Principles of naval engineering - Historic Naval Ships Association

PART ll-BASIC ENGINEERING THEORYChapter 5Chapter 6Chapter 7Chapter 8Fundamentals of Ship Propulsion and SteeringTheory of LubricationPrinciples of MeasurementIntroduction to ThermodynamicsWe cannot proceed very far in the study of naval engineering withoutrealizing the need for basic theoretical knowledge in many areas. Tounderstand the functioning of the machinery and equipment discussed inlater parts of this text, we must know something of the principles of mechanics,the laws of motion, the structure of matter, the behavior of moleculesand atoms and subatomic particles, the properties and behavior ofsolids and liquids and gases, and other principles and concepts derivedfrom the physical sciences.Chapter 5 takes up the fundamentals of resistance, the developmentand transmission of propulsive power, and the principles of steering. Theremaining three chapters of part II deal with basic scientific theory andengineering principles that have wide— indeed, almost universal—applicationin the field of naval engineering. Chapter 6 is concerned with lubrication,a subject of vital importance in practically all machinery andequipment. Chapter 7 takes up the principles of measurement and discussesbasic types of measuring devices. Chapter 8 provides an introductionto some of the most fundamental concepts of energy and energytransformations, thus establishing a theoretical basis for much of thesubsequent discussion of shipboard machinery and equipment. Theoreticalconsiderations of a more specialized nature are discussed in other chaptersthroughout the text, as they are required for an understanding of theparticular machinery or equipment under discussion.83
