Centrifugal force (Mech.), a force whose direction is from a center. Note: When a body moves in a circle with uniform velocity, a force must act on the body to keep it in the circle without change of velocity. The direction of this force is towards the center of the circle. If this force is applied by means of a string to the body, the string will be in a state of tension. To a person holding the other end of the string, this tension will appear to be directed toward the body as if the body had a tendency to move away from the center of the circle which it is describing. Hence this latter force is often called centrifugal force. The force which really acts on the body being directed towards the center of the circle is called centripetal force, and in some popular treatises the centripetal and centrifugal forces are described as opposing and balancing each other. But they are merely the different aspects of the same stress.
Centrifugal impression (Physiol.), an impression (motor) sent from a nerve center outwards to a muscle or muscles by which motion is produced.
Centrifugal machine, A machine for expelling water or other fluids from moist substances, or for separating liquids of different densities by centrifugal action; a whirling table.
Centrifugal pump, a machine in which water or other fluid is lifted and discharged through a pipe by the energy imparted by a wheel or blades revolving in a fixed case. Some of the largest and most powerful pumps are of this kind.

... the greatest quantities, and become much accumulated over the poles of the earth; 2. the common air, or lower stratum of the atmosphere, will be much thinner over the poles than at the line; because if a glass globe be filled with oil and water, and whirled upon its axis, the centrifugal power will carry the heavier fluid to the circumference, and the lighter will in consequence be found round the axis. 3. There may be a place at some certain latitude between the poles and the line on each side the equator, where the inflammable supernatant atmosphere may end, owing to ...

... from England to be indented as servants, permanently, or for a term of years.

The corporal could not waltz, but he could turn—he held fast on by the widow, and with such a firm piece of resistance he kept a centrifugal balance, and, without regard to time or space, he increased his velocity at a prodigious rate. Round they went, with the dangerous force of the two iron-balls suspended to the fly-wheel which regulate the power of some ...
