Σελίδα 26 - Soon shall thy arm, unconquered steam, afar Drag the slow barge or drive the rapid car ; Or, on wide-waving wings expanded, bear The flying chariot through the fields of air...
Σελίδα 296 - As it becomes necessary to have a standard for measuring the amount of heat absorbed or evolved during any operation, in this country the standard unit is the amount of heat necessary to raise the temperature of a pound of water 1° Fah., or from 32° to 33° Fah.
Σελίδα 356 - The specific gravity of a body is the ratio of its weight to the weight of an equal volume of some other body assumed as a conventional standard.
Σελίδα 353 - It is found that the inclined surface of the wheel tire ranges from 1 in 12 to 1 in 20, and, as a matter of course, the direct tendency of the wheels under a load is to descend that incline, so that every vertical blow which the wheels may receive is compounded of two forces, viz.: — the one to crush the wheels in the direction of their vertical plane, and the other to move the lower parts of the wheels together; it will be seen that these two forces have a direct tendency to bend the axle somewhere...
Σελίδα 364 - The modulus of the elasticity of any substance is a column of the same substance, capable of producing a pressure on its base which is to the weight causing a certain degree of compression, as the length of the substance is to the diminution of its length.
Σελίδα 225 - Be it enacted by the Senate and House of Representatives of the United States of America in Congress assembled, That from and after the passage of this act it shall be lawful throughout the United States of America to employ the weights and measures of the metric system...
Σελίδα 380 - Hence we see that if we wish to divide one number by another, we have only to subtract the logarithm of the divisor from that of the dividend; the difference will be the logarithm of their quotient.
Σελίδα 122 - Glory's wreath. No selfish throbs within their breasts are known ; No hope of praise or profit cheers them on : They ask no meed, no fame ; and only seek To shield the suffering and protect the weak.
Σελίδα 355 - ... such as are producing motion, or a change in the direction or velocity of motion. This distinction is wholly artificial, as the same force may act in any of these modes ; it may sometimes be a statical and sometimes an accelerating force. Force is any action which can be expressed simply by weight, and is distinguished by a great variety of terms, such as attraction, repulsion, gravity, pressure, tension, compression, cohesion, adhesion, resistance, inertia, strain, stress, strength, thrust,...
Σελίδα 304 - Latent caloric is that which is insensible to the touch, or incapable of being detected by the thermometer. The quantity of heat necessary to enable ice to assume the fluid state, is equal to that which would raise the temperature of the same weight of water 140°...
