Pickaxe
A pickaxe, pick-axe, or pick is a generally T-shaped hand tool used for 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 "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 mining, and adapted to warfare. Etymology The Oxford Dictionary of English states that both "pick" and "pickaxe" have the same meaning, that being a tool with a long hand ...

Lester Maddox
Lester Garfield Maddox Sr. (September 30, 1915 – June 25, 2003) was an American politician who served as the 75th governor of the U.S. state of Georgia from 1967 to 1971. A populist Democrat, Maddox came to prominence as a staunch segregationist when he refused to serve black customers in his Atlanta restaurant, the Pickrick, in violation of the Civil Rights Act of 1964. He later served as Georgia lieutenant governor under Jimmy Carter. Childhood Maddox was born in Atlanta, Georgia, the second of nine children born to Dean Garfield Maddox, a steelworker, and his wife, the former Flonnie Castleberry. Maddox left school shortly before graduation to help support the family by taking odd jobs, including real estate and grocery. He received his high school diploma through correspondence courses. During World War II, Maddox worked at the Bell Aircraft factory in Marietta, Georgia producing the B-29 Superfortress bomber. Restaurant owner In 1944, Maddox, along with his wife Hat ...

Mattock
A mattock is a hand tool used for digging, prying, and chopping. Similar to the pickaxe, it has a long handle and a stout head which combines either a vertical axe blade with a horizontal adze (cutter mattock), or a pick and an adze (pick mattock). A cutter mattock is similar to a Pulaski used in fighting fires. It is also commonly known in North America as a "grub axe". Description A mattock has a shaft, typically made of wood, which is long. The head consists of two ends, opposite each other and separated by a central eye. A mattock head typically weighs . The form of the head determines the kind and uses of the mattock: * A ''cutter mattock'' combines the functions of an axe and adze, with its axe blade oriented vertically and longer adze horizontally. * A ''pick mattock'' combines the function of a pick and adze, with a pointed end opposite an adze blade. Both are used for grubbing in hard soils and rocky terrain, with the pick mattock having the advantage of a superi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Club (weapon)
A club (also known as a cudgel, baton, bludgeon, truncheon, cosh, nightstick, or impact weapon) is a short staff or stick, usually made of wood, wielded as a weapon since prehistoric times. There are several examples of blunt-force trauma caused by clubs in the past, including at the site of Nataruk in Turkana, Kenya, described as the scene of a prehistoric conflict between bands of hunter-gatherers 10,000 years ago. Most clubs are small enough to be swung with one hand, although larger clubs may require the use of two to be effective. Various specialized clubs are used in martial arts and other fields, including the law-enforcement baton. The military mace is a more sophisticated descendant of the club, typically made of metal and featuring a spiked, knobbed, or flanged head attached to a shaft. Examples of cultural depictions of clubs may be found in mythology, where they are associated with strong figures such as Hercules or the Japanese oni, or in popular culture, wh ...

Traditional Mining
Traditional mining, also known as old-school mining, is a mining method involving the use of simple manual tools, such as shovels, pickaxes, hammers, chisels and pans. It is done in both surface and underground environments. Until the early 1900s, traditional mining was widely used throughout the world. It is still a used mining method in some countries, including Colombia and Peru in South America and Niger in Africa. In traditional surface and underground mining, hammers and chisels with pickaxes and shovels are used. Minecarts are used to move ore and other materials in the process of mining. Pans are used for placer mining operations, such as gold panning. The traditional method of cracking rock was fire-setting, which involved heating the rock with fire to expand it. Once the rock was heated by fire it was quenched with water to break it. Fire-setting was one of the most effective rock breaking methods until 1867 when Alfred Nobel invented dynamite.

Ice Axe
An ice axe is a multi-purpose hiking and climbing tool used by mountaineers in both the ascent and descent of routes that involve snow, ice, or frozen conditions. Its use depends on the terrain: in its simplest role it is used like a walking stick, with the mountaineer holding the head in the center of their uphill hand. On steep terrain it is swung by its handle and embedded in snow or ice for security and an aid to traction. It can also be buried pick down, the rope tied around the shaft to form a secure anchor on which to bring up a second climber, or buried vertically to form a stomp belay. The adze is used to cut footholds, as well as scoop out compacted snow to bury the axe as a belay anchor. History The ice axe of today has its roots in the long-handled alpenstock that came before it. Not only is an ice axe used as a climbing aid, but also as a means of self-arrest in the event of a slip downhill. Most ice axes meet design and manufacturing standards of organi ...

