...the stones be perpendicular to that curve : let GHIK represent one of these stones. The upper suiface GH is subjected to a pressure in the direction of...that at E ; put also i for the inclination of GH, i+di for that of KI to the horizon. The pressure on GH may be decomposed into two, one vertically downwards,... | |
