But the therapeutic effect is certainly not confined to the central nervous system. Whithersoever the centrifugal nerves lead there the mind-brain system may have its curative influence. In the most startling way that is true for the digestive apparatus. The secretions of the stomach, the activity of the intestines can be influenced to a decree which it is difficult to explain.
It is this situation which has, perhaps more than any other one cause, forced the demand for an educational institution which shall provide something like a homogeneous and balanced environment for the young. Only in this way can the centrifugal forces set up by juxtaposition of different groups within one and the same political unit be counteracted.
Another rule is to multiply the square of the number of revolutions per minute by the diameter of the circle in feet, and to divide the product by 5,870. The quotient is the centrifugal force in terms of the weight of the body. Q. How do you find the velocity of the body when its centrifugal force and the diameter of the circle in which it moves are given?
A body moving in a circle must be acted upon by two forces, one which tends to draw it inwardly, and the other which seeks to throw it outwardly. The former is called centripetal, and the latter centrifugal motion. Gravity, therefore, represents centripetal, and motion centrifugal force.
This change in the nature of the electricity is repeated automatically every fifty miles, and obviates the necessity of revolving machinery, the rails aiding communication. "Magnetism being practically as instantaneous as gravitation, the only limitations to speed are the electrical pressure at the magnets, the resistance of the air, and the danger of the wheels bursting from centrifugal force.
Divide this quadruple height by the diameter of the circle, and the quotient is the centrifugal force in terms of the weight of the body, so that, multiplying the quotient by the actual weight of the body, we have the centrifugal force in pounds or tons.
The alley is built in the shape of a horse-shoe, and the bottom or bed on which the balls roll is hollowed out on a curved line, the outer edge of the bed being raised to prevent the balls from being thrown off the alley by centrifugal force. The balls are rolled from one end of the alley, describe a curved line, and then strike the pins placed at the opposite end of the alley.
Empedocles attributed its state of rest to centrifugal force by the rapid circular movement of the heavens, as water is stationary in a pail when whirled round by a string. Democritus further supposed that the inclination of the flat earth to the ecliptic was due to the greater weight of the southern parts owing to the exuberant vegetation.
This he took to the spring, and, lowering the pan in the pool, began to wash out its contents with the centrifugal movement of the experienced prospector. The saturated red soil overflowed the brim with that liquid ooze known as "slumgullion," and turned the crystal pool to the color of blood until the soil was washed away.
Meanwhile, at one side the drying machines were hard at work; within their cast-iron cylinders bundles of laundry were being wrung dry by the centrifugal force of the steam engine, which was still puffing, steaming, jolting the wash-house with the ceaseless labor of its iron limbs. When Gervaise turned into the entry of the Hotel Boncoeur, her tears again mastered her.
