  2. Fineness modulus - Wikipedia

    en.wikipedia.org/wiki/Fineness_modulus

    The Fineness Modulus (FM) is an empirical figure obtained by adding the total percentage of the sample of an aggregate retained on each of a specified series of sieves, dividing the sum by 100. Sieves sizes are: 150-μm (No. 100), 300-μm (No. 50), 600-μm (No. 30), 1.18-mm (No. 16), 2.36-mm (No. 8), 4.75-mm (No. 4), 9.5-mm (3/8-in.), 19.0-mm ...

  3. Chvorinov's rule - Wikipedia

    en.wikipedia.org/wiki/Chvorinov's_rule

    Where the modulus M is the ratio of the casting's volume to its surface area: M = V A {\displaystyle M={\frac {V}{A}}} The mold constant B depends on the properties of the metal, such as density, heat capacity , heat of fusion and superheat, and the mold, such as initial temperature, density, thermal conductivity , heat capacity and wall thickness.

  4. Rule of mixtures - Wikipedia

    en.wikipedia.org/wiki/Rule_of_mixtures

    In materials science, a general rule of mixtures is a weighted mean used to predict various properties of a composite material . [1][2][3] It provides a theoretical upper- and lower-bound on properties such as the elastic modulus, ultimate tensile strength, thermal conductivity, and electrical conductivity. [3]

  5. 2.5D (machining) - Wikipedia

    en.wikipedia.org/wiki/2.5D_(machining)

    A 2.5D machine, also called a two-and-a-half-axis mill, possesses the capability to translate in all three axes but can perform the cutting operation only in two of the three axes at a time due to hardware or software limitations, or a machine that has a solenoid instead of a true, linear Z axis. A typical example involves an XY table that ...

  7. Geometric progression - Wikipedia

    en.wikipedia.org/wiki/Geometric_progression

    The first block is a unit block and the dashed line represents the infinite sum of the sequence, a number that it will forever approach but never touch: 2, 3/2, and 4/3 respectively. A geometric progression, also known as a geometric sequence, is a mathematical sequence of non-zero numbers where each term after the first is found by multiplying ...

  8. 2.5D integrated circuit - Wikipedia

    en.wikipedia.org/wiki/2.5D_integrated_circuit

    A 2.5D integrated circuit (2.5D IC) is an advanced packaging technique [1] that combines multiple integrated circuit dies in a single package [2] without stacking them into a three-dimensional integrated circuit (3D-IC) with through-silicon vias (TSVs). [3] The term "2.5D" originated when 3D-ICs with TSVs were quite new and still very difficult ...

  9. 2.5GBASE-T and 5GBASE-T - Wikipedia

    en.wikipedia.org/wiki/2.5GBASE-T_and_5GBASE-T

    The resulting standards are named 2.5GBASE-T and 5GBASE-T. [1][2][3] NBASE-T refers to Ethernet equipment that supports speeds of at least 2.5 Gbit/s and sometimes 5 or 10 Gbit/s, and that can automatically use training to operate at the best speed supported by the cable quality. [4] Usually it also supports additional link speeds (10, 100 or ...
