A MANUAL OF RULES, TABLES, AND DATA FOR MECHANICAL ENGINEERS BASED ON THE MOST RECENT INVESTIGATIONS: OF CONSTANT USE STRENGTH OF MATERIALS AND OF ELEMENTARY CONSTRUCTIONS; LABOUR ; WITH AND MANY OTHER USEFUL MATHEMATICAL TABLES. BY MEMBER OF THE INSTITUTION OF CIVIL ENGINEERS; TBD .654 1889 This Work is designed as a book of general reference for Engineers: —to give within a moderate compass the leading rules and data, with numerous tables, of constant use in calculations and estimates relating to Practical Mechanics. The Author has endeavoured to concentrate the results of the latest investigations of others as well as his own, and to present the best information, with perspicuity, conciseness, and scientific accuracy. Amongst the new and original features of this work, the following may be named: In the section on Weights and Measures, the weight, volume, and relations of water and air as standards of measure, are concisely set forth. The various English measures, abstract and technical, are given in full detail, with tables of various wire-gauges in use: and equivalent values of compound units of weight, power, and measure-as, for example, miles per hour and feet per second. The French Metric Standards are defined, according to the latest determinations, with tables of metric weights and measures, equivalents of British and French weights and measures, and a number of convenient approximate equivalents. There is, in addition, a full table of equivalents of French and English compound units of weight, pressure, time, space, and money—as, for example, , pounds per yard and kilogrammes per metre; which will be found of great utility for the reciprocal conversion of English and French units. The tables of the Weight of bars, tubes, pipes, cylinders, plates, sheets, wires, &c., of iron and other metals, have been calculated expressly for this Work, and they contain several new features designed to add to their usefulness. They are accompanied by a summary of the various units of weight of wrought iron, cast iron, and steel, with plain rules for the weight. In the section on Heat and its Applications, the received mechanical theory is defined and illustrated by examples. The relations of the pressure, volume, and temperature of air and other gases, |
