Heald, Riccardo VII. Hussain, Muhammed Iqbal VIII. A All rights reserved. This book or parts thereof may not be reproduced, stored in a retrieval system, or transmitted in any form without permission of the publishers. Copyright , Industrial Press, Inc. The daily use of such a book, with its various tables and general data, saves a lot of time and labor. To obtain the full value of any handbook, however, the user must know enough about the contents to apply the tables, formulas, and other data, whenever they can be used to advantage. A third objective is to provide test questions and drill work that will enable the H ANDBOOK user, through practice, to obtain the required information quickly and easily. Because of this condensed treatment, any engineering handbook must be primarily a work of reference rather than a textbook, and the practical application of some parts will not always be apparent, especially to those who have had little experience in engineering work.
The questions and examples in this book are intended not only to supplement some of the HANDBOOK material, but also to stimulate interest both in those parts that are used frequently and in the more special sections that may be very valuable even though seldom required. vii Copyright , Industrial Press, Inc. This material is included because much of the world now uses the metric system, also known as the Système International SI , and the movement in that direction continues in all countries that intend to compete in the international marketplace, including the United States. An explanation of the SI metric system is found on Handbook pages to and to A brief history is given of the development of this system, and a description is provided for each of its seven basic units. Factors and prefixes for forming decimal multiples and submultiples of the SI units also are shown.
Another table lists SI units with complex names and provides symbols for them. Tables of SI units and conversion factors appear on pages through Factors are provided for converting English units to metric units, or vice versa, and cover units of length, area, volume including capacity , velocity, acceleration, flow, mass, density, force, force per unit length, bending moment or torque, moment of inertia, section modulus, momentum, pressure, stress, energy, work, power, and viscosity. By using the factors in these tables, it is a simple matter of multiplication to convert from one system of units to the other. Where the conversion factors are exact, they are given to only 3 or 4 significant figures, but where they are not exact they are given to 7 significant figures to permit the maximum degree of accuracy to be obtained that is ordinarily required in the metalworking field. To avoid the need to use some of the conversion factors, various conversion tables are given on pages through The tables for length conversion on pages to will probably be the most frequently used.
Two different types of tables are shown. The two tables on page facilitate converting lengths viii Copyright , Industrial Press, Inc. The table starting on page enables converting fractions and mixed number lengths up to 41 inches into millimeters, in steps of one sixty-fourth of an inch. To make possible such a wide range in a compact table, the reader often must take two or more numbers from the table and add them together, as is explained in the accompanying text. The tables starting on page and have a much more limited range of conversion for inches to millimeters and millimeters to inches. However, these table have the advantage of being direct-reading; that is, only a single value is taken from the table, and no addition is required. For those who are engaged in design work where it is necessary to do computations in the fields of mechanics and strength of materials, a considerable amount of guidance will be found for the use of metric units.
Thus, beginning on Handbook page , the use of the metric SI system in mechanics calculations is explained in detail. In succeeding pages, boldface type is used to highlight references to metric units in the combined Mechanics and Strength of Materials section. Metric formulas are provided also, to parallel the formulas for English units. As another example, on page , it is explained in boldface type that SI metric units can be applied in the calculations in place of the English units of measurement without changes to the formulas for simple stresses. There are other instances, however, where separate tables are needed, such as are shown on pages to for the conversion of revolutions per minute, into cutting speed in feet per minute on pages and , and into cutting speed in meters per minute on pages and It is strongly suggested that all readers, whether or not they are using metric units at the present time, become familiar with the SI System by reading the explanatory material in the Handbook and by studying the SI units and the ways of converting English units to them.
These speeds are variously referred to as surface speed, circumferential speed, and peripheral speed; meaning for each, the distance that a point on the surface or circumference would travel in one minute. This distance usually is expressed as feet per minute. Circumferences are also required in calculating the circular pitch of gears, laying out involute curves, finding the lengths of arcs, and in solving many geometrical problems. Example 1:Find the circumference and area of a circle whose diameter is 8 inches. On Handbook page 66, the circumference C of a circle is given as 3. Therefore, 3. On the same page, the area is given as 0.
