Bullet Sorojini
A bullet is a kinetic projectile, a component of firearm ammunition that is shot from a gun barrel. They are made of a variety of materials, such as copper, lead, steel, polymer, rubber and even wax; and are made in various shapes and constructions (depending on the intended applications), including specialized functions such as hunting, target shooting, training, and combat. Bullets are often tapered, making them more aerodynamic. Bullet size is expressed by weight and diameter (referred to as "caliber") in both imperial and metric measurement systems. Bullets do not normally contain explosives but strike or damage the intended target by transferring kinetic energy upon impact and penetration. Description The term ''bullet'' is from Early French, originating as the diminutive of the word ''boulle'' (''boullet''), which means "small ball". Bullets are available singly (as in muzzle-loading and cap and ball firearms) but are more often packaged with propellant as a cartridge ( ...

GP11 Coupe
The EMD GP11 is a four-axle diesel locomotive rebuilt by the Illinois Central Railroad's Paducah, Kentucky, Paducah shops. It is very similar in appearance to the GP8 and GP10. The Illinois Central Railroad began its GP11 rebuilding program in 1978. All units were rebuilt from recycled EMD GP7, EMD GP9, GP9 or EMD GP18, GP18 parts. Spotting features are an angled cab, exterior paper air filter, new air intake for the traction motors and four exhaust stacks. Internally they had EMD Dash 2, Dash 2 solid state electrical equipment. Original buyers A total of 54 of these remanufactured locomotives were built from April 1978 to 1981. The first prototype unit of this model was numbered 8301. To avoid confusion the 8700-series was created to separate the GP11s from the GP10s. It was intended that 8301 would be renumbered 8700 but that never happened. IC units 8701 through 8726 were built in 1979 while units 8727 through 8750 were built in 1980; the remaining three from 8751 to 8753 we ...

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 ...

Automatic Firearm
An automatic firearm or fully automatic firearm (to avoid confusion with semi-automatic firearms) is a self-loading firearm that continuously Chamber (firearms), chambers and fires Cartridge (firearms), rounds when the trigger (firearms), trigger mechanism is actuated. The action (firearms), action of an automatic firearm is capable of harvesting the excess energy released from a previous discharge to feed a new ammunition cartridge (firearms), round into the chamber (firearms), chamber, and then igniting the propellant and discharging the projectile (either bullet, shot (pellet), shot, or shotgun slug, slug) by delivering a hammer (firearms), hammer or firing pin, striker impact on the primer (firearms), primer. If ''both'' the feeding and ignition procedures are automatically cycled, the weapon will be considered "fully automatic" and will fire continuously as long as the trigger is kept depressed and the ammunition feeding (either from a magazine (firearms), magazine or a belt ...

Belt (firearms)
An ammunition belt is a firearm device used to package and feed cartridge (firearms), cartridges, typically for rapid-firing automatic weapons such as machine guns. Belt-fed systems minimize the proportional weight of the ammunition apparatus to the entire weapon system, and allow high rates of continuous fire without needing frequent magazine (firearms), magazine changes. The capacity of belts and associated #Container device, belt containers is typically a function of weight and bulk, and their size is limited by caliber and the combined portability of the weapon and ammunition. Typical capacities for man-portable weapon systems range from 50 to 300 rounds of ammunition. Variants Feed strip The "feed strip" (also referred to as an "ammo strip" or "feed tray") was initially designed in 1895, based on initial designs by Captain Baron Adolf Odkolek von Ujezda of Vienna, Austria. A feed strip is a simple rigid metal (usually steel or brass) tray, typically holding 15 to 30 c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clip (firearms)
A clip is a device that is used to store multiple rounds of ammunition together as a unit for insertion into the Magazine (firearms), magazine or Cylinder (firearms), cylinder of a firearm. This speeds up the process by loading the firearm with multiple rounds simultaneously, rather than individually, as with loose rounds of ammunition. There are several types, most made of inexpensive Stamped metal, stamped sheet metal, generally they are intended to be disposable, but they are more often retained and reused. Types Stripper A stripper clip (American English) or charger clip (Commonwealth English) is a speedloader that holds several pistol or rifle cartridges as a unit for easier loading into a firearm's internal box magazine. After the bolt is opened and the stripper clip is placed in position (generally in a slot on the receiver or bolt), the cartridges are pressed down, removing or "stripping" them off the clip and into the magazine. The clip is then either removed and tos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magazine (firearms)
A magazine, often simply called a mag, is an ammunition storage and feeding device for a repeating firearm, either integral within the gun (internal/fixed magazine) or externally attached (detachable magazine). The magazine functions by holding several cartridge (firearms), cartridges within itself and sequentially pushing each one into a position where it may be readily loaded into the gun barrel, barrel chamber (firearms), chamber by the firearm's moving action (firearms), action. The detachable magazine is sometimes colloquially referred to as a "clip (ammunition), clip", although this is technically inaccurate since a clip is actually an accessory device used to help load ammunition into a magazine or cylinder. Magazines come in many shapes and sizes, from integral tubular magazines on lever-action and pump-action rifles and shotguns, that may hold more than five rounds, to detachable box magazines and drum magazines for automatic rifles and light machine guns, that may h ...

