improvements byProf. J. B. Johnson and Prof. H. T. Eddy on the methodoriginally given by the author. The roller will be assumedto be composed of indefi-nitely thin vertical slices par-allel to its axis. It will alsobe assumed that the layersor slices act independentlyof each other. Let E be the… … Let w = intensity of pressure at A. / = any other point. /• = total weight which the roller sustains per unit of length. X be measured horizontally from A as the origin. ^ = AC. -f = DC. 444 APPENDIX II. From Fig. I : h h h h ,. d = AC = AB + BC = w (^ + I);And (I). AC = AB + BC:=^p(^ + ^)l. . . .…
