Product Description: Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.

This book is divided into six chapters. In the first some typical simple problems from the range of applications are presented, with as much of the mathematical and physical fundamentals as is needed for the solution of the problems. Whenever possible external principles are used, and when this cannot be done the method of Galerkin serves as the basis for the method of finite elements. Ther second and most extensive chapter deals with the finite elements themselves and shows how the contributions from the different parts of the problem can be made available in an efficient and numerically stable way. The third chapter treats the construction of the corresponding matrices and constant vectors of the complete problem. Some useful hints are given for the implementation of the procedure on a computer. We show how to reduce the order of the resulting algebraic systems and make them easier to solve by optimally numbering the unknowns and eliminating those that can be dropped. In the fourth and fifth chapters practical methods for he numerical solution of large systems of sparse linear equations and eigenvalue problems are described in such a way that the algorithmic formulations allow them to be readily implemented in computer programs. Some of the techniques presented can be found elsewhere only in journals and technical reports. The last chapter contains numerical and graphical results for several practical applications, but are also simple and clear enough to be solvable by the methods presented in previous chapters. It is hoped that the examples given are stimulating enough to motivate readers to solve similar problems of their own choice.

Product Description: This scarce antiquarian book is a facsimile reprint of the original. Due to its age, it may contain imperfections such as marks, notations, marginalia and flawed pages. Because we believe this work is culturally important, we have made it available as part of our commitment for protecting, preserving, and promoting the world's literature in affordable, high quality, modern editions that are true to the original work...read more

Product Description: Originally published in 1903, this book was described by its publisher ---the Scientific American magazine--- as "comprising the physical properties of air from a vacuum to its liquid state, its thermodynamics, compression, transmission, and uses as a motive power in the operation of stationary and portable machinery, in mining, air tools, air lifts, pumping of water, acids, and oils; the air blast for cleaning and painting, the sand blast and its work, and the numerous appliances in which compressed air is a most convenient and economical transmitter of power for mechanical work, railway propulsion, refrigeration and the various uses to which compressed air has been applied; with forty air tables and five hundred and forty-five illustrations...read more
