A. One rule frequently adopted is as follows: Multiply the mean diameter of the rim by the number of its revolutions per minute, and square the product for a divisor; divide the number of actual horse power of the engine by the number of strokes the piston makes per minute, multiply the quotient by the constant number 2,760,000, and divide the product by the divisor found as above; the quotient is the requisite quantity of cast iron in cubic feet to form the fly-wheel rim.
He proposed for that unit, such a fraction of pure silver as would be a common measure of the penny of every state, without leaving a fraction. This common divisor he found to be 1/1440 of a dollar, or 1/1600 the crown sterling. The value of a dollar was, therefore, to be expressed by 1440 units, and of a crown by 1600; each unit containing a quarter of a grain of fine silver.
The uniform employment of twelve as the divisor and multiplier in tables of weight, distance, time, and space, as well as in arithmetical notation, has all the conveniences of the decimal system of France, and some others besides due to the greater convenience of twelve as a base.
A. To find the proper dimensions for the teeth of a cast iron wheel: multiply the diameter of the pitch circle in feet by the number of revolutions to be made per minute, and reserve the product for a divisor; multiply the number of actual horses power to be transmitted by 240, and divide the product by the above divisor, which will give the strength.
This, reduced to the greatest common divisor, or, add numerators and denominators=17/21!"
I wrote a note to Georgiana, asking whether it would interfere with Sylvia's Greatest Common Divisor if I presented her with a profusion of elegant flowers on that occasion.
His theory of his own capacity for domesticity, though sincere, was strictly academic. He had no more idea of putting it into practice than he had of proving in his own person, before his proper time, the doctrine of eternal life. Now, into the familiar sum of existence, which he knew from divisor to quotient, was suddenly shot a new factor a woman.
"Let's foind out an' give him a surprise party an' a church donation some night." "What does he come here so much for, anyhow?" I questioned. "I don't know," replied O'mie. "Why can't he stay Injun? What'll he do wid the greatest common divisor an' the indicative mood an' the Sea of Azov, an' the Zambezi River, when he's learned 'em, anyhow?
The remainder was too large; no it was too small; no it was he didn't know what! Everybody was watching him; he heard a boy laugh softly. He had made a mistake, then; what was it? where was it? Mr. Burrows' voice came to him, calm and kind: "Edward, don't get excited. Look at your remainder closely; take the first figures of divisor and remainder nine in thirty-one, how many times?
"Then she will never need the Greatest Common Divisor. I have known many thousands of human beings, and none but teachers ever have the least use for the Greatest Common Divisor." "But she needs to do things that she dislikes. We all do." I smiled at the memory of a self-willed little bare foot on a log years ago.
