  2. Lankford coefficient - Wikipedia

    However, in the actual press-working, the deep-drawability of steel sheets cannot be determined only by the value of and the measure of planar anisotropy, is more appropriate. In an ordinary cold rolled steel, R 90 {\displaystyle R_{90}} is the highest, and R 45 {\displaystyle R_{45}} is the lowest.

  3. R-value (insulation) - Wikipedia

    en.wikipedia.org/wiki/R-value_(insulation)

    The R-value is the building industry term [3] for thermal resistance "per unit area." [4] It is sometimes denoted RSI-value if the SI units are used. [5] An R-value can be given for a material (e.g., for polyethylene foam), or for an assembly of materials (e.g., a wall or a window). In the case of materials, it is often expressed in terms of R ...

    en.wikipedia.org/wiki/List_of_insulation_materials

    Typical R-values are given for various materials and structures as approximations based on the average of available figures and are sorted by lowest value. R-value at 1 m gives R-values normalised to a 1 metre (3 ft 3 in) thickness and sorts by median value of the range.

  5. Thermal conductance and resistance - Wikipedia

    en.wikipedia.org/wiki/Thermal_conductance_and...

    Thermal insulance (R-value) is a measure of a material's resistance to the heat current. It quantifies how effectively a material can resist the transfer of heat through conduction, convection, and radiation.

  6. Thermal conductivity and resistivity - Wikipedia

    en.wikipedia.org/wiki/Thermal_conductivity_and...

    The construction industry makes use of measures such as the R-value (resistance) and the U-value (transmittance or conductance). Although related to the thermal conductivity of a material used in an insulation product or assembly, R- and U-values are measured per unit area, and depend on the specified thickness of the product or assembly.

  7. Threaded rod - Wikipedia

    en.wikipedia.org/wiki/Threaded_rod

    Undercut studs have a shank equal to the pitch diameter of the screw thread. Undercut studs are designed to better distribute axial stresses. In a full-bodied stud the stresses are greater in the threads than in the shank. [5] Undercut studs (rolled thread) are also stronger because the metal is "rolled" up to the major diameter, not removed.

  9. Wall stud - Wikipedia

    en.wikipedia.org/wiki/Wall_stud

    Wall studs are framing components in timber or steel-framed walls, that run between the top and bottom plates.It is a fundamental element in frame building. The majority non-masonry buildings rely on wall studs, with wood being the most common and least-expensive material used for studs.
