Reed's Engineers' Hand Book

To the Board of Trade Examinations for First and Second

Class Engineers.

By " EXTRA CHIEF."

Illustrated by 450 Diagrams and Plates.

TWENTY-FIRST EDITION, Revised and Enlarged.

Price 27/6 Net. By Post 28/6.

Part I. Practical Mathematics. Part II. General

Engineering Knowledge.

With 310 Elementary Questions and Answers.

The Practical Mathematics portion of the work has been com-
pletely remodelled to conform with the great changes that have
been inaugurated in this part of the examinations. The prominent
facts in connection with elementary mathematics, mechanics,
heat and steam, are set out in simple language, and illustrated
by examples. About sixteen complete sets of recent examina-
tion papers are given for each grade. Skeleton solutions for all
examples are included, but, for backward students and others
who desire the complete working where all the detailed steps
are clearly and fully shown, a " KEY TO THE ENGINEERS' HAND
BOOK," has been published.

Part II., comprising sections on Electricity, Oil Motors, Refri-
geration, Turbines, Machine Drawing, etc., contains much valuable

1



information concerning the running and maintenance of the main
and auxiliary machinery.

CONTENTS. PART I. The Simple Rules of Arithmetic. Elemen-
tary Mensuration. The Simple Machines. Heat Steam Power.

Reed's Engineers' Hand Book

To the Board of Trade Examinations for First and Second
Glass Engineers.

Containing the working of all the Questions given in the
Examination Papers.

8/6 Net. By Post 9/-.

The Handbook contains skeleton solutions to all the examples,
but the Key shows very fully how all the answers are obtained.
A student may arrive at the correct answer by a roundabout way
of his own, but, with the aid of the Key, he may see how the labour
entailed might be shortened, or the alternative method suggested
may be useful in solving problems of a similar character.
Students should bear in mind that at least half marks are given
for the setting down or " stating " of the questions and the re-
mainder for the correct numerical figuring.
