Book Description

Excerpt from Empirical Design This book has been planned especially to meet the needs of the second year students in the Department of Machine Design of Cornell University. It is hoped, however, that the material is of a nature and the arrangement such as to meet. In a fair degree, the needs of other technical schools and colleges for a course in design to follow the elementary Mechanical Drawing and Descriptive Geometry before the student has had the necessary preparation in Mechanics for a course in theoretical design. It is intended to give in a convenient form such tables, formulas and curves for the empirical proportioning of machine parts as are necessary in a brief course in Empirical Design, and such instruo tion as to the methods of their derivation and use that the student, upon the completion of the course, may be able to use material of this nature understandingly and to derive new material if he so desires. The data have been collected at different times and have been in use in teaching this course in Cornell University for a considerable period. The purpose and manner of using the various machine parts is explained in detail for the benefit of those students whose previous training has left them wholly unfamiliar with machinery. In the descriptions and explanations a fair knowledge of the principles of Mechanical Drawing, Descriptive Geometry and Analytical Geometry has been assumed. NO attempt has been made to intrude upon the field of the engineer's handbook but the proportions have been carefully com piled with the intent that any here given shall be reliable within the limits of good design, and some of the more commonly used mathematical tables have been added with a View to making it a desirable book for reference in the more advanced classes in Machine Design. Acknowledgment is due to Professors E. H. Wood and C. D. Albert and to Mr. L. J. Bradford for suggestions and criticisms. The author is indebted to Professor Wood for the use of the pro portions derived by him for many of the machine parts described.
