a vertical plane such as AB (Fig. 36), the pressure p, which is exerted on the plane, is applied to the symmetrical centre 0. But when the plane is struck obliquely, the stream-lines follow paths similar <. to those shown in Fig. 37. A loss ^ of speed (and perhaps even a back- ward motion) of the… … FIG. 37. If from every point of a surface perpendiculars are drawn of a length proportional to the pressure at each point, a diagram is obtained similar to the lower portion of Fig. 38 (under surface). Behind the plane, on the contrary, a negative pressure is produced wherein are eddies, and its…
