  4. Specific strength - Wikipedia

    en.wikipedia.org/wiki/Specific_strength

    The data of this table is from best cases, and has been established for giving a rough figure. Note: Multiwalled carbon nanotubes have the highest tensile strength of any material yet measured, with labs producing them at a tensile strength of 63 GPa, [ 36 ] still well below their theoretical limit of 300 GPa.

  5. Bar (unit) - Wikipedia

    en.wikipedia.org/wiki/Bar_(unit)

    The kilobar, equivalent to 100 MPa, is commonly used in geological systems, particularly in experimental petrology. The abbreviations "bar(a)" and "bara" are sometimes used to indicate absolute pressures, and "bar(g)" and "barg" for gauge pressures. The usage is deprecated but still prevails in the oil industry (often by capitalized "BarG" and ...

    In the second example, REVOKE removes User1's privileges to use the INSERT command on the table Employees. DENY is a specific command. We can conclude that every user has a list of privilege which is denied or granted so command DENY is there to explicitly ban you some privileges on the database objects.:

  7. Stress intensity factor - Wikipedia

    en.wikipedia.org/wiki/Stress_intensity_factor

    Polar coordinates at the crack tip. In fracture mechanics, the stress intensity factor (K) is used to predict the stress state ("stress intensity") near the tip of a crack or notch caused by a remote load or residual stresses. [1]

  8. List of viscosities - Wikipedia

    en.wikipedia.org/wiki/List_of_viscosities

    For dynamic viscosity, the SI unit is Pascal-second. In engineering, the unit is usually Poise or centiPoise, with 1 Poise = 0.1 Pascal-second, and 1 centiPoise = 0.01 Poise.

  9. Ultimate tensile strength - Wikipedia

    en.wikipedia.org/wiki/Ultimate_tensile_strength

    The ultimate tensile strength of a material is an intensive property; therefore its value does not depend on the size of the test specimen.However, depending on the material, it may be dependent on other factors, such as the preparation of the specimen, the presence or otherwise of surface defects, and the temperature of the test environment and material.
