the behavior of mole- 

 cules and atoms and subatomic particles, the properties and behavior of 

 solids and liquids and gases, and other principles and concepts derived 

 from the physical sciences. 



Chapter 5 takes up the fundamentals of resistance, the development 

 and transmission of propulsive power, and the principles of steering. The 

 remaining three chapters of part II deal with basic scientific theory and 

 engineering principles that have wide— indeed, almost universal— applica- 

 tion in the field of naval engineering. Chapter 6 is concerned with lubri- 

 cation, a subject of vital importance in practically all machinery and 

 equipment. Chapter 7 takes up the principles of measurement and dis- 

 cusses basic types of measuring devices. Chapter 8 provides an introduc- 

 tion to some of the most fundamental concepts of energy and energy 

 transformations, thus establishing a theoretical basis for much of the 

 subsequent discussion of shipboard machinery and equipment. Theoretical 

 considerations of a more specialized nature are discussed in other chap- 

 ters throughout the text, as they are required for an understanding of the 

 particular machinery or equipment under discussion.
