Présentation de l'éditeur
Geometry of Machinery; the second of theD ynamics of Machinery; and the third of theM aterials, Strength, and Construction of Machinery. Under the head of the Geometry of Machinery, machines are considered with reference to the comparative motions only of their moving parts; and rules are given for designing and arranging those parts so as to produce any given comparative motion. Considering that the object of such rules is to adjust the dimensions of the parts of machines by processes of practical geometry, I have thought it advisable to solve every question by drawing, rather than by calculation, except in a few special cases where calculation is indispensable. Many of the graphic rules thus obtained are made more easy and accurate, and some, indeed, are made possible which were not so before, by the aid of new methods of measuring and laying off the lengths of curved lines. Two chapters of the first part are devoted to the detailed consideration of the movements of single pieces in machines. The remainder of the part relates toP ure Mechanism, as defined and reduced to a system by Professor WILLIS. The order in which the various combinations in mechanism are treated of is different from that adopted by him; but the principles are the same. Several problems in mechanism are solved by methods which, so far as I know, have not hitherto been published; and which possess advantages in point of ease or of accuracy. I may specify, in particular, the drawing of rolling curves, and of some kinds of cams; the construction of the figures of teeth of skew-bevel wheels, and of threads of gearing screws, by the help of the normal section; and some improvements in the details of processes for designing intermittent gear, link-motions, and parallel motions.

Évaluation du vendeur 5 sur 5 étoiles
Paperback. Etat : New. Print on Demand. This book covers the geometrical and dynamic principles and concepts that underlie the design and construction of machinery. Beginning with descriptive geometry principles that are fundamental to the field, the author introduces straight translation, rotation about a fixed axis, and helical or screw-like motion. The text includes rules and formulas for drawing lines and surfaces and for determining the traces and projections of geometrical figures. The author also delves into the strength of materials and the principles of action of cutting tools. This book serves as a comprehensive resource for both the geometry and dynamics of machinery, and the principles presented here are applicable across a wide range of engineering disciplines. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. N° de réf. du vendeur 9781330872406_0
