From the lower flange of a suspended !; runway, made of a single I section, run wheels, from the axles of which the transporter is suspended.
3), mounted on a strong steel bolt having a broad base flange, is employed.
Broad, having at the inner side an upright ledge or flange, 3 in.
Subsequently, to increase the strength, a similar flange was added below the rail.
At one end of each rail the flange spread out to form a foot which rested on a cross sleeper, being secured to the latter by a spike passing through a central hole, and above this foot the rail was so shaped as to form a socket into which was fitted the end of the next rail.
And the Vignoles or flange rail.
In the United States a committee of the American Society of Civil Engineers, appointed to consider the question of rail manufacture in consequence of an increase in the number of rail-failures, issued an interim report in 1907 in which it suggested a range of carbon from 0-55 to 0-65% for the heaviest sections of Bessemer steel flange rails, with a phosphorus maximum of 0.085%; while the specifications of the American Society for Testing Materials, current at the same period, put the carbon limits at o 45 to 0-55%, and the phosphorus limit at o io.
A side wind causes excessive flange friction on the leeward side of the train, and increases the tractive resistances therefore very considerably, even though its velocity be relatively moderate.
-; the upper canines being long sabre-like weapons, protected by a descending flange on each side of the front of the lower jaw.
To this adapter is attached a flat circular flange h.
A smoothly on the flange h.
Rotation is communi cated by a pinion, turned by the handle c (concealed in the figure), which works in teeth cut on the edge of the flange h.
The slowest speed is given by means of a tangent screw which is carried by a ball-bearing on the flange of the telescope sleeve, whilst its nut is double-jointed to a ring that encircles the flange of the heliometer-tube.
They agree, for instance, with that family in the presence of a descending flange at the hinder end of each side of the lower jaw; but their dentition is of a more generalized type, comprising the full series of 44 teeth, among which the incisors and canines are of normal form, but specially enlarged, and developing roots in the usual manner.
It shows the characteristic hippopotamus-flange to the lower jaw, but has also a large descending process from the jugal bone of the zygomatic arch of the skull.
§ 307) that for a cylindrical tube of radius R, provided with a flat extended flange, the loop may be regarded as about o 82 R, in advance of the end.
Using this result Rayleigh found the correction for an unflanged open end by sounding two pipes nearly in unison, each provided with a flange, and counting the beats.
Then the flange was removed from one and the beats were again counted.
The change in virtual length by removal of the flange was thus found, and the open end correction for the unflanged pipe was o 6 R.
Of the internal stresses, which balance the external forces, shows that most of the material should be arranged in a top flange, boom or chord, subjected to compression, and a bottom flange Or chord, subjected to tension.
The top flange consisted of cast iron hollow castings butted end to end, and the struts were of cast iron.
The lower flange and ties were flat wrought iron links.
These piles have a flat flange at the bottom, and water is pumped in at the top of the pile, which is weighted to prevent it from rising.
A main girder consists of an upper and lower flange, boom or chord and a vertical web.
If A t A, are the cross sections of the tension and compression flanges or chords, and h the distance between their mass centres, then on the assumption that they resist all the direct horizontal forces the total stress on each flange is Ht=H,=M/h and the intensity of stress of tension or compression is f t = M/Ath, f c = M/Ach.
The value of H is equal to the maximum tension on the bottom flange, or compression on the top flange, of a girder of equal span, equally and similarly loaded, and having a depth equal to the dip of the suspension bridge.
Borchers also used an externally heated metal vessel as the cathode; it is provided with a supporting collar or flange a little below the top, so that the upper part of the vessel is exposed to the cooling influence of the air, in order that a crust of solidified salt may there be formed, and so prevent the creeping of the electrolyte over the top. The carbon anode passes through the cover of a porcelain cylinder, open at the bottom, and provided with a side-tube at the top to remove the chlorine formed during electrolysis.
Along each side of the body stretches a horizontal fin and a similar flange surrounds the tail.
17) be a section of the polar axis; it is then easy to adjust the weight P attached to its lower end so that the centre of gravity X of the whole moving parts of the instrument shall be in the vertical (V V) of a line passing through the apex of the hollowed flange p q at q, which flange forms part of the polar axis.
This framework is provided with guides on which the platform, whilst preserving its horizontality, is V the observer has to follow the eye-end in a comparatively small circle; another good point is the flattening of the cast-iron centrepiece of the tube so that the flange of the declination axis is attached as near to the axis of the telescope tube as is consistent with free passage of the cone of rays from the object-glass.
15), the attachment to the flange of the declination axis is placed as close as it can be to the axis of the tube without interfering with rays converging from the object-glass to any point in the field of view.
Their decoration is confined to a band round the upper part of the pot, or often only a projecting flange lapped round the whole rim.
It is usual in both girders and beams to provide not only for the safe support of the greatest possible distributed load, but for the greatest weight, such as that of a safe or other heavy piece of furniture which may be moved over the floor at its weakest points, the centres of the girders and beams. It must always be borne in mind that the formulae for the ultimate strength of the " I " beams only hold good when the upper chord or flange is supported laterally.
The Broad Flange Differdange Beams are claimed by the manufacturers to be stronger and to minimize weight for use as girders; they are made in twenty-one different sizes with flanges from 88 to i 2 in.
Where the width of the flange is considerable it is first covered with metal lath secured to the under side of the floor masonry.
It will be enough to say here that the mountainous region belongs to the great orographical flange which runs from south-west to northeast along the north-western margin of the great plateau of Central Asia.
