If we change any one of these three dimensions in a stack thedraft will also be changed. But by making a correlative change inthe other two dimensions the new stack can be so designed thatthe same draft will be produced, ihus we can still retain a stackthat will produce the same draft by making combinations with d, 1 and X. The following cases are possible : Unchanged. d Ix 2 I dx 3 X dl i , nrthing d, I, x making four different forms. In the conical stack as shown in Fig. 70, there must be added to the three preceeding dimensions a fourth, or the flare (—I of that portion of the stack lying above the point of smallest cross-section,whi
