Given a diagram F : J → C, a cone comprises of an object N of C, together with a household of morphisms ψX : N → F(X) listed by every one of the objects of J, so that for each and every morphism f : X → Y in J, . After that N may be the vertex of this cone, whose sides are typical the ψX listed by Ob(J) and whoever base is F. The cone is reported to be "from N to F" and certainly will be denoted as (N, ψ).
A solid regarding the type described because of the transformation of a right-angled triangle about one of many sides right beside the best direction; -- labeled as in addition a right cone. Much more usually, any solid having a vertical point and bounded by a surface that is explained by a straight line always moving during that vertical point; a great having a circle because of its base and tapering to a place or vertex.
Everything formed pretty much like a mathematical cone.
The fresh fruit or strobile for the Coniferæ, as of the pine, fir, cedar, and cypress. It's composed of woody scales, every one of which includes one or two seeds at its base.
A shell for the genus Conus, having a conical type.
In geometry: a good generated by the change of a right-angled triangle upon one of its edges as an axis.
A solid the surface which comes with a circle, which types its base, therefore the envelop of all the minimal right outlines which get in on the circumference regarding the circle to a fixed point lying with no perpendicular into group from its center: particularly termed an oblique or scalene cone. See conic.
In modern-day geom., any surface produced by a line one point by which is fixed.
such a thing shaped like a cone.
In anat.: The conarium, or pineal human body associated with the brain.
One of the moment cone-shaped frameworks forming with all the alleged “rods” a layer associated with the retina. See retina.
In conchology, a shell of the family Conidoe, described as its obconic form.
The hill surrounding the crater of a volcano, formed because of the steady accumulation associated with ejected material.

a couple of equal cones with parallel axes, however with the little base of 1 based on the large base of the various other, at such a distance that an endless gear on their areas or an idle transmitting-wheel between them can transfer energy from to another. Either in kind these devices enable you to send a varying velocity proportion by modifying belt or wheel so that a large circumference of driver is opposite a tiny circumference of motorist, or perhaps the reverse.
