THE purpose of this book is to explain the scientific principles of the action of " PRIME MOVERS," or machines for obtaining motive power, and to show how those principles are to be applied to practical questions. It has been deemed advisable to prefix to the Treatise a very brief Historical Sketch, relating chiefly to the Steam Engine, the only prime mover whose history is known. The body of the work commences with an Introduction, treating of principles, and of mechanical contrivances, which are common to all prime movers, and of the laws of the strength of materials, so far as they are applicable to those machines. Some passages in the Introduction are extracted from a previous Treatise on Applied Mechanics, and abridged or amplified as may be required, in order to suit the purpose of the present Treatise. Such passages are indicated by the letters A. M., with a reference to the number of the corresponding Article in that work. The first part following the Introduction treats of the use of muscular strength to obtain motive power. The second part treats of prime movers driven by the motion of water and of air, including water-pressure engines, waterwheels, turbines, and windmills. The third and largest part treats of engines driven by the mechanical action of heat, and especially of the steam engine. It explains, in the first place, the phenomena of heat, so far as they affect, directly or indirectly, mechanical action in engines; secondly, the laws of combustion and properties of fuel, and the principles upon which economy of fuel depends; thirdly, the laws of the action of heat in producing motive power, or "PRINCIPLES OF THERMODYNAMICS," as applied to the various engines in which that action takes place, and especially to steam engines of all varieties; fourthly, the nature and action of the parts of furnaces and boilers; fifthly, the nature and action of the mechanism of steam engines. The fourth part explains the principles of the action of electro |
