Crowbar (American Band) Albums
A crowbar, also called a wrecking bar, pry bar or prybar, pinch-bar, or occasionally a prise bar or prisebar, colloquially gooseneck, or pig foot, or in Britain and Australia a jemmy or jimmy (also called jemmy bar), is a lever consisting of a metal bar with a single curved end and flattened points, used to force two objects apart or gain mechanical advantage in lifting; often the curved end has a notch for removing nails. The design can be used as any of the three lever classes. The curved end is usually used as a first-class lever, and the flat end as a second-class lever. Designs made from thick flat steel bar are often referred to as utility bars. Materials and construction A common hand tool, the crow bar is typically made of medium-carbon steel, possibly hardened on its ends. Commonly crowbars are forged from long steel stock, either hexagonal or sometimes cylindrical. Alternative designs may be forged with a rounded I-shaped cross-section shaft. Versions using rel ...

Daniel Defoe
Daniel Defoe (; born Daniel Foe; – 24 April 1731) was an English writer, trader, journalist, pamphleteer and spy. He is most famous for his novel ''Robinson Crusoe'', published in 1719, which is claimed to be second only to the Bible in its number of translations. He has been seen as one of the earliest proponents of the English novel, and helped to popularise the form in Britain with others such as Aphra Behn and Samuel Richardson. Defoe wrote many political tracts, was often in trouble with the authorities, and spent a period in prison. Intellectuals and political leaders paid attention to his fresh ideas and sometimes consulted him. Defoe was a prolific and versatile writer, producing more than three hundred works—books, pamphlets, and journals — on diverse topics, including politics, crime, religion, marriage, psychology, and the supernatural. He was also a pioneer of business journalism and economic journalism. Early life Daniel Foe (his original name) was probabl ...

Hand Tools
A hand tool is any tool that is powered by hand rather than a motor. Categories of hand tools include wrenches, pliers, cutters, files, striking tools, struck or hammered tools, screwdrivers, vises, clamps, snips, hacksaws, drills, and knives. Outdoor tools such as garden forks, pruning shears, and rakes are additional forms of hand tools. Portable power tools are not hand tools. History Hand tools have been used by humans since the Stone Age when stones were used for hammering and cutting. During the Bronze Age tools were made by casting the copper and tin alloys. Bronze tools were sharper and harder than those made of stone. During the Iron Age iron replaced bronze, and tools became even stronger and more durable. The Romans developed tools during this period which are similar to those being produced today. In the period since the industrial revolution, the manufacture of tools has transitioned from being craftsman made to being factory produced. A large collection of ...

Tire Iron
A tire iron (also tire lever or tire spoon) is a specialized metal tool used in working with tires. Tire irons have not been in common use for automobile tires since the shift to the use of tubeless tires in the late 1950s. Bicycle tire irons are still in use for those tires which have a separate inner tube, and can have a hooked C-shape cut into one end of the iron so that it may be hooked on a bicycle spoke to hold it in place. Description and use Tire irons, which usually come in pairs or threes, are used to pry the edge of a tire away from the rim of the wheel it has been mounted on. After one iron has pried a portion of the tire from its wheel, it is held in position while a second iron is applied further along the tire to pry more of the tire away from the wheel. This allows enough of the tire to be separated so that the first iron can be removed, and used again on the far side of the other iron. Alternating in this way, a person can work all the way around the tire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kinetic Energy Penetrator
A kinetic energy penetrator (KEP), also known as long-rod penetrator (LRP), is a type of ammunition designed to penetrate vehicle armour using a flechette-like, high-sectional density projectile. Like a bullet or kinetic energy weapon, this type of ammunition does not contain explosive payloads and uses purely kinetic energy to penetrate the target. Modern KEP munitions are typically of the armour-piercing fin-stabilized discarding sabot (APFSDS) type. History Early cannons fired kinetic energy ammunition, initially consisting of heavy balls of worked stone and later of dense metals. From the beginning, combining high muzzle energy with projectile weight and hardness have been the foremost factors in the design of such weapons. Similarly, the foremost purpose of such weapons has generally been to defeat protective shells of armored vehicles or other defensive structures, whether it is stone walls, sailship timbers, or modern tank armour. Kinetic energy ammunition, in its vari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Halligan Bar
A Halligan bar (also known as a Halligan tool or Hooligan tool) is a forcible entry tool used by firefighters. History The Halligan bar was designed by New York City Fire Department (FDNY) First Deputy Chief Hugh Halligan in 1948 and was named after him. That same year, blacksmith Peter Clarke made the first prototype of the tool. Despite its popularity among FDNY ladder companies, the department initially refrained from purchasing the tool to avoid the appearance of a conflict of interest.''Fire Department City of New York: The Bravest; An Illustrated History 1865-2002'', page 72. However, the Boston Fire Department was the first major customer of the Halligan bar, purchasing one for every fire company in the city. This led to widespread adoption of the tool, first in North America and eventually worldwide. The Halligan bar has become the most versatile hand tool for fireground tasks over the past seven decades. Design Based on the earlier Kelly tool, the Halligan is a multipur ...

