"When a vessel containing water is whirled rapidly round, why does not the water fall out when the vessel is upside down? Because the centrifugal force, tending to make the water fly from the center, overcomes or balances the attraction of gravitation, which tends to cause the water to fall out." — Wells, 1857

"Suppose a cannon ball, tied with a string to the centre of a slab of smooth marble, and suppose an attempt be made to push this ball with the hand in the direction of b; it is obvious that the string would prevent its going to that point; but would keep it in thei circle. n this case, the string is the centripedal force." -Comstock 1850

"Attach a ball, for instance, to a cord; and , fastening the end of the cord at a point, O, give a quick impulse to the ball. It will be found to move in a circle, ABCD, because the cord keeps it within a certain distance of the centre (sic). Were it not for this, it would move in a straight line." —Quackenbos 1859

"AB is a wheel with a broad rim, or felly. A wine glass partly filled with water is placed on the inner surface of the felly, and the wheel is then made to revolve rapidly round the axle O. If the proper amount of motion be communicated to the wheel, not only will the wine glass keep its place on the felly, but the water also will remain in it..." —Quackenbos 1859

"The upright cyclinder a, is a tube which has a funnel shaped mouth for the admission of the stream of water from the pipe b. This tube is six or eight inches in diameter, and may be from ten to twenty feet long. The arms n and o, are also tubes communicating freely with the upright one, from the opposte sides of which they proceed." -Comstock 1850

"A centrifugal pump differing from an ordinary centrifugal pumps in one feature only. The water rises through a suction pipe S, which divides so as to enter the pump wheel at the center on each side. The pump disk or wheel is very similar to a turbine wheel. it is keyed on a shaft driven by a belt on a fast and loose pulley arrangement at P. The water rotating in the pump disk presses outwards, and if the speed is sufficient a continuous flow is maintained through the pump and into the discharge pipe D. The special feature in this pump is that the water, discharged by the pump disk with a whirling velocity of not inconsiderable magnitude, is allowed to continue rotation in a chamber somewhat larger than the pump. The use of this whirlpool chamber was first suggested by Professor James Thomson." — Encyclopedia Britannica, 1893

"If a body be fastened to a string and whirled, so as to give it a circular motion, there will be a pull on the string that will be greater or less according as the velocity increases or decreases... If the string were cut, the pulling force that drew it away from the straight line would be removed, and the body would then fly off at a tangent; that is, it would move in a straight line tangent to the circle, as shown in Fig. 9." —Hallock 1905