Primer (firearms)
In firearms and artillery, the primer () is the chemical and/or device responsible for initiating the propellant combustion that will propel the projectiles out of the gun barrel. In early black powder guns such as muzzleloaders, the primer was essentially the same chemical as the main propellant (albeit usually in a finer-powdered form), but poured into an external flash pan, where it could be ignited by an ignition source such as a slow match or a flintlock, though some muzzleloaders have primers like cap gun caps. This external powder was connected through a small opening at the rear of the gun barrel that led to the main charge within the barrel. As gunpowder will not burn when wet, this made it difficult (or even impossible) to fire these types of weapons in rainy or humid conditions. Modern primers, by contrast, are more specialized and distinct from the main propellant they are designed to ignite. They are of two types, those using shock-sensitive chemicals, and those r ...

Propellant
A propellant (or propellent) is a mass that is expelled or expanded in such a way as to create a thrust or another motive force in accordance with Newton's third law of motion, and "propel" a vehicle, projectile, or fluid payload. In vehicles, the engine that expels the propellant is called a reaction engine. Although technically a propellant is the reaction mass used to create thrust, the term "propellant" is often used to describe a substance which contains both the reaction mass and the fuel that holds the energy used to accelerate the reaction mass. For example, the term "propellant" is often used in chemical rocket design to describe a combined fuel/propellant, although the propellants should not be confused with the fuel that is used by an engine to produce the energy that expels the propellant. Even though the byproducts of substances used as fuel are also often used as a reaction mass to create the thrust, such as with a chemical rocket engine, propellant and fuel a ...

Cartridge (firearms)
A cartridge, also known as a round, is a type of pre-assembled firearm ammunition packaging a projectile ( bullet, shot, or slug), a propellant substance ( smokeless powder, black powder substitute, or black powder) and an ignition device ( primer) within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of a breechloading gun, for convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often used to refer to a complete cartridge, the correct usage only refers to the projectile. Military and commercial producers continue to pursue the goal of caseless ammunition. Some artillery ammunition uses the same cartridge concept as found in small arms. In other cases, the artillery shell is separate from the propellant charge. A cartridge without a projectile is called a '' blank''; one that is completely inert (contains no active primer and no propellant) is called a '' dummy''; one that ...

Percussion Cap
The percussion cap, percussion primer, or caplock, introduced in the early 1820s, is a type of single-use percussion ignition device for muzzle loader firearm locks enabling them to fire reliably in any weather condition. Its invention gave rise to the caplock mechanism or percussion lock system which used percussion caps struck by the hammer to set off the gunpowder charge in rifles and cap and ball firearms. Any firearm using a caplock mechanism is a percussion gun. Any long gun with a cap-lock mechanism and rifled barrel is a percussion rifle. Cap and ball describes cap-lock firearms discharging a single bore-diameter spherical bullet with each shot. Description The percussion cap is a small cylinder of copper or brass with one closed end. Inside the closed end is a small amount of a shock-sensitive explosive material such as mercury fulminate (discovered in 1800; it was the only practical detonator used from about the mid-19th century to the early 20th century). ...
