Transcriber's Notes:

DISCLAIMER: This document should NOT be used to engineer any bridge
projects! Many typesetting errors were found, and it is possible that
there are further errors in the information that were not caught.

Formulas have been provided both as ASCII and TeX following in brackets.
Bold headings are handled with equal signs before and after the bold text.
Italicised text uses the standard underlines before and after the text.
Fractions are expressed in the format: 2-1/4 means two and one quarter.

The page numbers listed below are project page numbers.
(The original book used Roman numerals to number the pages.)

Note that the book uses the "long" ton equal to 2,240 pounds.

CORRECTIONS MADE:

1. Page 8--the formula for "d" must use a cube root, which is how it
is shown here, but the '3' to indicate a cube root is not found in
the original document.
2. Page 8--typo in word 'sectien'--changed to 'section'.
3. Page 10--Value for working comp. strength of cast iron in the
table had a typo (25,v00). Since other values use round numbers,
it is assumed the value should be 25,000.
4. Page 10--Two other typos. Changed 'the the' to 'the', and in
table heading, origin
