The frame of the rigid hull is built of sixteen longitudinals or girders of trellised or latticed metal; it runs the whole length of the airship and is riveted at regular intervals to cross-sections of latticed girders.
The main hull is thus divided into a number of compartments, each separated from one another by means of these latticed radial discs or wheel-like structures and otherwise enclosed by the sixteen latticed girder longitudinals or beams.
These longitudinals and the skids end at the leading edge of the back plane and the laminated skids and wheels are placed there.
Under the two rigid T-section longitudinals there are a number of elastic laminated wood springs set at an angle, and the lower ends of these are pivoted on to a long elastic skid.
A sufficient number of uprights fill the space between the plane and the two T-section longitudinals which form the rigid bottom of the machine.
The whole of the back plane is now supported by two curved members, which start from the girder of the leading edge and curve down to the T-section longitudinals which form the rigid part of the chassis.
Sleepers and longitudinals are replaced by 1/2-inch boards, 8 inches wide.
Fix the sleepers on the longitudinals before hammering the rails into the slots.
The compressive resistance which would have been produced by the imaginary longitudinals at the elastic limit of the hooping metal, the volume of the imaginary longitudinals being taken as 2.
Two battens on each side were employed with the usual six longitudinalsin the bottom frame.
Whereas the Kodiak kayak has eleven battens (including the keelson) in its frame, the Nunivak kayak has nine, and all the longitudinals in it are rectangular in section.
In some bateau variations of the kayak-form canoe, the longitudinals were secured by crosspieces, the ends of which were tenoned into the inside faces of the chine battens.
The multi-chine types of the western Arctic have from seven to eleven longitudinals (including the keelson) in addition to the gunwales.
Another is to be seen in an old model of an extinct Athabascan kayak form, which has only four longitudinals and chine members that are very wide and rounded only on the outboard face.
The crosspieces, five in all, were fastened to the longitudinals with thongs passing through holes in the ends.
The width amidships of the bottom framework of loose longitudinals was 13 inches.
Next the longitudinals are fitted and, finally, the remaining transverse frames are put in place.
The stem head was commonly bent sharply and secured between the gunwale ends at the point where the two longitudinals were fastened together, much as in some Ojibway long-nose canoes.
One model of the extinct British Columbia bateau form, for example, showed but three longitudinalsin the bottom, though the probable size of the canoe undoubtedly would have required a greater number.
But in the Mackenzie form of canoe, the longitudinals had no cross-members and, like the side battens, were held in place by the pressure of the sprung ribs against the bark cover.
The ends of the four inner longitudinals were cut off on the snye to bear on the inside face of the chine battens (in some instances they were cut short of this).
The bow piece is carved from a block, and the longitudinals are lashed to it, each in a carefully fitted notch.
Thus, in the lower Yukon Valley in Alaska the bottom frame of the canoes built there was a rigidly constructed unit, even though the side longitudinals were held in place by rib pressure alone.
This will be accompanied by stressing of the connections, and a transfer to the longitudinals of as much of the tensile stress properly belonging to the booms as the stiffness of the cross-girders may communicate.
For small longitudinals it is, perhaps, sufficient to use end angles with very broad flanges against the cross-girder web; these to be riveted in the manner indicated in Fig.
It would appear that light pressed troughs running across the longitudinals would, by yielding in every section, also furnish relief, as compared with the rigidity of flat plates.
Cross-girders and longitudinals also may have loose rivets at their connections, and be very badly wasted, with quite possibly cracks in the webs, or other defects already enlarged upon.
The reinforcement is of the same form for all sizes of pipe, but seven longitudinals were used in the 72-in.
The arch reinforcing bars were then bolted to the anchor bars and the longitudinals connected up.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "longitudinals" in a variety of sentences. We hope that you will now be able to make sentences using this word.
