Automatic Transmission
An automatic transmission (sometimes abbreviated to auto or AT) is a multi-speed transmission used in internal combustion engine-based motor vehicles that does not require any input from the driver to change forward gears under normal driving conditions. It typically includes a transmission, axle, and differential in one integrated assembly, thus technically becoming a transaxle. The most common type of automatic transmission is the hydraulic automatic, which uses a planetary gearset, hydraulic controls, and a torque converter. Other types of automatic transmissions include continuously variable transmissions (CVT), automated manual transmissions (AMT), and dual-clutch transmissions (DCT). An electronic automatic transmission (EAT) may also be called an electronically controlled transmission (ECT), or electronic automatic transaxle (EATX). A hydraulic automatic transmission may also colloquially called a " slushbox" or simply a "torque converter", although the latter term c ...

Mk 19 Grenade Launcher
The Mk 19 grenade launcher (pronounced Mark 19) is an American 40 mm belt-fed automatic grenade launcher that was first developed during the Vietnam War. Overview The Mk 19 is a belt-fed, blowback-operated, air-cooled, crew-served, fully-automatic weapon that is designed not to cook off. It fires 40 mm grenades at a cyclic rate of 325 to 375 rounds per minute, giving a practical rate of fire of 60 rounds per minute (rapid) and 40 rounds per minute (sustained). The weapon operates on the blowback principle, which uses the chamber pressure from each fired round to load and re-cock the weapon. The Mk 19 can launch its grenade at a maximum distance of , though its effective range to a point target is about , since the large rear leaf sight is only graduated as far. The nearest safe distance to launch the grenade is 310 meters in training and 75 meters in combat. Though the Mk 19 has a flash suppressor, it serves only to save the eyesight of its operat ...

M240
The M240 – officially the Machine Gun, 7.62 mm, M240 – is the U.S. military designation for the FN MAG, a family of belt-fed, gas-operated medium machine guns that chamber the 7.62×51mm NATO cartridge. The M240 has been used by the United States Armed Forces since the late 1970s. It is used extensively by infantry, most often in rifle companies, as well as on ground vehicles, watercraft and aircraft. Though it is heavier than some comparable weapons, it is highly regarded for reliability and its standardization among NATO members is a major advantage. All variants are fed from disintegrating belts and are capable of firing most types of 7.62 mm (.30/.308 cal) NATO ammunition. M240 variants can be converted to use non-disintegrating belts. There are significant differences in weight and some features among some versions which restrict the interchangeability of parts. The M240s used by the U.S. military are currently manufactured by FN America, the American ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Squad Automatic Weapon
A squad automatic weapon (SAW), also known as a section automatic weapon or light support weapon (LSW), is a man-portable automatic firearm attached to infantry squads or sections as a source of rapid direct firepower. Weapons fulfilling this role can be light machine guns, or modified selective-fire rifles fitted with a heavier barrel, bipod and a belt/drum-fed design. Squad automatic weapons usually fire the same cartridge (though heavier-bullet variants are preferred) as the assault rifles or battle rifles carried by other members of the unit. This reduces logistical requirements by making it only necessary to supply one type of service ammunition to a unit. These weapons are light enough to be carried and operated by one infantryman, unlike medium machine guns (such as the M1919 Browning) that require a crew to operate at full effectiveness; or heavy machine guns (such as the M2 Browning or the DShK) which fire more powerful cartridges but are also crew-served and typica ...

Running Boards
A running board or footboard is a narrow step fitted under the side doors of a tram ( cable car, trolley, or streetcar in North America), car, or truck. It aids entry, especially into high vehicles, and is typical of vintage trams and cars, which had much higher ground clearances than today's vehicles. It is also used as a fashion statement on vehicles that would not otherwise require it. The origin of the name running board is obscure; the first running boards predate automobiles and were installed on carriages as early as the 17th century. History Rail The term also applied to the walkways on top of railway/railroad boxcars. Originally, they were used by brakemen to travel from car to car to apply hand-operated brakes. With the adoption of the air brake this practice was abandoned. However the running board was still used as an observation point to pass hand signals to the train driver (train engineer in North America) when cars were being shunted (switched in No ...

