If bounded by straight lines it is a rectilinearplane figure, if by curved lines it is a curvilinear plane figure.
Defn: A shallow sailboat with a rectilinear or V-shaped cross section.
Universal lever, a machine formed by a combination of a lever with the wheel and axle, in such a manner as to convert the reciprocating motion of the lever into a continued rectilinear motion of some body to which the power is applied.
A rapid-rectilinear lens will do very well if you are always assured of sunshine or bright clouds to supply exposure-light--and in such conditions even the lowly single-achromatic lens will suffice.
The same may be said as respects rectilinear direction, for many supposed that uniform motion can only take place in a circle.
Mr. Cecil Smith notes that the ornamentation covering the field of the design is partly rectilinear and geometrical, partly floral and of Mycenaean origin.
The undoubted symbolism of the cross in so many early coats of arms has been urged strongly by those who argue either for a symbolism for all these rectilinear figures or for an origin in articles of dress.
With reference to the origin of these ordinaries, by the use of which term is meant for the moment the rectilinear figures peculiar to armory, it may be worth the passing mention that the said origin is a matter of some mystery.
The cross, like the other heraldic rectilinear figures, came into existence, meaningless as a decoration for a shield, before armory as such existed, and probably before Christianity began.
This partition line may be employed for therectilinear charges known as "ordinaries" or "sub-ordinaries.
The twice-born look down upon the rectilinear consciousness of life of the once-born as being "mere morality," and not properly religion.
Stone and brick-work, in their rectilinear shapes, impose a rigidity in architectural design from which modern bricks, in their rich variety of flat and curved surfaces, have wrought emancipation.
A wave has to be suggested by stepped or broken lines, and so we have a rectilinear meander or fret, in contrast with its free-hand form as developed in a woven fabric.
Fire, air, earth, and water are bodies and therefore solids, and solids are contained in planes, and plane rectilinear figures are made up of triangles.
Hence the moon's deflection from the tangential or rectilinear path every minute comes out as very closely 16 feet (the true size of the earth being used).
This may be compared with the equation ofrectilinear motion of a particle, viz.
A shallow sailboat with a rectilinear or V-shaped cross section.
Deduct four miles for the distance from Hit to Pylæ, and we shall then have between Pylæ and Felujah, a rectilinear distance of forty-four miles.
They are long and rectilinear in outline and are not much affected by the magma.
The central space in the cove is soft and gravelly; but on both its sides it is flanked by low rocks, that stretch out into the sea in long rectilinear lines, like the foundations of dry-stone fences.
I showed the lens to Mr. Dallmeyer, and he thought he could make a better one; his Wide-Angle Rectilinear was the result.
In the ordinary engines the alternate expansion and condensation of steam imparts to a piston an alternating rectilinear motion, which is changed into a circular motion by means of various mechanical arrangements.
The lineage of the Thomomyini is essentially rectilinear and without the major branching seen in the tribe Geomyini.
Ulodendrons, with their rectilinear rows of circular scars, and their stems covered with leaf-like carvings, rivalled in effect the ornately relieved torus of a Corinthian column.
The circular or oval scars of this genus are probably impressions made by a rectilinear range of aerial roots placed on either side.
The endless scroll leads to rectilinear progression; the perpetually varied begets uniformity.
It would become merged in this spiral if the number of radii were infinite, for this would reduce the length of the rectilinear elements indefinitely and change this polygonal line into a curve.
The data presented in this article show that, while the earliest slide rules were of the circular type, the later slide rules of the seventeenth century were of the rectilinear type.
The fact that Oughtred had the mastery of the rectilinear slide rule as well, while Delamain in 1630 speaks only of the circular rule, weighs in Oughtred's favour.
It is a rectilinear rule, "of boxwood, well made, and bound together with brass at the two ends.
This Image was Oblong and not Oval, but terminated with two Rectilinear and Parallel Sides, and two Semicircular Ends.
When I had caused theRectilinear Sides AF, GM, [in Fig.
The Axis of the Spectrum PT, that is the Line drawn through the middle of it parallel to itsrectilinear Sides, did when produced pass exactly through the middle of that white round Image S.
Once the old skin has passed over the thick mid-body, the snake often crawls forward using rectilinear locomotion until the skin is completely shed.
Rectilinear locomotion is more useful to large, thick-bodied snakes which use this method of progression, chiefly when they are prowling and unhurried.
