The use of letters in formulas, in place of the actual numbers, simplifies the solution of problems and makes it possible to condense into small space the information that otherwise would be imparted by long and cumbersome rules. The table is given to six decimal places so that it can be used in connection with precision-tool work. By following practical techniques explained in the Guide and cross-referenced to the Handbook, readers will enhance their ability to reach specific information and solutions more quickly and easily.

The lengths of chords and the dimensions and areas of segments are often required in mechanical work. The Guide to the Use of Tables and Formulas in the Machinery’s Handbook, 31st Edition, is designed to maximize the enormous practical value of the latest, greatest edition of this invaluable engineering resource, offering useful information on how to make full use of the Machinery’s Handbook in solving problems on the job. Many formulas are now presented with equivalent metric expres­sions, and metric examples have been added. Find the lengths of chords when the number of divisions of a circumference and the radii are as follows: 30 and 4; 14 and 2½; 18 and 3½. While each Machinery’s Handbook, 31st Edition (MH31) Digital Edition is a single-user version, group discounts are available for qualifying corporations, educational institutions, professional associations, or government bodies purchasing multiple redeemable access codes or a multi-user site license.Example 1: In spur gears, the outside diameter of the gear can be found by adding 2 to the number of teeth and dividing the sum obtained by the diametral pitch of the gear.
