Manhole Cover
A manhole cover or maintenance hole cover is a removable plate forming the lid over the opening of a manhole, an opening large enough for a person to pass through that is used as an access point for an underground vault or pipe. It is designed to prevent anyone or anything from falling in, and to keep out unauthorized persons and material. Manhole covers date back at least to the era of ancient Rome, which had sewer grates made from stone. Description Manhole covers are often made out of cast iron, concrete or a combination of the two. This makes them inexpensive, strong, and heavy, usually weighing more than . The weight helps to keep them in place when traffic passes over them, and makes it difficult for unauthorized people without suitable tools to remove them. Manhole covers may also be made from glass-reinforced plastic or other composite material (especially in Europe, or where cover theft is of concern). Because of law restricting acceptable manual handling weights, Eu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dumpster
A dumpster is a movable waste container designed to be brought and taken away by a special collection vehicle, or to a bin that a specially designed garbage truck lifts, empties into its hopper, and lowers, on the spot. The word is a generic trademark of ''Dumpster'', an American brand name for a specific design. Generic usage of ''skip'' or ''skip bin'' is common in the UK, Australia and Ireland, as Dumpster is neither an established nor well-known brand in those countries. History The word "dumpster", first used commercially in 1936, came from the Dempster-Dumpster system of mechanically loading the contents of standardized containers onto garbage trucks, which was patented by Dempster Brothers in 1935. The containers were called ''Dumpsters'', a blending of the company's name with the word '' dump''. The Dempster Dumpmaster, which became the first successful front-loading garbage truck that used this system, popularized the word. The word ''dumpster'' has had at least three ...

Common Basilisk
The common basilisk (''Basiliscus basiliscus'') is a species of lizard in the family Corytophanidae. The species is endemic to Central America and South America, where it is found near rivers and streams in rainforests. It is also known as the Jesus Christ lizard, Jesus lizard, South American Jesus lizard, or ''legarto de Jesus Cristo'' for its ability to run on the surface of water. Description The common basilisk can be distinguished from similar species within its range by its large size and the high fin-like crest along its back. Most common basilisks are brown and cream in color. Males also have high crests on the head and tail. Both sexes are brown to olive, and have a white, cream, or yellow stripe on the upper lip and a second stripe along either side of the body; these stripes have higher contrast in juveniles and fade as the lizards age. Hatchlings weigh a mere and are long. Adults can grow to a total length (including tail) of 76 cm (2.5 feet). Females are gen ...

National Aeronautics And Space Administration
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management for ...

Methane
Methane ( , ) is a chemical compound with the chemical formula (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas. The relative abundance of methane on Earth makes it an economically attractive fuel, although capturing and storing it poses technical challenges due to its gaseous state under normal conditions for temperature and pressure. Naturally occurring methane is found both below ground and under the seafloor and is formed by both geological and biological processes. The largest reservoir of methane is under the seafloor in the form of methane clathrates. When methane reaches the surface and the atmosphere, it is known as atmospheric methane. The Earth's atmospheric methane concentration has increased by about 150% since 1750, and it accounts for 20% of the total radiative forcing from all of the long-lived and globally mixed greenhouse gases. It has also been detected on other plane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
416 Barrett
The .416 Barrett or 10.4×83mm centerfire rifle cartridge is a proprietary bottlenecked centrefire rifle cartridge designed in 2005. It is an alternative to the large-caliber .50 BMG in long-range high-power rifles. It was designed in response to a request for a medium/heavy rifle cartridge combination that was issued from Naval Surface Warfare Center Crane Division in late 2004. Design The Barrett .416 cartridge was designed by Chris Barrett, son of Ronnie Barrett, with the help of Pete Forras. The bullet was designed using some NACA low-supersonic-drag equations to design the shape. The cartridge was designed as an improvement to the .50 BMG cartridge, a common machine gun and rifle cartridge. It is a wildcatted .50 BMG case, shortened to from its original length of and necked down to accept a .416 caliber, projectile; however, the case dimensions are proprietary. Because the two cartridges, the .50 BMG and .416 Barrett, have identical base dimensions, all that is needed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armalite AR-50
The ArmaLite AR-50 is a .50 BMG, single-shot, bolt-action anti-materiel precision rifle manufactured by ArmaLite. Design The AR-50 rifle utilizes its weight and a large, fluted muzzle brake to reduce recoil. The AR-50 weighs approximately 34 pounds and is a single-shot bolt-action rifle. The barrel is thick and rigid to prevent it from flexing. All AR-50 barrels use 1:15 right hand rifling. The receiver features Armalite's octagonal design, strengthening the receiver against flexing. The receiver is bedded to the V-shaped stock, while the barrel is free-floated above the forend. The three-piece AR-50 stock is constructed from aluminum. It features an extruded forend and a skeleton butt stock with a removable and vertically adjustable butt plate. ArmaLite updated the rifle to the AR50-A1B model, which featured a smoother action and a more heavily-reinforced muzzle brake. The newer bolt stop could be depressed by hand to release the bolt. The AR50-A1B was designed for long-range sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kinetic Energy
In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest. Formally, a kinetic energy is any term in a system's Lagrangian which includes a derivative with respect to time. In classical mechanics, the kinetic energy of a non-rotating object of mass ''m'' traveling at a speed ''v'' is \fracmv^2. In relativistic mechanics, this is a good approximation only when ''v'' is much less than the speed of light. The standard unit of kinetic energy is the joule, while the English unit of kinetic energy is the foot-pound. History and etymology The adjective ''kinetic'' has its roots in the Greek word κίνησις ''kinesis'', m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
