Finally, the watt meter, an instrument recently developed by his firm, was shown in operation. This consisted simply of a coil of thick conductor suspended by a torsion wire, and opposed laterally to a fixed coil of wire of high resistance.
The little cany carriage partly perhaps from the dreadful torsion of the wheels in its recent movement, partly from the thundering blow we had given to it as if it sympathized with human horror, was all alive with tremblings and shiverings. The young man sat like a rock. He stirred not at all. But his was the steadiness of agitation frozen into rest by horror.
From time to time a slow torsion and crisping of all his nerves, beginning at his ankles, spread to every corner of his body till he had to shut his fists and teeth against the blind impulse to leap from his bed screaming. His hands felt light and, as he told himself, "jumpy."
One of the methods consists in continuing the torsion until the part held in the forceps is detached. When, however, the operator does not intend to produce that effect, he ceases, after from four to six revolutions of the vessel on its axis for the small arteries, and from eight to twelve for the large ones. The hemorrhage instantly stops.
It is known that Cavendish was the first who succeeded by means of the torsion balance in effecting fairly precise measurements. This method has been again taken in hand by different experimenters, and the most recent results are due to Mr Vernon Boys.
"No," replied the man; "I will not, that is certain. And I mean to divide these playthings with you here." And so saying he applied a sudden and severe torsion to the lad's wrist. Harry could not suppress a scream, and the perspiration burst forth upon his face.
It will surprise many, perhaps, to learn that in Foucault's original mode of suspension the upper end of the wire bearing the pendulum bob was fastened to a metal plate by means of a screw. It might be supposed that the torsion of the wire would appreciably affect the result. In reality, however, the torsion was very small.
The special risks of incised wounds are: division of large blood vessels, leading to profuse hæmorrhage; division of nerve-trunks, resulting in motor and sensory disturbances; and division of tendons or muscles, interfering with movement. Treatment. If hæmorrhage is still going on, it must be arrested by pressure, torsion, or ligature, as the accumulation of blood in a wound interferes with union.
In fact, on the contrary, the attachment of the dorsal fin is continued forward where it is required for its mechanical function, regardless entirely of the morphology of the head. This is even more clearly evident in the structure of the jaws and teeth. These are entirely unaffected by the torsion of the interorbital part of the skull.
The contrary takes place as regards molecular elasticity. In tempered steel the molecules are extremely rigid, and in soft iron its molecular elasticity is at its maximum. Its free motion differs entirely from that given it by torsion or stress.
