When the solutions may be taken as effectively dilute, so that the gas laws apply to the osmotic pressure, this relation reduces to E _ nrRT to c1 ey gE c2 where n is the number of ions given by one molecule of the salt, r the transport ratio of the anion, R the gas constant, T the absolute temperature, y the total valency of the anions obtained from one molecule, and c i and c 2 the concentrations of the two solutions.
13 C figure of the three lines YX, XE, EY in the frame, and represents the three forces in equilibrium at the point YXE of the frame.
The direction of YX, being a thrust upwards, shows the direction in which we must go round the triangle YXE to find the direction of the two other forces; doing this we find that the force XE must act down towards the point YXE, and the force EY away from the same point.
Putting arrows on the frame diagram to indicate the direction of the forces, we see that the member EY must pull and therefore act as a tie, and that the member XE must push and act as a strut.
The very names of the islands indicate their nature, for the terminal a or ay is the Norse ey, meaning "island," which is scarcely disguised even in the words Pomona and Hoy.
The Orkneys were the Orcades of classical writers, and the word is probably derived from the Norse Orkn, seal, and ey, island.
If the origin of rectangular axes fixed in the lamina be shifted through a space whose projections on the original directions of the axes are X, u, and if the axes are simultaneously turned through an angle e, the coordinates of a point of the lamina, relative to the original axes, are changed from x, y to X+x cos ey sin e, u+x sin e+y cos e, or X + x ye, u + Xe + y, ultimately.
The name Swansea stands for Sweyn's "ey" or inlet, and may have been derived from King Sweyn Forkbeard, who certainly visited the Bristol Channel and may have established a small settlement at the estuary of the Tawe.
According to a 12th-century chronicle of one of the monks, the name Ramsey is derived from the words "ram," referripg to the tradition of a solitary ram having taken up its abode here, and "ey" meaning an island.
The later termination ey or ea was associated with the insular character of the land, and the prefix with a gravel bank (ceosol; cf.
Huntingdon, Seckington, Edington; -ey, -ea, -y (O.E.
Haxey), is hybrid, Ax being the Celtic uisg, water; ey the Anglo-Saxon for island; and holm the Norse word with the same signification.
