If bending, it has a perfect conical surface on its side.

Sometimes the term "conical surface" is used to mean just one nappe.

An axicon is a specialized type of lens which has a conical surface.

Not to be confused with the conical surface.

Further, a conical surface is invariant as a set under a homothety of space.

At the top, The Shadow rested upon the conical surface of the turret roof.

Both of these surfaces asymptote to the same conical surface as x or y become large:

Red sparks chased themselves over Thea's conical surface.

Indeed, in projective geometry a cylindrical surface is just a special case of a conical surface.

In general, a conical surface consists of two congruent unbounded halves joined by the apex.

It is a conical prism and determines the inclination angle of conical surface.

The crushed ore, suspended in water was introduced onto a central cone and spread outwards over a slightly inclined conical surface.

A cylindrical surface can be viewed as a limiting case of a conical surface whose apex is moved off to infinity in a particular direction.

Instead of a conical surface, one requires conical hypersurfaces in four-dimensional space with points determined by quadratic forms.

It is a quadric surface, and is one of the possible 3-manifolds which are 4-dimensional equivalents of the conical surface in 3 dimensions.

However, instead of mating two spinning disks, the cone clutch uses two conical surfaces to transmit torque by friction.

Other examples are a conical surface with elliptical directrix, the right conoid, the helicoid, and the tangent developable of a smooth curve in space.

A hyperbola may be defined as the curve of intersection between a right circular conical surface and a plane that cuts through both halves of the cone.

(In some cases, however, the two nappes may intersect, or even coincide with the full surface.) Sometimes the term "conical surface" is used to mean just one nappe.

The boost protective cover, which was attached to the launch escape system, protected the conical surface of the command module and remained intact through a canard-induced pitch maneuver.

The spherical cone consists of two unbounded nappes, which meet at the origin and are the analogues of the nappes of the 3-dimensional conical surface.

In mathematics, a conic section (or just conic) is a curve obtained as the intersection of a cone (more precisely, a right circular conical surface) with a plane.

The boundary of an infinite or doubly infinite cone is a conical surface, and the intersection of a plane with this surface is a conic section.

He suggests that partially developed conical surfaces are also possible as a result of pressure developed from overlying sediments under conditions where a unilateral release of horizontal pressure may become effective.

In the special case that R is a single point, S is a plane, and A is a conic section on S, the projective cone is a conical surface; hence the name.