Heater
Heating, ventilation, and air conditioning (HVAC) is the use of various technologies to control the temperature, humidity, and purity of the air in an enclosed space. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. "Refrigeration" is sometimes added to the field's abbreviation as HVAC&R or HVACR, or "ventilation" is dropped, as in HACR (as in the designation of HACR-rated circuit breakers). HVAC is an important part of residential structures such as single family homes, apartment buildings, hotels, and senior living facilities; medium to large industrial and office buildings such as skyscrapers and hospitals; vehicles such as cars, trains, airplanes, ships and submarines; and in marine environments, where safe and healthy building conditions are regulated with respect to temperature and humidity, using fresh ai ...

Air Conditioning
Air conditioning, often abbreviated as A/C or AC, is the process of removing heat from an enclosed space to achieve a more comfortable interior environment (sometimes referred to as 'comfort cooling') and in some cases also strictly controlling the humidity of internal air. Air conditioning can be achieved using a mechanical 'air conditioner' or alternatively a variety of other methods, including passive cooling or ventilative cooling. Air conditioning is a member of a family of systems and techniques that provide heating, ventilation, and air conditioning (HVAC). Heat pumps are similar in many ways to air conditioners, but use a reversing valve to allow them to both heat and also cool an enclosed space. Air conditioners, which typically use vapor-compression refrigeration, range in size from small units used within vehicles or single rooms to massive units that can cool large buildings. Air source heat pumps, which can be used for heating as well as cooling, are becoming incre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SWAT
In the United States, a SWAT team (special weapons and tactics, originally special weapons assault team) is a police tactical unit that uses specialized or military equipment and tactics. Although they were first created in the 1960s to handle riot control or violent confrontations with criminals, the number and usage of SWAT teams increased in the 1980s and 1990s during the War on Drugs and later in the aftermath of the September 11 attacks. In the United States by 2005, SWAT teams were deployed 50,000 times every year, almost 80% of the time to serve search warrants, most often for narcotics. By 2015 that number had increased to nearly 80,000 times a year. SWAT teams are increasingly equipped with military-type hardware and trained to deploy against threats of terrorism, for crowd control, hostage taking, and in situations beyond the capabilities of ordinary law enforcement, sometimes deemed "high-risk". SWAT units are often equipped with automatic and specialized fir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Counter Terrorism
Counterterrorism (also spelled counter-terrorism), also known as anti-terrorism, incorporates the practices, military tactics, techniques, and strategies that governments, law enforcement, business, and intelligence agencies use to combat or eliminate terrorism. Counterterrorism strategies are a government's motivation to use the instruments of national power to defeat terrorists, the organizations they maintain, and the networks they contain. If definitions of terrorism are part of a broader insurgency, counterterrorism may employ counterinsurgency measures. The United States Armed Forces uses the term foreign internal defense for programs that support other countries' attempts to suppress insurgency, lawlessness, or subversion, or to reduce the conditions under which threats to national security may develop. History The first counter-terrorism body formed was the Special Irish Branch of the Metropolitan Police, later renamed the Special Branch after it expanded its sc ...

Power Steering
A power steering is a mechanical device equipped on a motor vehicle that helps drivers steer the vehicle by reducing steering effort needed to turn the steering wheel, making it easier for the vehicle to turn or maneuver at lower speeds. Hydraulic or electric actuators add controlled energy to the steering mechanism, so the driver can provide less effort to turn the steered wheels when driving at typical speeds, and reduce considerably the physical effort necessary to turn the wheels when a vehicle is stopped or moving slowly. Power steering can also be engineered to provide some artificial feedback of forces acting on the steered wheels. Hydraulic power steering systems for cars augment steering effort via an actuator, a hydraulic cylinder that is part of a servo system. These systems have a direct mechanical connection between the steering wheel and the linkage that steers the wheels. This means that power-steering system failure (to augment effort) still permits the vehicle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