For a diameter of 8 inches and a height of 10 inches, the area is 3. Example 3: For the cylinder in Example 2 but with the area of both ends included, the total area is the sum of the area found in Example 2 plus two times the area found in Example 1. Thus, 1 Copyright , Industrial Press, Inc. Example 4:If the circumference of a tree is 96 inches, what is its diameter? Example 5:The tables starting on page of the Handbook provides values of revolutions per minute required producing various cutting speeds for workpieces of selected diameters. How are these speeds calculated? PRACTICE EXERCISES FOR SECTION 1 See Answers to Practice Exercises For Section 1 on page 1 Find the area and circumference of a circle 10 mm in diameter.
Check this value. What is the pressure on the floor in pounds per square inch? Use 0. Cast iron weighs 0. The camshaft rotates at one-half the flywheel speed. Is another method available? A segment of a circle is that part or area between a chord and the arc it intercepts. The lengths of chords and the dimensions and areas of segments are often required in mechanical work. Lengths of Chords. This table is given to six decimal places so that it can be used in connection with precision tool work. Example 1:A circle has 56 equal divisions and the chordal distance from one division to the next is 2. What is the diameter of the circle? The chordal length in the table for 56 divisions and a diameter of 1 equals 0. How can the chordal distance between adjacent holes be determined when the table, Handbook page , is not available? If the sine of this angle is multiplied by the diameter of the circle, the product equals the chordal distance. The sine of Use of the Table of Segments of Circles—Handbook page As explained above the table, the value for any other radius can be obtained by multiplying the figures in the table by the given radius.
For areas, the square of the given radius is used. Thus, the unit type of table is universal in its application. First locate 57 degrees in the center angle column; opposite this figure in the area column will be found 0. Thus, 0. When the depth of the oil is 3 feet, 8 inches, what is the number of gallons of oil? The total capacity of the tank equals 0. One U. gallon equals 0. See also Handbook page 61 for additional information on the capacity of cylindrical tanks. In making a drawing of a gear, how wide should the dividers be set to space 28 teeth on a 3-inch diameter pitch circle? To test the accuracy of the jig, plugs were placed in adjacent holes, and the distance over the plugs was measured with a micrometer. What should be the micrometer reading? What are its surface area and diameter? 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 figures or values for a given problem are inserted in the formula according to the requirements in each specific case. When the values are thus inserted, in place of the letters, the result or answer is obtained by ordinary arithmetical methods. There are two reasons why a formula is preferable to a rule expressed in words. The formula is more concise, it occupies less space, and it is possible to see at a glance the whole meaning of the rule laid down. It is easier to remember a brief formula than a long rule, and it is, therefore, of greater value and convenience. 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. This rule can be expressed very simply by a formula. Assume that we write D for the outside diameter of the gear, N for the number of teeth, and P for the diametral pitch.
It says that the outside diameter D of the gear equals 2 added to the number of teeth N , and this sum is divided by the pitch P. Omitting Multiplication Signs in Formulas. It is only the multiplication sign × that can be thus left out between the symbols or letters in a formula. All other signs must be indicated the same as in arithmetic. If the letter is written first, the multiplication sign is not left out, but the expression is written "A × 3. If the speed of the driven pulley is known, and the problem is to find its diameter or the value of d instead of s, this formula can be rearranged or changed. Rule 1. Rule 2. An independent term preceded by a minus sign may be transposed to the other side of the equals sign if the minus sign is changed to a plus sign.
That the foregoing are correct may be proved by substituting numerical values for the different letters and then transposing them as shown. Rule 3. A term that multiplies all the other terms on one side of the equals sign may be moved to the other side if it is made to divide all the terms on that side. Rule 4. A term that divides all the other terms on one side of the equals sign may be moved to the other side if it is made to multiply all the terms on that side. If, in the rearrangement of formulas, minus signs precede quantities, the signs may be changed to obtain positive rather than minus quantities. All the signs on both sides of the equals sign or on both sides of the equation may be changed. The same result would be obtained by placing all the terms on the opposite side of the equals sign, which involves changing signs. Fundamental Laws Governing Rearrangement. An equation states that one quantity equals another quantity. So long as both parts of the equation are treated exactly alike, the values remain equal.
Suppose we want to solve this equation for h. The expression 2πr in the right-hand member cannot be cancelled because it is not an independent factor, since the numerator equals the difference between T and 2πr2. The rearrangement could be simplified somewhat by direct application of the rules previously given.
