expansion

Definitions:

  • None
  • The act or process of expanding.
  • The state of being expanded.
  • None
  • An expanded part.
  • A product of expanding.
  • The extent or amount by which something has expanded.
  • None
  • A quantity written in an extended form, such as in a sum or product of terms.
  • The process of obtaining this form.
  • An expanse.
  • A period of increased economic or business activity.
  • The act of expanding.
  • The act of extending or distending, or of increasing in extent, size, bulk, amount, etc.
  • The state of being expanded; enlargement; distention; dilatation; increase of extent, size, bulk, amount, etc.
  • Specifically The increase in bulk of steam in the cylinder of an engine when its communication with the boiler is cut off, in which case its pressure on the piston retreating before it is in inverse ratio to the space it fills.
  • A part which constitutes an increase or in which the expanding occurs; specifically, in <em>entomology</em>, a flat projection of a margin, generally lateral: as, a frontal <em>expansion</em> covering the base of the antennæ.
  • Extension or spread of space; extent in general; hence, wide extent; immensity.
  • In <em>mathematics</em>, the development at length of an expression indicated in a contracted form, especially by means of the distributive principle.
  • In <em>ship-building</em>, a drawing in which a curved or warped surface, as a ship's outside plating or a longitudinal, is laid out or expanded on a plane surface by conventional methods to show approximately the true relations and dimensions of the parts.
  • The act of expanding or spreading out; the condition of being expanded; dilation; enlargement.
  • That which is expanded; expanse; extend surface.
  • Space through which anything is expanded; also, pure space.
  • an increase in the production of goods and services over time, and in the volume of business transactions, generally associated with an increase in employment and an increase in the money supply. Opposite of <contr>contraction</contr>.
  • The developed result of an indicated operation.
  • The operation of steam in a cylinder after its communication with the boiler has been cut off, by which it continues to exert pressure upon the moving piston.
  • The enlargement of the ship mathematically from a model or drawing to the full or building size, in the process of construction.
  • an enlarged or extended version of something, such as a writing or discourse.
  • an expansion joint. See below.
  • a curve the coördinates of which show the relation between the pressure and volume of expanding gas or vapor; esp. (Steam engine), that part of an indicator diagram which shows the declining pressure of the steam as it expands in the cylinder.
  • a cut-off gear. See <ex>Illust.</ex> of <er>Link motion</er>.
  • one that is regulated by the governor, and varies the supply of steam to the engine with the demand for power.
  • None
  • one that always operates at the same fixed point of the stroke.
  • None
  • a strip of compressible material placed at intervals between blocks of poured concrete, as in roads or sidewalks.
  • None
  • a cut-off valve, to shut off steam from the cylinder before the end of each stroke.
  • The act or process of <xref>expanding</xref>.
  • The fractional change in unit length per unit length per unit temperature change.
  • A new <xref>addition</xref>.
  • A product to be used with a previous product.
  • a discussion that provides additional information
  • the act of increasing (something) in size or volume or quantity or scope
  • a function expressed as a sum or product of terms
  • adding information or detail
