String

In a stair, an inclined board that supports the end of the steps; also called a stringer.

face string

An outer string, usually of better material or finish than the rough string which it covers; may be part of the actual construction or applied to the face of the supporting member.

outer string

The string at the outer and exposed edge of a stair, away from the wall.

String

 

(1) In vibration theory, a string is a thin, flexible, tightly stretched fiber whose density is uniformly distributed along its length. When the string is excited by, for example, being struck or plucked, it begins executing vibrational motions, in which all parts of the string are displaced in the transverse direction. Any vibration of a string can be represented as the sum of natural harmonic vibrations of the string. The frequencies f of these harmonic vibrations depend on the length l of the string, the cross-sectional area S, the tension Q, the density ρ of the string material, and the conditions of attachment of the ends of the string. For a string fastened to rigid supports, the frequency of the nth harmonic is

where n is a whole number. The displacement distribution at the initial moment—that is, the means by which the string is excited—determines the spectrum of the excited natural vibrations. A string is the simplest distributed-constant vibrational system and is often used to illustrate the oscillations of more complex mechanical, acoustic, and electrical systems.

(2) In music, a string is the source of sound vibrations in a number of musical instruments. The timbre of the sound of a string is determined by the vibrational mode of the string—that is, by the spectrum of the excited natural vibrations. In antiquity, strings were made from tree bark, plant fibers, and animal hairs (primarily horsehairs). In modern musical instruments, steel strings are used for the most part; gut strings, silk strings, and strings made from synthetic fibers (nylon) are used less often. To obtain low tones when the length of the string is limited, the string is made in the form of a thin fiber around which one or two layers of soft metal wire are wound.

Strings are also used in some electroacoustical devices.

What does it mean when you dream about string?

Dreaming about string often refers to something that needs to be secured or mended, particularly a relationship or some other situation. There are, however, many idiomatic expressions containing the word “string,” and a dream could be alluding to one of these meanings: “purse strings,” “to string someone along,” “first string,” “no strings attached,” “pull some strings,” etc.

string

[striŋ]

(computer science)

A set of consecutive, adjacent items of similar type; normally a bit string or a character string.

(engineering)

A piece of pipe, casing, or other down-hole drilling equipment coupled together and lowered into a borehole.

(geology)

A very small vein, either independent or occurring as a branch of a larger vein. Also known as stringer.

(mathematics)

One of the space curves that form a braid.

(mechanics)

A solid body whose length is many times as large as any of its cross-sectional dimensions, and which has no stiffness.

(particle physics)

A proposed structure for elementary particles, consisting of a one-dimensional curve with zero thickness and length typically of the order of the Planck length, 10^-35 m.

string

string, 1

1. In a stair, an inclined board which supports the end of the steps; also called a stringer.

2. In a lattice roof truss, a horizontal tie.

3. A stringcourse. Also called stringer, stringboard, or face string. For specific types, see closed string, face string, finish string, open string, outer string, rough string, stair string.

string

(programming)

A sequence of data values, usually bytes, which usually stand for characters (a "character string"). The mapping between values and characters is determined by the character set which is itself specified implcitly or explicitly by the environment in which the string is being interpreted.

The most common character set is ASCII but, since the late 1990s, there has been increased interest in larger character sets such as Unicode where each character is represented by more than eight bits.

Most programming languages consider strings (e.g. "124:shabooya:\n", "hello world") basically distinct from numbers which are typically stored in fixed-length binary or floating-point representation.

A bit string is a sequence of bits.

string

A set of contiguous alphanumeric characters. Strings are text, such as names, addresses and descriptions. Although a string may include numeric digits, the digits cannot be calculated within the string. They have to be copied out of the string into a numeric structure. Contrast with numeric data. See string literal and string handling.