Digging Bar
A digging bar is a long, straight metal bar used for various purposes, including as a post hole digger, to break up or loosen hard or compacted materials such as soil, rock, concrete and ice or as a lever to move objects. Known by other names depending on locale, structural features and intended purpose such as a hop bar or crowbar in Britain, Australia and New Zealand, and slate bar, shale bar, spud bar, pinch point bar or San Angelo bar in North America, or just a bar. In Hawaii, a similar, traditional wooden device known as an ''‘o‘o stick'' is used as a digging bar in groundbreaking ceremonies. Not to be confused with a curved crowbar, which is designed to provide leverage rather than to dig. Uses Common uses of digging bars include breaking up clay, concrete, frozen ground, and other hard materials, moving or breaking up tree roots and obstacles, and making holes in the ground for fence posts. They are often used where space would not allow the use of a pickaxe. Mat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cat's Paw (tool)
A cat's paw with extracting notches on each end. Typical lengths vary between long A cat's paw or cat's claw is a metal hand tool used for extracting nails, typically from wood, using lever A lever is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or '' fulcrum''. A lever is a rigid body capable of rotating on a point on itself. On the basis of the locations of fulcrum, load and effort, the lever is d ...age. A standard tool in carpentry, it has a sharp V-shaped tip on one or both ends, which is driven into the wood by a hammer to capture the nailhead. Essentially, it is a smaller, more ergonomic, purpose-designed crowbar. Historically, the cat's paw had a single significantly rounder, more cup-shaped extracting head, giving it its name. Today, the norm is to have the two much narrower and more pointed heads offset 90-degrees (in plane) from one-another (allowing the bar to be pressed fully down when using the tip on the long end witho ...

Pickaxe
A pickaxe, pick-axe, or pick is a generally T-shaped hand tool used for Leverage (mechanics), prying. Its head is typically metal, attached perpendicularly to a longer handle, traditionally made of wood, occasionally metal, and increasingly fiberglass. A standard pickaxe, similar to a "mattock, pick mattock", has a pointed end on one side of its head and a broad flat "axe" blade opposite. A gradual curve characteristically spans the length of the head. The next most common configuration features two spikes, one slightly longer than the other. The pointed end is used both for breaking and prying, the axe for hoeing, skimming, and chopping through roots. Developed as agricultural tools in prehistoric times, picks have evolved into other tools such as the plough and the mattock. They also have been used in general construction and traditional mining, mining, and adapted to warfare. Etymology The Oxford Dictionary of English states that both "pick" and "pickaxe" have the ...

Robinson Crusoe
''Robinson Crusoe'' () is a novel by Daniel Defoe, first published on 25 April 1719. The first edition credited the work's protagonist Robinson Crusoe as its author, leading many readers to believe he was a real person and the book a travelogue of true incidents. Epistolary, confessional, and didactic in form, the book is presented as an autobiography of the title character (whose birth name is Robinson Kreutznaer) – a castaway who spends 28 years on a remote tropical desert island near the coasts of Venezuela and Trinidad, roughly resembling Tobago, encountering cannibals, captives, and mutineers before being rescued. The story has been thought to be based on the life of Alexander Selkirk, a Scottish castaway who lived for four years on a Pacific island called "Más a Tierra" (now part of Chile) which was renamed Robinson Crusoe Island in 1966. Despite its simple narrative style, ''Robinson Crusoe'' was well received in the literary world and is often credited as ma ...

Romeo And Juliet
''Romeo and Juliet'' is a Shakespearean tragedy, tragedy written by William Shakespeare early in his career about the romance between two Italian youths from feuding families. It was among Shakespeare's most popular plays during his lifetime and, along with ''Hamlet'', is one of his most frequently performed plays. Today, the Title character, title characters are regarded as archetype, archetypal young lovers. ''Romeo and Juliet'' belongs to a tradition of tragic Romance (love), romances stretching back to Ancient history, antiquity. The plot is based on an Italian tale translated into verse as ''The Tragical History of Romeus and Juliet'' by Arthur Brooke (poet), Arthur Brooke in 1562 and retold in prose in ''Palace of Pleasure'' by William Painter (author), William Painter in 1567. Shakespeare borrowed heavily from both but expanded the plot by developing a number of supporting characters, particularly Mercutio and Count Paris, Paris. Believed to have been written between ...

Lever
A lever is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or ''fulcrum''. A lever is a rigid body capable of rotating on a point on itself. On the basis of the locations of fulcrum, load and effort, the lever is divided into three types. Also, leverage is mechanical advantage gained in a system. It is one of the six simple machines identified by Renaissance scientists. A lever amplifies an input force to provide a greater output force, which is said to provide leverage. The ratio of the output force to the input force is the mechanical advantage of the lever. As such, the lever is a mechanical advantage device, trading off force against movement. Etymology The word "lever" entered English around 1300 from Old French, in which the word was ''levier''. This sprang from the stem of the verb ''lever'', meaning "to raise". The verb, in turn, goes back to the Latin ''levare'', itself from the adjective ''levis'', meaning "light" (as in "not heavy"). The ...
