This curve with the values reduced from metres to feet is reproduced below.
The outline of the curve of a valley's sides ultimately depends on the angle of repose of the detritus which covers them, if there has been no subsequent change, such as the passage of a glacier along the v.alley, which tends to destroy the regularity of the crosssection.
The amount of superelevation required to prevent derailment at a curve can be calculated under perfect running conditions, given the radius of curvature, the weight of the vehicle, the height of the centre of gravity, the distance between the rails, and the speed; but great experience 1 See The Times Engineering Supplement (August 22, 1906), p. 265.
1 3p6xcv-ros, shortest, and Xpovos, time), a term invented by John Bernoulli in 1694 to denote the curve along which a body passes from one fixed point to another in the shortest time.
By the device of a hypsographic curve co-ordinating the vertical relief and the areas of the earth's surface occupied by each zone of elevation, according to the system introduced by Supan, 2 Wagner showed his results graphically.
For instance, if the curve is of S-form, the point of danger is when the train enters the contra-flexure, and it is not an easy matter to assign the best superelevation at all points throughout the double bend.
He began first a short ascent, then a drop to a sharp curve he nearly missed, causing him to reduce his speed further.
Here the road was dry and only a few cars passed him before he drifted past a private hot spring, along the wide curve and by the County fairgrounds before entering Ridgway.
Dean pulled out of the curve, searching ahead for a glimpse of his quarry as he continued to hug the right side of the narrow roadway.
M., and navigable for 880 m., rises in the government of Tula and enters the Sea of Azov at Rostov, after describing a great curve to the E.
The radius of a 1-degree curve is 5730 ft., or about 861 chains, of a 15-degree curve 383 ft.
Pierre rushed to the wing, but the heat was so great that he involuntarily passed round in a curve and came upon the large house that was as yet burning only at one end, just below the roof, and around which swarmed a crowd of Frenchmen.
Then they caressed their way up her side, his thumb sliding under her bra and gently up the curve of her breast.
The small car fishtailed around a curve, but she kept up the pace until she no longer saw the man in her rearview mirror.
Usually there were few cars at the site but now, with the early festival climbers in town, the parking lot at the curve of the county road was filled.
The first curve frightened the hell out of him and he knew the brake pressure necessary to slow him from this speed could not be engaged all the way down the mountain without overheating the tiny pads to the point of ineffectiveness.
The bay forms a fairly regular curve, broken on the French seaboard only by the estuaries of the Loire, Garonne, Adour and..
The diurnal variation in summer at the latter station is shown graphically in the top curve of fig.
This three-peaked curve is not wholly pecuiiar to Paris, being seen, for instance, at Lisbon in summer.
To c 1, vary much, then a diurnal inequality derived from a whole year, or from a season composed of several months, represents a mean curve arising from the superposition of a number of curves, which differ in shape and in the positions of their maxima and minima.
His reputation mainly rests on his Introduzione ad una teoria geometrica delle curve piane, which proclaims him as a follower of the Steinerian or synthetical school of geometricians.
If the asymptotes be perpendicular, or, in other words, the principal axes be equal, the curve is called the rectangular hyperbola.
An important property is: the difference of the focal distances of any point on the curve equals the transverse axis.
A diameter is a line through the centre and terminated by the curve: it bisects all chords parallel to the tangents at its extremities; the diameter parallel to these chords is its conjugate diameter.
Bruce, the leader of the Scottish expedition, finds that there is a ridge " extending in a curve from Madagascar to Bouvet Island, and from Bouvet Island to the Sandwich group, whence there is a forked connexion through the South Orkneys to Graham's Land, and through South Georgia to the Falkland Islands and the South American continent."
The ordinates of the curve give the strain in cwts., and the abscissae the distance in miles measured from the Canso end; as the strain is proportional to the depth, 18 cwts.
Also he showed that if such an antenna had its horizontal part swivelled round into various directions the current created in a distant receiver antenna varied with the azimuth, and when plotted out in the form of a polar curve gave a curve of a peculiar figure-of-8 shape.
A third curve, from the south-easternmost promontory of the Peloponnese through Cerigo, Crete, Carpathos and Rhodes, marks off the outer deeps of the open Mediterranean from the shallow seas of the archipelago, but the Cretan Sea, in which depths occur over 1000 fathoms, intervenes, north of the line, between it and the Aegean proper.
Between the Andamans and Cape Negrais intervene two small groups, Preparis and Cocos; between the Andamans and Sumatra lie the Nicobar Islands, the whole group stretching in a curve, to which the meridian forms a tangent between Cape Negrais and Sumatra; and though this curved line measures 700 m., the widest sea space is about 91 m.
When a train is running round a curve the centrifugal force which comes into play tends to make its wheel-flanges press against the outer rail, or even to capsize it.
As she rounded the curve in the staircase, the room became silent.
While resembling the parabola in extending to infinity, the curve has closest affinities to the ellipse.
In another question connected with this, the problem of drawing tangents to any curve, Descartes was drawn into a controversy with Pierre (de) Fermat (1601-1663), Gilles Persone de Roberval (1602-1675), and Girard Desargues (1593-1661).
Fermat and Descartes agreed in regarding the tangent to a curve as a secant of that curve with the two points of intersection coinciding, while Roberval regarded it as the direction of the composite movement by which the curve can be described.
On each side of this is a curve formed of two rows of -HH a From Papers of the British School at Rome, v.
It presents a remarkable resemblance to the adjacent curve, which gives the diurnal variation at mid-winter at the Bureau Central.
