Not illustrated. 1913 Excerpt: ...The engineer will usually be compelled by lack of time to use Method I to check the overhaul computed by subordinates by some one of the more exact methods. CHAPTER VII OVERHAUL COMPUTED FOR THE COMPLEX CASE OF FIG. 38 In this chapter Methods I, IV, V, VI, and VII of overhaul computation are applied, one after another, to the complex problem of Fig. 38. The steps in each method are formally stated. The results are presented in Fig. 36 on the lines beginning with "B," and compared in Sec. 203. This chapter, like the preceding, is designed to serve as a working guide to the computer as soon as the method has been selected. (Fig. 36 faces page 67; Figs. 36a, 37, and 38 face page 12a) 147. Each of the overhaul computation methods, I, IV, V, VI, and VII (Secs. 47-55), will be applied in this chapter to the complex overhaul problem presented by the profile of Fig. 38. It will be observed that the problem of Fig. 38 differs from that of Fig. 19 in two points: (1) In Fig. 38 there are four distinct bodies of material overhauled, while in Fig. 19 there is but one. (2) The work of determining swell-and equating-factors and distribution of material was simple in Fig. 19, but is comparatively complicated in Fig. 38. After we have determined the swell-and equating-factors and the distribution of material, for the case of Fig. 38, we shall find that the further steps of determining limits, centers of gravity, etc., are little more than repetition of the corresponding steps taken in Chapter VI for Fig. 19. To conform to good practice, we first make ready for the computations by gathering all the available data. All the data for the overhaul problem in hand are given in Sec. 148, which is Step I of Method I, and are repeated in Sec. 157. The results obtained by t...
