The standard designation for a UTS thread is a number indicating the nominal (major) diameter of the thread, followed by the pitch measured in threads per inch.For diameters smaller than 1 / 4 inch, the diameter is indicated by an integer number defined in the standard; for all other diameters, the inch figure is given.
[1] The greatest disadvantage is the difficulty in machining such a thread. The single-point cutting tools or taps and dies used to cut the thread cannot have efficient rake and relief angles (because of the square form), which makes the cutting slow and difficult.
Safety wire is commonly 0.5, 0.6, 0.8 or 1 mm (0.020, 0.025, 0.032 or 0.041 in) in diameter, but 0.5-and-1 mm (0.021-and-0.051 in) diameters are also available. It is usually made of stainless steel, but is also available in monel and inconel alloys for high temperature applications and copper for break-away applications. [7]
The ES for f is 10.33. The duration (4.5 work days) is added to the ES to get an EF of 14.83. The ES for g is 14.34. The duration (5.17 work days) is added to the ES to get an EF of 19.51. The ES for finish is the greatest EF of its predecessor activities (f and g). Since f has an EF of 14.83 and g has an EF of 19.51, the ES of finish is 19.51.
An IGES file is composed of 80-character ASCII records, a record length derived from the punched card era. Text strings are represented in "Hollerith" format, the number of characters in the string, followed by the letter "H", followed by the text string, e.g., "4HSLOT" (this is the text string format used in early versions of the Fortran language).
7-inch reel of 1 ⁄ 4-inch-wide (6.4 mm) recording tape, typical of non-professional use in the 1950s–70s. Studios generally used 10 1 ⁄ 2 inch reels on PET film backings. Inexpensive reel-to-reel tape recorders were widely used for voice recording in the home and in schools, along with dedicated models expressly made for business dictation.
Ideal test indicator pushed. Prior to modern geared dial mechanisms, test indicators using a single lever or systems of levers were common. The range and precision of these devices were generally inferior to modern dial type units, with a range of 10/1000 inch to 30/1000 inch, and precision of 1/1000 inch being typical.
8-inch floppy disk, inserted in drive, (3½-inch floppy diskette, in front, shown for scale) 3½-inch, high-density floppy diskettes with adhesive labels affixed The first commercial floppy disks, developed in the late 1960s, were 8 inches (203.2 mm) in diameter; [4] [5] they became commercially available in 1971 as a component of IBM products and both drives and disks were then sold ...
