Sum-of-T-hicknesse-s-of-Plates: Diagram for Determininothe Length of Rivets correct length of the rivet measured from under the head. Asan example assume that a l$-inch rivet is to be used and theplates sum up to the thickness of 2f inches; look for 1-J on theline A B and measure from it to the point where the horizontalintersects the curve marked 2f. The distance (on the full sizediagram; is 5]S inches, which is the correct length under thehead. This is one of those handy diagrams which every engineer anddesigner appreciates for the saving of time arising through itsuse. Those desiring to make one for themselves can just doublethe size of our engraving, vertically and horizontally, and thescale will then be full size so that the sizes can be read off with acommon rule.
