intermediate rib การใช้

• The cap frame was competed with the fitting of intermediate ribs and noggings.
• Small intermediate ribs are also sewn into the wing's trailing edge to improve stability.
• The tail fins were slightly shorter and the number of intermediate ribs was reduced to save weight and reduce stress on the trailing edge of the fin.
• These ribs are separated from each other by a shallow furrow, which becomes wider between the first two or three upper ribs, by the disappearance of the intermediate ribs.
• Member species are characterized by an essentially evolute shell in which the early whorls are smooth, with sinous radial or oblique constrictions but in which later whorls have feeble intermediate ribs on the outer part of the sides and venter.
• The immense size, however, of the square vault over the nave necessitated some additional support, so that an intermediate rib was thrown across the church, dividing the square compartment into six cells, and called the sexpartite vault; this was adopted in the cathedrals of Sens ( 1170 ), Laon ( 1195 ), Noyon ( 1190 ), Paris ( 1223 35 ), and Bourges ( 1250 ).
• Each course also was given a slight rise in the centre, so as to increase its strength; this enabled the French masons to dispense with the intermediate rib, which was not introduced by them until the 15th century, and then more as a decorative than a constructive feature, as the domical form given to the French web rendered unnecessary the ridge rib, which, with some few exceptions, exists only in England.
• At an early period, in consequence of the great span of the vault and the very slight rise or curvature of the web, it was thought better to simplify the construction of the web by introducing intermediate ribs between the wall rib and the diagonal rib and between the diagonal and the transverse ribs; and in order to meet the thrust of these intermediate ribs a ridge rib was required, and the prolongation of this rib to the wall rib hid the junction of the web at the summit, which was not always very sightly, and constituted the ridge rib.
