The pivot of the foreign policy of Christian III.
One pivot of the polar axis is attached to the lower end of this box, and a strong hollow metal cone, terminating in the other pivot, forms the upper part of the polar axis.
Here the crane-post is extended into a long mast and is furnished with pivots at the top and bottom; the mast is supported by two " back ties," and these are connected to the socket of the bottom pivot by the " sleepers."
Great steadiness of card under severe shocks and vibrations, combined with a minimum of friction in the cap and pivot, is obtained with this compass.
(C) The declination axis is mounted on the prolongation of the upper pivot of the polar axis; the telescope is placed at one end of the declination axis and counterpoised by a weight at the other end.
It consisted simply of a light metallic needle balanced on a pivot like a compass needle.
Records of experiments on the friction of a pivot bearing will be found in the Proc. Inst.
Jib cranes can be subdivided into fixed cranes and portable cranes; in the former the central post or pivot is firmly fixed in a permanent position, while in the latter the whole crane is mounted on wheels, so that it may be transported from place to place.
The compass needle is a little steel magnet balanced upon a pivot; one end of the needle, which always bears a distinguishing mark, points approximately, but not in general exactly, to the north,' the vertical plane through the direction of the needle being termed the magnetic meridian.
3 From the first he recognized that his chief duty was to drive the Turks from Europe, or, at least, keep them out of Hungary, and this noble ambition was the pivot of his whole policy.
The cavalry of his left wing stood fast, west of Doon Hill, as a pivot of manoeuvre, the northern face of Doon (where the ground rises from the burn at an average slope of fifteen degrees and is even steeper near the summit) he left unoccupied.
When the rays of the sun or a candle, or dark radiation from a warm body, are incident on the vanes, the dark side of each vane is repelled more than the bright side, and thus the vanes are set into rotation with accelerated speed, which becomes uniform when the forces produced by the radiation are balanced by the friction of the pivot and of the residual air in the globe.
The pivot of this part is the logical principle of contradiction.
C, aluminium cap with sapphire centre; N, N', needles; P, pivot stem with pivot.
Several important points were gained in the latter: the quadrantal deviation could be finally corrected for all latitudes; frictional error at the cap and pivot was reduced to a minimum, the average weight of the card being 200 grains; the long free vibrational period of the card was found to be favourable to its steadiness when the vessel was rolling.
The eye end of the telescope tube is removed - a counterpoise to the object end being substituted in its place - and a prism is inserted at the intersection of the visual axis with the transit axis, so that the rays from the object-glass may be reflected through one of the tubes of the transit axis to an eye-piece in the pivot of this tube.
Mountings of types A and B - that is, with a long polar axis supported at both ends - are often called the" English mounting,"and type C, in which the declination axis is placed on the extension of the upper pivot of the polar axis, is called the" German mounting,"from the first employment of type C by Fraunhofer.
The drawbacks to this plan are (1) the necessarily large size of the upper pivot (viz.
Regarding evil simply as privation, Eckhart does not make it the pivot of his thought, as was afterwards done by Boehme; but his notion of the Godhead as a dark and formless essence is a favourite thesis of theosophy.
Let N be the total pressure sustained by a flat pivot of the radius r; if that pressure be uniformly distributed, which is the case when the rubbing surfaces of the pivot and its step are both true planes, the intensity of the pressure is pN/irr2 (60)
The moment of friction of this pivot is at first almost C, inappreciable from the extreme smallness of the T radius of the circles of contact of the ball and cups, but, as they wear, that radius and the moment of friction increase.
Schiele has invented a pivot which preserves its original figure by wearing equally at all points in a direction parallel to its axis.
This power is acquired by a very massive lever, moving on a pivot bolt in the top of the near side of the staple, and passing across the press to the further side of the frame, at which end the power is applied through the coupling-bar by a bar-handle working from the near side.
Thus the pivot of the Haldane system is the organization of the Territorial Force as a completely self-contained army.
On the 27th the Bulgarian wheel began, but instead of its being carried out on a fixed pivot, the pivot itself was allowed to advance eastward, so that, instead of presenting a united line, the Bulgarians formed a loose echelon, left in advance, which led to successive instead of simultaneous engagements.
Nevertheless, at this same time (June 1834) Lord Palmerston wrote that " Paris is the pivot of my foreign policy."
On the pivot of this distinction Hutcheson turns round from the point of view of Shaftesbury to that of later utilitarianism.
The sole pivot of public life, as he had already become the source of religious authority, thanks to the Jesuits and to Bossuet.
It was probably in Paris, the chief intellectual centre of his time, that Neckam heard how a ship, among its other stores, must have a needle placed above a magnet (the De utensilibus assumes a needle mounted on a pivot), which needle would revolve until its point looked north, and thus guide sailors in murky weather or on starless nights.
The fortress was strengthened by a circle of detached forts, which, after 1870, were modified and completed by the Germans, who treated the fortress as the principal pivot of offensive operations against France.
The important part played by the residual air in the globe had also been deduced by Osborne Reynolds from observing that on turning off the light, the vanes came to rest very much sooner than the friction of the pivot alone would account for; in fact, the rapid subsidence is an illustration of Maxwell's great theoretical discovery that viscosity in a gas (as also diffusion both of heat and of the gas itself) is sensibly independent of the density.
