cylinders

Definition of cylinders in English English dictionary: plural of cylinder
cylinder: An early form of phonograph recording, made on a wax cylinder
cylinder: A container in the form of a cylinder with rounded ends for storing pressurized gas
cylinder: A surface created by projecting a closed two-dimensional curve along an axis intersecting the plane of the curve
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.
cylinder: the part of a revolver that contains chambers for the cartridges
fire on all cylinders: To operate as effectively as possible
gas cylinders: plural form of gas cylinder
oxygen cylinders: plural form of oxygen cylinder
cylinder: {n} a long round body, roller, plaster, hollow
cylinder: (Otomotiv) A hollow tube-shaped pipe in the engine block. The piston rides up and down in the cylinder to compress the fuel/air mixture that drives the engine
cylinder: (n ) In a disk drive, the set of tracks with the same nominal distance from the axis about which the disk rotates See also sector
cylinder: A solid figure bounded by a cylinder and two parallel planes intersecting the cylinder
cylinder: The group of tracks, one on each platter surface, that is under the read and write heads of a disk drive during one rotation
cylinder: A gas cylinder is a cylinder-shaped container in which gas is kept under pressure. oxygen cylinders
cylinder: A three-dimensional figure with two congruent bases in parallel planes The bases are generally circular, but this need not be so Cylinders are a subclassification of cylindric solids, as are prisms (3-d figures with two polygonal bases in parallel planes) They may, or may not, be right cylinders (one circular base is directly above the other) If a cylinder is not right, it is oblique
cylinder: The set of tracks on a multi-headed disk that may be accessed without head movement In other words the tracks which are the same distance from the spindle about which the disk platters rotate Placing data that is more likely to be accessed at the same time on the same cylinder can reduce the access time significantly as moving the read-write heads is slow compared to the speed with which the disks rotate
cylinder: a chamber within which piston moves
cylinder: a surface generated by rotating a parallel line around a fixed line
cylinder: A three-dimensional object defined by an origin (that is, the center of the base) and three mutually perpendicular vectors that define the orientation and the major and minor radii of the cylinder Defined by the TQ3CylinderData data type
cylinder: {i} tube, tube-shaped figure; physical storage unit in a hard drive (Computers)
cylinder: A cylindrical hole or bore in the metal engine block The pistons go up and down inside the cylinder
cylinder: in general, a cylinder is the locus of (i e surface traced by) a straight line moving parallel to a fixed straight line and intersecting a fixed planar closed curve (the base); commonly, a right circular cylinder
cylinder: a set of matched tracks from storage disk surfaces
cylinder: The bore of a gun; the turning chambered breech of a revolver
cylinder: A chamber within an engine which contains a piston and valves An air/fuel mixture is introduced and then compressed by the piston, (this makes the air/fuel mixture much more combustible) next, a spark from the sparkplug is introduced igniting the mixture The force of this ignited mixture (a controlled explosion) forces the piston downward, creating the basic force of the engine (power stroke)
cylinder: When referring to disk drives, the number of different positions the disk drive's read/write heads can take over the unit's disk platters When viewed from above the platters, each head position describes an imaginary circle of different diameters on the platter's surface, but when viewed from the side, these circles can be thought of as a series of cylinders nested within each other, hence the term See also Geometry
cylinder: The space inclosed by any cylindrical surface
cylinder: An imaginary construct formed by joining comparably numbered tracks on the drive's magnetic platters -- a stack of vertically-aligned tracks at one actuator position (precisely the same on each platter) A cylinder represents one track on each platter; the number of is equal to the number of tracks
cylinder: A number of tracks located at the same radius on the several surfaces of a hard disk A hard disk with four platters has eight surfaces, so that at each position of the read-write heads, eight tracks can be read without head movement and these eight tracks form a cylinder
cylinder: and Cylinder Bore: The cylinder serves three important functions in an internal-combustion (IC) engine: 1) retains the piston and rings, and for this job must be precisely round and have a uniform diameter (for performance applications 0 0005-inch tolerance is considered the maximum allowable); 2) must have a surface finish that ensures both optimum ring seal (smooth and true) and yet provides adequate lubrication retention to ensure long life for both the piston and rings; and 3) the cylinder bore acts as a major structural element of the cylinder block, retaining the cylinder heads and the bottom end components The cylinder bore design, finish, and its preparation techniques are extremely important aspects of performance engine design
cylinder: a solid bounded by a cylindrical surface and two parallel planes (the bases)
cylinder: On a hard disk, a cylinder is all the tracks on all the disk platters that lie in the same relative position
cylinder: A portable cylindrical container used for the storage of a compressed gas
cylinder: A cylindrical cavity or chamber in a mechanism, such as the counterpart to a piston found in a piston-driven engine
cylinder: A cylinder is a solid with circular ends and straight sides A pipe is a cylinder The formula for the volume of a cylinder is: V = L R2 where R is the radius of the end of the cylinder and L is it's length
cylinder: a cylindrical container for oxygen or compressed air
cylinder: A hollow tube-shaped pipe in the engine block The piston rides up and down in the cylinder to compress the fuel/air mixture that drives the engine
cylinder: Any object in the form of a circular cylinder
cylinder: The drum of a revolver that contains the chambers for the ammunition
cylinder: Cylinders are the large round holes in the engine block in which combustion occurs This combustion forces the piston down and turns the crankshaft
cylinder: An area above the basket, outlined by the projection of the rim into space, where the ball cannot be touched by any player See goaltending
cylinder: the imaginary area directly above the basket where goaltending or basket interference can occur
cylinder: a cylindrical container for oxygen or compressed air a chamber within which piston moves a solid bounded by a cylindrical surface and two parallel planes (the bases) a surface generated by rotating a parallel line around a fixed line
cylinder: The space may be limited or unlimited in length
cylinder: The same track from each platter of a disk See also platter
cylinder: Any hollow body of cylindrical form The chamber of a steam engine in which the piston is moved by the force of steam
cylinder: The barrel of an air or other pump
cylinder: In an engine, a cylinder is a cylinder-shaped part in which a piston moves backwards and forwards. a 2.5 litre, four-cylinder engine
cylinder: The revolving platen or bed which produces the impression or carries the type in a cylinder press
cylinder: A vertically aligned set of tracks on a disk pack that are equidistant from the central spindle
cylinder: A cylinder is an object with flat circular ends and long straight sides. a cylinder of foam It was recorded on a wax cylinder
cylinder: As related to magnetic disks, a cylinder is a vertical column of tracks on a magnetic disk pack; since the read/write heads can read from any track on the cylinder without being moved in or out, storing multi-track files on cylinders is quite efficient Cylinder is also used as a unit of storage space On CMS, a one cylinder minidisk has storage for about 600K bytes
cylinder: The revolving square prism carrying the cards in a Jacquard loom
cylinder: In a right cylinder, the segment joining the centers of the circular bases is an altitude The length of an altitude is the height, h, of the cylinder A radius of a base is a radius, r, of the cylinder
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
