gram of pressures. Because, 0 is the intersection of twoof flic forces or pressures ; therefore, the direction of thethird force must pass through 0 ; but this third force mustalso pass through B. Hence it follows, that 0 B is thedirection of the pressure upon the hinge, and in like man-ner 0 e,… … CONSTRUCTION.
