  2. Support (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Support_(mathematics)

    In mathematics, the support of a real-valued function is the subset of the function domain containing the elements which are not mapped to zero. If the domain of is a topological space, then the support of is instead defined as the smallest closed set containing all points not mapped to zero. This concept is used widely in mathematical analysis .

  3. Structural support - Wikipedia

    en.wikipedia.org/wiki/Structural_support

    Structural support. A structural support is a part of a building or structure that provides the necessary stiffness and strength in order to resist the internal forces (vertical forces of gravity and lateral forces due to wind and earthquakes) and guide them safely to the ground. External loads (actions of other bodies) that act on buildings ...

  4. Social support - Wikipedia

    en.wikipedia.org/wiki/Social_support

    Social support. Social support is the perception and actuality that one is cared for, has assistance available from other people, and most popularly, that one is part of a supportive social network. These supportive resources can be emotional (e.g., nurturance), informational (e.g., advice), or companionship (e.g., sense of belonging); tangible ...

    Catalyst support. In the Phillips catalyst, used for about half of the industrial production of polyethylene, the chromium catalyst is supported on silica. In chemistry, a catalyst support is a material, usually a solid with a high surface area, to which a catalyst is affixed. [1] The activity of heterogeneous catalysts is mainly promoted by ...

    Support and resistance. In stock market technical analysis, support and resistance are certain predetermined levels of the price of a security at which it is thought that the price will tend to stop and reverse. [1] These levels are denoted by multiple touches of price without a breakthrough of the level.

  8. Span (engineering) - Wikipedia

    en.wikipedia.org/wiki/Span_(engineering)

    In engineering, span is the distance between two adjacent structural supports (e.g., two piers) of a structural member (e.g., a beam ). Span is measured in the horizontal direction either between the faces of the supports ( clear span) or between the centers of the bearing surfaces ( effective span ): [1] A span can be closed by a solid beam or ...

  9. Conjugate beam method - Wikipedia

    en.wikipedia.org/wiki/Conjugate_beam_method

    Conjugate beam method. The conjugate-beam methods is an engineering method to derive the slope and displacement of a beam. A conjugate beam is defined as an imaginary beam with the same dimensions (length) as that of the original beam but load at any point on the conjugate beam is equal to the bending moment at that point divided by EI.
