Disruptional Phenomena It is clear that the material at different parts of the rotating spheroid will be energised to varying degrees.
This spheroid having become cool and somewhat stiff, is next carried to the bottoming hole (like fig.
The horizontal diameter of the copper spheroid A, is not less than 5 feet; the depth of the under hemisphere is at least 18 inches from the level of the plane; and the height of the dome-cover is 2 feet.
Do not frighten yourself," answered Barbicane, "Our spheroid is at her post, but we cannot see her from this side.
It may also be noticed that upon the lunar spheroid the South Pole is much more continental than the North Pole.
The spheroid came back true, and John tucked it against his chest as, with head well down, he hurled himself forward.
The spheroid flew straight and true across the room, and caught John Stiver on the chin.
Ray Dutton caught it, and, tucking the spheroid under his arm he sprinted down over the chalkmarks, gathering speed at every stride.
He had to do a nimble sprinting act before he was ready to receive the spheroid on his ten yard line.
It must have become an oblate spheroid flattened at the poles and bulging at the equator, rotating faster and faster as it contracted.
Of course its real shape is approximately a spheroid of revolution, and the values of the axes most commonly employed are those of Clarke or of Bessel.
Useful tables, based on Clarke's spheroid of 1866, have been published by the war office and by the U.
Gosselin concludes from this that Eratosthenes and Polybius gave to the earth the form of a spheroid flattened at the poles.
The spheroid in consequence is not so minutely exact as one might be made by the aid of a turner’s instrument, or as would answer the definition of a geometer, still in general appearance, and looked at roughly, it is a spheroid.
Flood hit it a mighty "poke" and away the horsehide spheroid sailed, well over the head of Holly Cross in center field.
Let us assume ex hypothesi the form to be that of a spheroid and see where it leads us.
Our conception of ultimate matter is reduced to that of an oblate spheroid described by the revolution of an ellipse on its own minor axis!
A slight deformation of the earth will thus result; and the axis of figure of the distorted spheroid will no longer be PP, but a line P'P' between PP and RR.
Geographical latitude, which is used in mapping, is based on the supposition that the earth is an elliptic spheroid of known compression, and is the angle which the normal to this spheroid makes with the equator.
We may consider this spheroid to be that of the earth, the ellipticity being greatly exaggerated.
It is therefore less than the motion in an absolutely rigid spheroid in the proportion RP' : RP.
Illustration] To show the cause of this motion, let BQ represent a section of an oblate spheroid through its shortest axis, PP.
An obstacle to concentration, however, exists in the centrifugal force, which at this stage bears a far higher ratio to gravity than afterwards, and in a gaseous spheroid must produce a very oblate form.
On considering what must happen in a rotating gaseous spheroid having currents moving as above described, we shall see that external condensation is a corollary.
This rarefied and cooled mass must be still more rarefied and cooled in its progress over the surface of the spheroid to the equator.
While the force of gravitation draws all the atoms of the spheroid together, their tangential momentum is resolvable into two parts, of which one resists gravitation.
In a rotating nebulous spheroid that is concentrating into a planet, there are at work two antagonist mechanical tendencies--the centripetal and the centrifugal.
Starting, then, with a rotating spheroid of aeriform matter, in the later stages of its concentration, but before it has begun to take a liquid or solid form, let us inquire what must be the actions going on in it.
Though it is not possible to calculate what proportions these two tendencies had to each other in the genetic spheroid which produced each planet; it is possible to calculate where each was the greatest and where the least.
It is the surface of this inner spheroid of denser gases to which our reasoning points as the place of earliest condensation.
Such being the constitution of a concentrating spheroid of gaseous matter, where will the gaseous matter begin to condense into liquid?
Thus, then, according to the oblateness of the spheroid and the bulkiness of the detached ring, will the greatest thickness of that ring be in the direction of its plane, or in a direction perpendicular to its plane.
When by the accumulated action of incident forces this equilibrium is {229} disturbed, the spheroid is supposed to turn over until it settles on an adjacent facet once more in stable equilibrium.
At length when it has assumed the shape shown in a figure titled "Planetary spheroid just becoming unstable" (Fig.
As the shrinkage and corresponding increase of density proceed, the planetary spheroid becomes more and more elliptic, and the succession of forms constitutes a family classified according to the density of the liquid.
It is a minute spheroid in which the best microscope will reveal nothing but a structureless sac, enclosing a glairy fluid, holding granules in suspension.
The spheroid specimen made of hard lava, possibly trap, shown in Fig.
Then Clairaut, from the assumption that the earth is a spheroid of equilibrium, derived a theorem from which the ellipticity of the earth can be derived from values of the intensity of gravity.
Laplace showed that the surfaces of equal density might have any nearly spherical form, and Stokes showed that it is unnecessary to assume any law of density as long as the external surface is a spheroid of equilibrium.
If Thomas Roch is to be credited, this fulgurator could shatter the terrestrial spheroid at one blow.
A few thousand tons of it would burst our spheroid and scatter the fragments into space.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "spheroid" in a variety of sentences. We hope that you will now be able to make sentences using this word.
