  2. Drill bit sizes - Wikipedia

    en.wikipedia.org/wiki/Drill_bit_sizes

    For Morse taper-shank drill bits, the standard continues in 1/64 inch increments up to 1¾ inch, then 1/32 inch increments up to 2¼ inch, 1/16 inch increments up to 3 inches, 1/8 inch increments up to 3¼ inches, and a single 1/4 inch increment to 3½ inches. One aspect of this method of sizing is that the size increment between drill bits ...

    en.wikipedia.org/wiki/National_pipe_thread

    The half-angle (between the taper surface and the axis of the pipe) is arctan(1 ⁄ 32) ≈ 1.7899° ≈ 1° 47′. The standard for Nominal Pipe Size (often abbreviated NPS, which should not be confused with the abbreviation NPS for the straight thread form standard) is loosely related to the inside diameter of Schedule 40 series of sizes.

  5. Time signature - Wikipedia

    en.wikipedia.org/wiki/Time_signature

    Most time signatures consist of two numerals, one stacked above the other: The lower numeral indicates the note value that the signature is counting. This number is always a power of 2 (unless the time signature is irrational), usually 2, 4 or 8, but less often 16 is also used, usually in Baroque music. 2 corresponds to the half note (minim), 4 to the quarter note (crotchet), 8 to the eighth ...

    The major diameter still extends to within ⁠ 1 / 8 ⁠ H of the theoretical sharp V, but the total depth of the thread is reduced 4% from ⁠ 5 / 8 ⁠ H = ⁠ 5 / 8 ⁠ cos(30°) P ≈ 0.541P to 0.52P. [5] This increases the amount of the theoretical sharp V which is cut off at the minor diameter by 10% from 0.25H to ⁠ 7 / 8 ⁠ − ⁠ 0. ...

    The #6-32 UNC screw has a thread pitch of 1/32 in (0.031250 inches (0.7938 mm)). The #6-32 UNC is a UTS screw specifying a major thread diameter of #6 which is defined as 0.1380 inches (3.51 mm); and 32 tpi (threads per inch) which equates to a thread pitch of 0.031250 inches (0.7938 mm). The optional UNC specification indicates the standard ...
