Manhole Cover
A manhole 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, Europe has seen a move towar ... [...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 ''wheelie bin'' may be used in other English speaking 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 trademarks associated with it by Dempster Brothers, but today it is often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rupture Disk
A rupture disc, also known as a pressure safety disc, burst disc, bursting disc, or burst diaphragm, is a non-reclosing pressure relief safety device that, in most uses, protects a pressure vessel, equipment or system from overpressurization or potentially damaging vacuum conditions. A rupture disc is a type of sefe device because it has a one-time-use membrane that fails at a predetermined differential pressure, either positive or vacuum and at a coincident temperature. The membrane is usually made out of metal, but nearly any material (or different materials in layers) can be used to suit a particular application. Rupture discs provide instant response (within milliseconds or microseconds in very small sizes) to an increase or decrease in system pressure, but once the disc has ruptured it will not reseal. Major advantages of the application of rupture discs compared to using pressure relief valves include leak-tightness, cost, response time, size constraints, flow area, and ...

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 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 genders 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 generally , and weigh half ...

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 abundance of methane on Earth makes it an economically attractive fuel, although capturing and storing it is difficult because it is a gas at standard temperature and pressure. In the Earth's atmosphere methane is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. Methane is an Organic chemistry, organic Organic compound, compound, and among the simplest of organic compounds. Methane is also a hydrocarbon. 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 of Earth, atmosphere, it is known as atmospheric methane. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
416 Barrett
The .416 Barrett (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 need ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kinetic Energy
In physics, the kinetic energy of an object is the form of energy that it possesses due to its motion. In classical mechanics, the kinetic energy of a non-rotating object of mass ''m'' traveling at a speed ''v'' is \fracmv^2.Resnick, Robert and Halliday, David (1960) ''Physics'', Section 7-5, Wiley International Edition The kinetic energy of an object is equal to the work, or force ( F) in the direction of motion times its displacement ( s), needed to accelerate the object from rest to its given speed. The same amount of work is done by the object when decelerating from its current speed to a state of rest. The SI unit of energy is the joule, while the English unit of energy is the foot-pound. In relativistic mechanics, \fracmv^2 is a good approximation of kinetic energy only when ''v'' is much less than the speed of light. History and etymology The adjective ''kinetic'' has its roots in the Greek word κίνησις ''kinesis'', meaning "motion". The dichoto ...
