The steepest slope observed occurs off the island of Sapienza, near Navarino, where 1720 fathoms has been obtained only 10 miles from land.
The speed of the ship must therefore be so regulated that the angle of immersion is as great as the inclination of the steepest slope passed over.
The ruling gradient of a section of railway is the steepest incline in that section, and is so called because it governs or rules the maximum load that can be placed behind an engine working over that portion of line.
One of the steepest gradients in England on an important line is the Lickey incline at Bromsgrove, on the Midland railway between Birmingham and Gloucester, where the slope is 1 in 37 for two miles.
The Locher rack, employed on the Mount Pilatus railway, where the steepest gradient is nearly I in 2, is double, with vertical teeth on each side, while in the Strub rack, used on the Jungfrau line, the teeth are cut in the head of a rail of the ordinary Vignoles type.
This range is the water-parting for nearly all the westward-flowing streams of the state, and is by far the steepest and most rugged within Nevada, a number of its peaks attaining a height of 11,000 or 12,000 ft.
The steepest incline outside loo fathoms is to the southeast of the Crimea and at Amastra; the incline to the greater depths is also steep off the Caucasus and between Trebizond and Batum.
The resultant force is therefore in the direction of the steepest pressure-gradient, and this is normal to the surface of equal pressure; for equilibrium to exist in a fluid the lines of force must therefore be capable of being cut orthogonally by a system of surfaces, which will be surfaces of equal pressure.
Giving a compression, and since the slope is steepest there, or - dyldx a maximum, the compression is also a maximum there.
When the displacement is represented by AH'BK'C the particles on each side of B are displaced from it, giving an extension, and since the slope is again the steepest, the extension is a maximum.
But almost everywhere the vegetation serves to smooth the contours of the rugged hills, ferns, mosses and shrubs growing wherever their roots can cling, and leaving only the steepest crags uncovered to form, as in Tahiti, a striking contrast.
One of the steepest gradients in England over such a distance.
Where the hazel bank is steepest, Where the shadow falls the deepest, Where the clustering nuts fall free, That's the way for Billy and me.
