  2. Statically indeterminate - Wikipedia

    en.wikipedia.org/wiki/Statically_indeterminate

    A statically indeterminate structure can only be analyzed by including further information like material properties and deflections. Numerically, this can be achieved by using matrix structural analyses, finite element method (FEM) or the moment distribution method (Hardy Cross) .

  3. Indeterminate - Wikipedia

    en.wikipedia.org/wiki/Indeterminate

    Indeterminacy (philosophy), describing the shortcomings of definition in philosophy; Indeterminacy (music), music for which the composition or performance is determined by chance; Statically indeterminate, in statics, describing a structure for which the static equilibrium equations are insufficient for determining the internal forces

  4. Independent and identically distributed random variables

    en.wikipedia.org/wiki/Independent_and...

    In statistics, "random sample" is the typical terminology, but in probability, it is more common to say "IID." Identically distributed means that there are no overall trends — the distribution does not fluctuate and all items in the sample are taken from the same probability distribution.

  5. Indeterminate (variable) - Wikipedia

    en.wikipedia.org/wiki/Indeterminate_(variable)

    In mathematics, an indeterminate or formal variable is a variable (a symbol, usually a letter) that is used purely formally in a mathematical expression, but does not stand for any value. [ 1 ] [ 2 ] [ better source needed ]

  6. Moment distribution method - Wikipedia

    en.wikipedia.org/wiki/Moment_distribution_method

    The moment distribution method is a structural analysis method for statically indeterminate beams and frames developed by Hardy Cross. It was published in 1930 in an ASCE journal. [1] The method only accounts for flexural effects and ignores axial and shear effects.

  7. Direct stiffness method - Wikipedia

    en.wikipedia.org/wiki/Direct_stiffness_method

    In structural engineering, the direct stiffness method, also known as the matrix stiffness method, is a structural analysis technique particularly suited for computer-automated analysis of complex structures including the statically indeterminate type.

  8. Indeterminacy - Wikipedia

    en.wikipedia.org/wiki/Indeterminacy

    Indeterminate system; Aleatoric music and indeterminacy in music; Statically indeterminate; Underdetermined system; In set theory and game theory, the opposite of determinacy; In biology, indeterminate growth of an organism

  9. Undefined (mathematics) - Wikipedia

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

    The term undefined should be contrasted with the term indeterminate. In the first case, undefined generally indicates that a value or property can have no meaningful definition. In the second case, indeterminate generally indicates that a value or property can have many meaningful definitions.
