Synopsis

Excerpt from Statics by Algebraic and Graphic Methods: Intended Primarily for Students of Engineering and Architecture

Problems involving much finding and summing of products or involving trigonometric or complicated geometric relations are found to be an advantageous field for the use of graphic methods, and in this field, graphic methods assume a place of relative importance.

Problems in equilibrium are of precisely this sort, and graphic methods of dealing with them have been developed very extensively, and even named, as a body, Graphical Statics, in distinction from the body of algebraic methods in statical prob lems - called Analytical or Algebraic Statics. All these terms, as pointed out in the preface, seem objectionable to the writer and will not be used further in this work. The terms algebraic method and graphic method will be used in their stead.

The underlying principles and the procedure in both meth ods are, of course, scientifically correct, but they differ in the degree of precision attainable. The precision of results in algebraic computation depends upon the extent to which deci mals or significant figures are carried out, and in graphical work upon care and skill in draughting. In the former case absolute precision may be approached as closely as the com puter may care to go, but in the latter early bounds are set by the limitations of draughting appliances and human eyesight. Sometimes it is worth while to use a combination of the two by sketching more or less roughly the desired diagrams and calculating trigonometrically instead of scaling the lengths of resulting lines. This of course is the algebraic method itself so far as precision goes.

About this title

Product Description

Excerpt from Statics by Algebraic and Graphic Methods: Intended Primarily for Students of Engineering and Architecture This volume has been written in the hope of helping students of engineering and architecture to acquire a knowledge of Statics which will include the power to apply it correctly in professional work. To this end an attempt has been made to carry out several specific purposes, prominent among which may be mentioned the following: 1. To give much attention to the starting points of the science, and to make as clear as possible the course of deduction therefrom. 2. To point out the inherent mathematical limitations of pure Statics, and to show how all its important problems are solved. 3. To develop algebraic and graphic methods of solution, or, if one prefer the terms, Analytical and Graphical Statics, side by side and with equal thoroughness. 4. To present a graded set of problems illustrating not only universal principles but also how Statics is used in engineering practice. 5. Finally, to keep the book of a size commensurate with the small amount of new matter which the reader, versed in the simplest operations of elementary mathematics, need master to gain the desired end. It may be pointed out that the phrases Analytical Statics and Graphical Statics are avoided. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
