Making Out
Making out is a term of American English, American origin dating back to at least 1949, and is used to refer to kissing, including extended French kissing or ''necking'' (heavy kissing of the neck, and above), or to acts of non-penetrative sex such as heavy petting ("intimate contact, just short of sexual intercourse"). Equivalent terms in other dialects include the British English getting off and the Hiberno-English shifting. When performed in a stationary vehicle, it has been euphemistically referred to as ''parking'', coinciding with American car culture. History The sexual connotations of the phrase "make out" appear to have developed in the 1930s and 1940s from the phrase's other meaning: "to succeed". Originally, it meant "to seduce" or "to have sexual intercourse". "Petting" ("making out" or foreplay) was popularized in the 1920s, as youth culture challenged earlier Victorian era strictures on sexuality with the rise in popularity of "petting parties". At these par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Necking (engineering)
In engineering and materials science, necking is a mode of tensile Deformation (engineering), deformation where relatively large amounts of Deformation (mechanics), strain localize disproportionately in a small region of the material. The resulting prominent decrease in local cross-sectional area provides the basis for the name "neck". Because the local strains in the neck are large, necking is often closely associated with Yield (engineering), yielding, a form of Plasticity (physics), plastic deformation associated with ductile materials, often metals or polymers. Once necking has begun, the neck becomes the exclusive location of yielding in the material, as the reduced area gives the neck the largest local Stress (mechanics), stress. Formation Necking results from an instability during tensile deformation when the cross-sectional area of the sample decreases by a greater proportion than the material Strain hardening, strain hardens. :fr:Armand Consid%C3%A8re, Armand Considè ...

Necking (electronics)
A teardrop is typically drop-shaped feature on a printed circuit board and can be found on the junction of vias or contact pads. Purpose The main purpose of teardrops is to enhance structural integrity in presence of thermal or mechanical stresses, for example due to vibration or flexing. Structural integrity may be compromised, e.g., by misalignment during drilling, so that too much copper may be removed by the drill hole in the area where a trace connects to the pad or via. An extra advantage is the enlarging of manufacturing tolerances, making manufacturing easier and cheaper. Shape While a typical shape of a teardrop is straight-line tapering, they may be concave. This type of teardrop is also called ''filleting'' or ''straight''. To produce a ''snowman''-shaped teardrop, a secondary pad of smaller size is added at the junction overlapping with the primary pad (hence the nickname). Necking For similar reasons, a technique called ''trace necking'' reduces (or ''neck ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Giraffe
The giraffe is a large Fauna of Africa, African even-toed ungulate, hoofed mammal belonging to the genus ''Giraffa.'' It is the Largest mammals#Even-toed Ungulates (Artiodactyla), tallest living terrestrial animal and the largest ruminant on Earth. It is classified under the Family (biology), family Giraffidae, along with its closest extant relative, the okapi. Traditionally, giraffes have been thought of as one species, ''Giraffa camelopardalis'', with nine subspecies. Most recently, researchers proposed dividing them into four Neontology#Extant taxa versus extinct taxa, extant species which can be distinguished by their fur Animal coat, coat patterns. Six valid Lists of extinct species, extinct species of ''Giraffa'' are known from the fossil record. The giraffe's distinguishing characteristics are its extremely long neck and legs, horn-like ossicones, and spotted coat patterns. Its scattered range extends from Chad in the north to South Africa in the south and from Niger in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wildcat Cartridge
A wildcat cartridge, often shortened to wildcat, is a custom-made cartridge (weaponry), cartridge for which ammunition and/or firearms are not mass-produced. These cartridges are often created as experimental variants to optimize a certain ballistic performance characteristic (such as the power, size, or efficiency) of an existing commercial cartridge, or may merely be intended as novelty items. Developing and using wildcat cartridges does not generally serve a purpose in military or law enforcement; it is more a hobby for serious sport shooting, hunting, gunsmithing and handloading enthusiasts, particularly in the United States. There are potentially endless varieties of wildcat cartridge: one source of gunsmithing equipment has a library of over 6,000 different wildcat cartridges for which they produce equipment such as chamber reamers. Development of a wildcat Often, wildcats are commercially sold rounds that have been modified in some way to alter the cartridge's performance. ...

MG 151 Cannon
The ''Maschinengewehr'' (MG) 151 is a belt-fed autocannon for aircraft use, developed in Nazi Germany from 1934 to 1940 and produced by Waffenfabrik Mauser during World War II. It was originally produced in 15.1 mm caliber from 1940, with a 15×96mm cartridge, but due to demand for higher effect against aircraft, especially with the introduction of mine shells for the 20 mm MG-FF/M aircraft cannon, the design was rechambered to 20 mm caliber in 1941, using a newly developed 20×82mm cartridge which traded projectile velocity for explosive power. The initial 15 mm variant then became known as the MG 151/15, with the new 20 mm variant becoming the MG 151/20. The MG 151/20 cannon was widely used on German Luftwaffe combat aircraft throughout World War II, mainly as offensive armament, but also seeing some use as defensive guns. Existing MG 151/15 guns saw use as aircraft armament throughout the war, albeit more limited compared to the MG 151/20, but also as ...

M61 Vulcan
The M61 Vulcan is a Hydraulic machinery, hydraulically, electrically, or pneumatics, pneumatically driven, six-Gun barrel, barrel, air-cooled, electrically fired Gatling gun, Gatling-style rotary cannon which fires 20 mm caliber, rounds at an extremely high rate (typically 6,000 rounds per minute). The M61 and its derivatives have been the principal cannon armament of United States Armed Forces, United States military fixed-wing aircraft for over sixty years. The M61 was originally produced by General Electric. After several mergers and acquisitions, it is produced by General Dynamics . It is also manufactured under license in Japan by Sumitomo Heavy Industries for Japan's Japan Self-Defense Force, Self-Defense Force and by SNT Dynamics in South Korea. Multiple-barrel firearms Development At the end of World War II, the United States Army Air Forces began to consider new directions for future military aircraft guns.
