Formula: A X (D + ly- = c BJust to show the difference between the two rules let us assumethat the stays are 6-inch States Rule:120 X 64 = 213 pounds pressure. 36 Figs. 24 and 25 show a brace with nuts inside and outside, butno thread in the sheet. There is also a washer used on theoutside. Stays of this character are generally used where thereis difficulty in putting them in or in removing them. Thehole in the sheet is made large enough to permit the brace toslide through, the inside nut merely acting to keep thejoint. The nut and washer on the outside is a substitutefor the nut and thread in the sheet as in Figs. 23 and 24. In large boilers of high pressure it is found necessary whenusing large braces to increase the thickness of the plate wherethe braces are attached. It may not be necessary for the entirehead to be heavier, as the part held by the flues would be thickenough. Therefore, the part to be increased in thickness would /Double Platel^L^Head.
