  2. Standard form contract - Wikipedia

    en.wikipedia.org/wiki/Standard_form_contract

    A standard form contract (sometimes referred to as a contract of adhesion, a leonine contract, [a] a take-it-or-leave-it contract, or a boilerplate contract) is a contract between two parties, where the terms and conditions of the contract are set by one of the parties, and the other party has little or no ability to negotiate more favorable terms and is thus placed in a "take it or leave it ...

  3. Material selection - Wikipedia

    en.wikipedia.org/wiki/Material_selection

    For the example of the stiff/light part discussed above would have Young's modulus on one axis and density on the other axis, with one data point on the graph for each candidate material. On such a plot, it is easy to find not only the material with the highest stiffness, or that with the lowest density, but that with the best ratio E / ρ ...

  5. Structural engineering theory - Wikipedia

    en.wikipedia.org/wiki/Structural_engineering_theory

    Stiffness depends upon material properties and geometry. The stiffness of a structural element of a given material is the product of the material's Young's modulus and the element's second moment of area. Stiffness is measured in force per unit length (newtons per millimetre or N/mm), and is equivalent to the 'force constant' in Hooke's Law.

  6. Specific modulus - Wikipedia

    en.wikipedia.org/wiki/Specific_modulus

    Approximate specific stiffness for various materials. No attempt is made to correct for materials whose stiffness varies with their density. Material Young's modulus Density (g/cm 3) Young's modulus per density; specific stiffness (10 6 m 2 s −2) Young's modulus per density squared (10 3 m 5 kg −1 s −2) Young's modulus per density cubed ...

    Static pressure of fluid if all kinetic energy were converted into pressure. Template documentation This template's documentation is missing, inadequate, or does not accurately describe its functionality or the parameters in its code.

  8. Sandwich theory - Wikipedia

    en.wikipedia.org/wiki/Sandwich_theory

    The composite has a considerably higher shear stiffness to weight ratio than an equivalent beam made of only the core material or the facesheet material. The composite also has a high tensile strength to weight ratio. The high stiffness of the facesheet leads to a high bending stiffness to weight ratio for the composite.

  9. Persistence length - Wikipedia

    en.wikipedia.org/wiki/Persistence_length

    If you plot out how correlated the tangent angles at two different points are as a function of the distance between the two points, you'll get a plot that starts out at 1 (perfect correlation) at a distance of zero and drops exponentially as distance increases. The persistence length is the characteristic length scale of that exponential decay.