Hickory
Hickory is a common name for trees composing the genus ''Carya'', which includes around 18 species. Five or six species are native to China, Indochina, and India (Assam), as many as twelve are native to the United States, four are found in Mexico, and two to four are native to Canada. A number of hickory species are used for products like edible nuts or wood. Hickories are temperate forest trees with pinnately compound leaves and large nuts. Hickory flowers are small, yellow-green catkins produced in spring. They are wind-pollinated and self-incompatible. The fruit is a globose or oval nut, long and diameter, enclosed in a four- valved husk, which splits open at maturity. The nut shell is thick and bony in most species, and thin in a few, notably the pecan (''C. illinoinensis''); it is divided into two halves, which split apart when the seed germinates. Etymology The name "hickory" derives from a Native American word in an Algonquian language (perhaps Powhatan). I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Grapes Of Wrath
''The Grapes of Wrath'' is an American realist novel written by John Steinbeck and published in 1939. The book won the National Book Award and Pulitzer Prize for fiction, and it was cited prominently when Steinbeck was awarded the Nobel Prize in 1962. Set during the Great Depression, the novel focuses on the Joads, a poor family of tenant farmers driven from their Oklahoma home by drought, economic hardship, agricultural industry changes, and bank foreclosures forcing tenant farmers out of work. Due to their nearly hopeless situation, and in part because they are trapped in the Dust Bowl, the Joads set out for California along with thousands of other " Okies" seeking jobs, land, dignity, and a future. ''The Grapes of Wrath'' is frequently read in American high school and college literature classes due to its historical context and enduring legacy. A celebrated Hollywood film version, starring Henry Fonda and directed by John Ford, was released in 1940. Plot The narrative ...

CFRPs can be expensive to produce, but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, superstructures of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications. The binding polymer is often a thermosetting polymer, thermoset resin such as epoxy, but oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pound (mass)
The pound or pound-mass is a unit of mass used in British imperial and United States customary systems of measurement. Various definitions have been used; the most common today is the international avoirdupois pound, which is legally defined as exactly , and which is divided into 16 avoirdupois ounces. The international standard symbol for the avoirdupois pound is lb; an alternative symbol is lbm (for most pound definitions), # ( chiefly in the U.S.), and or ″̶ (specifically for the apothecaries' pound). The unit is descended from the Roman (hence the abbreviation "lb"). The English word ''pound'' is cognate with, among others, German , Dutch , and Swedish . These units are historic and are no longer used (replaced by the metric system). Usage of the unqualified term ''pound'' reflects the historical conflation of mass and weight. This accounts for the modern distinguishing terms ''pound-mass'' and ''pound-force''. Etymology The word 'pound' and its cognate ...

Ash Tree
''Fraxinus'' (), commonly called ash, is a genus of flowering plants in the olive and lilac family, Oleaceae. It contains 45–65 species of usually medium to large trees, mostly deciduous, though a number of subtropical species are evergreen. The genus is widespread across much of Europe, Asia, and North America. The leaves are opposite (rarely in whorls of three), and mostly pinnately compound, though simple in a few species. The seeds, popularly known as "keys" or "helicopter seeds", are a type of fruit known as a samara. Some ''Fraxinus'' species are dioecious, having male and female flowers on separate plants but sex in ash is expressed as a continuum between male and female individuals, dominated by unisexual trees. With age, ash may change their sexual function from predominantly male and hermaphrodite towards femaleness ; if grown as an ornamental and both sexes are present, ashes can cause a considerable litter problem with their seeds. Rowans or mountain ashes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Army
The British Army is the principal land warfare force of the United Kingdom, a part of the British Armed Forces along with the Royal Navy and the Royal Air Force. , the British Army comprises 79,380 regular full-time personnel, 4,090 Gurkhas, and 28,330 volunteer reserve personnel. The modern British Army traces back to 1707, with antecedents in the English Army and Scots Army that were created during the Restoration in 1660. The term ''British Army'' was adopted in 1707 after the Acts of Union between England and Scotland. Members of the British Army swear allegiance to the monarch as their commander-in-chief, but the Bill of Rights of 1689 and Claim of Right Act 1689 require parliamentary consent for the Crown to maintain a peacetime standing army. Therefore, Parliament approves the army by passing an Armed Forces Act at least once every five years. The army is administered by the Ministry of Defence and commanded by the Chief of the General Staff. The British ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
