# Cylinder vs. Prism

## Cylinder and Prism Definitions

#### Cylinder

The surface generated by a straight line intersecting and moving along a closed plane curve, the directrix, while remaining parallel to a fixed straight line that is not on or parallel to the plane of the directrix.

#### Prism

A solid figure whose bases or ends have the same size and shape and are parallel to one another, and each of whose sides is a parallelogram.

#### Cylinder

The portion of such a surface bounded by two parallel planes and the regions of the planes bounded by the surface.

#### Prism

A transparent body of this form, often of glass and usually with triangular ends, used for separating white light passed through it into a spectrum or for reflecting beams of light.

#### Cylinder

A solid bounded by two parallel planes and such a surface, especially such a surface having a circle as its directrix.

#### Prism

A cut-glass object, such as a pendant of a chandelier.

#### Cylinder

A cylindrical container or object.

#### Prism

A crystal form consisting of three or more similar faces parallel to a single axis.

#### Cylinder

The chamber in which a piston of a reciprocating engine moves.

#### Prism

A medium that misrepresents whatever is seen through it.

#### Cylinder

The chamber of a pump from which fluid is expelled by a piston.

#### Prism

(geometry) A polyhedron with parallel ends of the same size and shape, the other faces being parallelogram-shaped sides.

#### Cylinder

The rotating chamber of a revolver that holds the cartridges.

#### Prism

A transparent block in the shape of a prism (typically with triangular ends), used to split or reflect light.

#### Cylinder

Any of several rotating parts in a printing press, especially one that carries the paper.

#### Prism

A crystal in which the faces are parallel to the vertical axis.

#### Cylinder

(Archaeology)A cylindrical stone or clay object with an engraved design or inscription.

#### Prism

A solid whose bases or ends are any similar, equal, and parallel plane figures, and whose sides are parallelograms.

#### Cylinder

(geometry) A surface created by projecting a closed two-dimensional curve along an axis intersecting the plane of the curve. Category:en:Surfaces

When the two-dimensional curve is a circle, the cylinder is called a circular cylinder. When the axis is perpendicular to the plane of the curve, the cylinder is called a right cylinder. In non-mathematical usage, both right and circular are usually implied.

#### Prism

A transparent body, with usually three rectangular plane faces or sides, and two equal and parallel triangular ends or bases; - used in experiments on refraction, dispersion, etc.

#### Cylinder

(geometry) A solid figure bounded by a cylinder and two parallel planes intersecting the cylinder.

#### Prism

A polyhedron with two congruent and parallel faces (the bases) and whose lateral faces are parallelograms

#### Cylinder

Any object in the form of a circular cylinder.

#### Prism

Optical device having a triangular shape and made of glass or quartz; used to deviate a beam or invert an image

#### Cylinder

A cylindrical cavity or chamber in a mechanism, such as the counterpart to a piston found in a piston-driven engine.

#### Cylinder

(automotive) The space in which a piston travels inside a reciprocating engine or pump.

#### Cylinder

A container in the form of a cylinder with rounded ends for storing pressurized gas; a gas cylinder.

#### Cylinder

An early form of phonograph recording, made on a wax cylinder.

#### Cylinder

The part of a revolver that contains chambers for the cartridges.

#### Cylinder

(computing) The corresponding tracks on a vertical arrangement of disks in a disk drive considered as a unit of data capacity.

#### Cylinder

(transitive) To calender; to press (paper, etc.) between rollers to make it glossy.

#### Cylinder

A solid body which may be generated by the rotation of a parallelogram round one its sides; or a body of rollerlike form, of which the longitudinal section is oblong, and the cross section is circular.

#### Cylinder

Any hollow body of cylindrical form

#### Cylinder

The revolving square prism carrying the cards in a Jacquard loom.

#### Cylinder

A cylindrical container for oxygen or compressed air

#### Cylinder

A solid bounded by a cylindrical surface and two parallel planes (the bases)

#### Cylinder

A surface generated by rotating a parallel line around a fixed line

#### Cylinder
