The pieces of lunarium were fastened in like manner to screws, which passed through the top of the machine; so that by turning them in one direction, those metallic pieces would fly into the air with the velocity of a rocket.

Indeed we may consider the velocity with which an animal moves, as a sure indication of the perfection of its vision.

Q.But the velocity in what terms? A.In feet per second.

The bullet of this cartridge, when fired from the rifle, starts with an initial velocity at the muzzle of 2,700 feet per second.

The Brahmin was wholly absorbed in calculations for the purpose of adjusting our velocity to the distance we had to go, his estimates of which, however, were in a great measure conjectural; and ever and anon he would let off a ball of the lunar metal.

The Orangin are there also, who bind smooth bones under their feet, and thrust themselves with such velocity over the ice and snow, as to overtake beasts in the chase.

Friction, nature of, does not vary as the rubbing surfaces, but as the retaining pressure; does not increase with the velocity per unit of distance, but increases with the velocity per unit of time; measures of friction; effect of unguents; kind of unguent should vary with the pressure; Morin's experiments; rule for determining proper surfaces of bearings; friction of rough surfaces.

It thus resembles more the primer, for a rich mixture of gasoline and air burns at a greater velocity than a poor one.

Q.How comes it, then, that while the body falls 64-4/12 feet in two seconds, it falls only 16-1/12 feet in one second; or why, since it falls only 16-1/12 feet in one second, should it fall more than twice 16-1/12 feet in two? A.Because 16-1/12 feet is the average and not the maximum velocity during the first second.

We define it conceptually as [s/t], but the s and t are only artificial cuts made after the fact, and indeed most artificial when we treat them in both runners as the same tracts of 'objective' space and time, for the experienced spaces and times in which the tortoise inwardly lives are probably as different as his velocity from the same things in Achilles.

The impelling force is gravity, which urges the body with a force proportionate to the distance descended, and if the velocity due to the descent of a body through a given height be spread over a great horizontal distance, the speed of the body must be slow in proportion to the greatness of that distance.

In a screw vessel the same law applies, so that with any given pressure on the pistons and discarding the consideration of friction, it will follow that whatever be the thrust exerted by a paddle or a screw vessel, it must remain uniform whether the vessel is in motion or at rest, and whether moving at a high or a low velocity through the water.

"Since the ship that escaped headed recklessly at its highest velocity toward a certain area of the Belt, we can reasonably assume that the pirates' base is situated on an asteroid not far from that area.

On descending to the camp, I started a fragment of rock of a few tons weight, which rushed with fearful velocity towards the deep gorge in which the horses were feeding.

Philosophers have calculated the difference of velocity between sound and light; but who will attempt to calculate the difference between speech and thought!"Horne Tooke's Epea Pteroenta, Vol.

When the pitch of a screw increases in the direction of its diameter, the central part of the screw will advance with only the same velocity as the water, so that it cannot communicate any centrifugal velocity to the water; and the whole slip, as well as the whole propelling pressure, will occur at the outer part of the screw blades.

But the vessel of the Rover was in view, in all the palpable and beautiful proportions of her admirable construction Instead of lying in a state of rest, as when he left her, her head-yards had been swung, and, as the sails filled with the breeze, the stately fabric had he gun to Marve gracefully, though with no great velocity along the water.

Coalchester will spin soon, and then the disappointed fields around it, then the neighbouring towns would join the reel, and so on and on, faster and faster, madder and madder, till even London itself moves, and the world that changes its axis at the will of any strong spirit will whirl its immeasurable velocities around the vortex pulpit of Theophilus Londonderry.

The apparatus consists essentially of a nozzle through which sand can be propelled at a high velocity against the test specimen by means of a steam jet.

Secondly, its adaptability to high rates of speed, and the provision that has been made to withstand such velocities for a reasonable time.

The direction of immediate improvement In ordnance for iron-clad warfare appears to be the abandonment of cast-iron, except as a barrel to be strengthened by steel; binding an inner tube with low-steel hoops having a successively increasing initial tension; and the use of spherical shot at excessive velocities by means of high charges of powder in bores of moderate diameters.
