Excerpt from Earthwork Haul and Overhaul: Including Economic DistributionEngineers responsible for overhaul computation may be aided in selecting a method of computation by reading Sections 47 5 5, 146 and 203, and can obtain uniform results by merely direct ing their subordinates to follow the instructions given in Chapter VI or Chapter VII for the selected method.Computers, having been directed to use a given method of computing overhaul, will find in either Chapter VI or Chapter VII a complete plan of procedure under the method.Railroad contractors about to submit bids on work involving overhaul, will find the descriptions of bases and methods of computation of overhaul, given in Chapters V, VI, and VII, a ready means of coming to a definite understanding with rail road engineers as to the way in which the overhaul is to be computed.Students of overhaul, in school or out, will find in Chapters I - V a full presentation of each of the elements of overhaul computation. The beginner is advised to proceed at once to compute the overhaul for some simple case similar to that shown in Fig. 19, by Method IV (sections 89 studying the refer emees under each step no more than may be necessary to execute the step intelligently. A working knowledge of the essentials and routine of one method thus acquired furnishes the ground work necessary for the most profitable study of other portions of the book.Men called upon from time to time, in class-room or office, to give instruction in overhaul computation, will find Part I a treatise from which portions can be selected to fulfill require ments for a course short or long according to the time available for the subject. The fact that the writer is entitled to full membership in this class may be taken as a guaranty that the teacher's interests have not been overlooked herein.Part II is devoted to the elements of the problem of economic distribution, and presents a thorough treatment of the solution of this problem by the use of the mass curve.The attention of those who are familiar with the previously printed matter bearing on haul and overhaul is directed to Sections 2 - 9 (swell and distribution), 15 - 19 (concerning the mass curve), 43, 44 (crosshaul) Chapter VI (data and solution of a simple overhaul problem, by each of eight methods), Chap ter VII (data and solution of complex overhaul problem from practice, by each of five methods), Fig. 36 (statement of over haul computed by various methods), and nearly all of Part II.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
