Sack (unit)
The sack (abbreviation: sck.) was an English unit of weight or mass used for coal and wool. It has also been used for other commodities by weight, commodities by volume, and for both weight and volume in the United States. Wool The wool sack or woolsack ( la, saccus lanae or ') was standardized as 2 wey of 14 stone each, with each stone merchants' pounds each (''i.e.'' 350 merchants' pounds or about 153 kilograms), by the time of the Assize of Weights and Measures . 12 such sacks formed the wool last.. & & Coal The coal sack was standardized as an imperial hundredweight of 112 avoirdupois pounds, approximately 51 kilograms. Large sack The large sack was a UK unit of weight for coal. It was introduced by the London, Westminster and Home Counties Coal Trade Act of 1831 (2 Will 4 c lxxvi), which required coal to be sold by weight rather than volume. The Royal Navy used large sacks holding two hundredweight for coaling its ships. These sacks were made of jute bou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
English Units
English units are the units of measurement used in England up to 1826 (when they were replaced by Imperial units), which evolved as a combination of the Anglo-Saxon and Roman systems of units. Various standards have applied to English units at different times, in different places, and for different applications. Use of the term "English units" can be ambiguous, as, in addition to the meaning used in this article, it is sometimes used to refer to the units of the descendent Imperial system as well to those of the descendant system of United States customary units. The two main sets of English units were the Winchester Units, used from 1495 to 1587, as affirmed by King Henry VII, and the Exchequer Standards, in use from 1588 to 1825, as defined by Queen Elizabeth I. In England (and the British Empire), English units were replaced by Imperial units in 1824 (effective 1 January 1826) by a Weights and Measures Act, which retained many though not all of the unit names and redefin ...

Avoirdupois Pounds
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 cognates ultimat ...

American Oil Industry
Petroleum has been a major industry in the United States since shortly after the oil discovery in the Oil Creek area of Titusville, Pennsylvania in 1859. The industry includes exploration, production, processing (refining), transportation, and marketing of natural gas and petroleum products.American Petroleum Institute accessed 20 February 2010. In 2018, the U.S. became the worlds largest crude oil producer, producing 15% of global crude oil, surpassing Russia and Saudi Arabia. The leading oil-producing area in the United States in 2019 was Texas ( per day), followed by the offshore federal zone of the Gulf of Mexico ( per day), North Dakota ( per day) and New Mexico ( per day). In 2020, the top five U.S. oil producing states were Texas (43%), North Dakota (10.4%), New Mexico (9.2%), Oklahoma (4.1%), and Colorado (4.0%)''.'' The oil industry extracted a record high 4.47 billion barrels of crude oil in the United States in 2019 (around 12.25 million barrels per day), wor ...

Sack Truck
:''"Hand truck" may also refer to Pallet jack.'' A hand truck, also known as a hand trolley, dolly, stack truck, trundler, box cart, sack barrow, cart, sack truck, two wheeler, or bag barrow, is an L-shaped box-moving handcart with handles at one end, wheels at the base, with a small ledge to set objects on, flat against the floor when the hand-truck is upright. The objects to be moved are tilted forward, the ledge is inserted underneath them, and the objects allowed to tilt back and rest on the ledge. The truck and objects are then tilted backward until the weight is balanced over the wheels, making otherwise bulky and heavy objects easier to move. It is a first-class lever. Overview Sack trucks were originally used in the 18th century to move large sacks of spices on docks by young boys, from the age of 11, who were unable to lift the large sacks by hand. By using this method they were able to work as well as grown men in moving items around. Later, such trucks were amended fo ...

Collier (ship)
A collier is a bulk cargo ship designed or used to carry coal. Early evidence of coal being transported by sea includes use of coal in London in 1306. In the fourteenth and fifteenth centuries, coal was shipped from the River Tyne to London and other destinations. Other ports also exported coal for instance the Old Quay in Whitehaven harbour was built in 1634 for the loading of coal. London became highly reliant on the delivery of coal by sea Samuel Pepys expressed concern in the winter of 166667 that war with the Dutch would prevent a fleet of 200 colliers getting through. In 1795, 4,395 cargoes of coal were delivered to London. By 1824, this number had risen to about 7,000; by 1839, it was over 9,000. The trade continued to the end of the twentieth century, with the last cargo of coal leaving the Port of Tyne in February, 2021. The earliest type of collier on which there is detailed information is the Whitby-built ''cat''. These were bluff-bowed, round-sterned, strongly-buil ...

Manila Rope
Manila rope is a type of rope made from manila hemp. Manila hemp is a type of fiber obtained from the leaves of the abacá Abacá ( ; fil, Abaka ), binomial name ''Musa textilis'', is a species of banana native to the Philippines, grown as a commercial crop in the Philippines, Ecuador, and Costa Rica. The plant, also known as Manila hemp, has great economic impo .... It is not actually hemp, but named so because hemp was long a major source of fiber, and other fibers were sometimes named after it. The name refers to the Manila, capital of the Philippines, one of the main producers of abacá. Applications and properties Manila rope is very durable, flexible, and resistant to Seawater, salt water damage, allowing its use in rope, hawsers, ships' lines, and fishing nets."abaca" ''Encyclopædia Britannica''. 22 January 2007.

Jute
Jute is a long, soft, shiny bast fiber that can be spun into coarse, strong threads. It is produced from flowering plants in the genus ''Corchorus'', which is in the mallow family Malvaceae. The primary source of the fiber is ''Corchorus olitorius'', but such fiber is considered inferior to that derived from ''Corchorus capsularis''. "Jute" is the name of the plant or fiber used to make burlap, hessian, or gunny cloth. Jute is one of the most affordable natural fibers and second only to cotton in the amount produced and variety of uses. Jute fibers are composed primarily of plant materials cellulose and lignin. Jute fiber falls into the bast fiber category (fiber collected from bast, the phloem of the plant, sometimes called the "skin") along with kenaf, industrial hemp, flax ( linen), ramie, etc. The industrial term for jute fiber is ''raw jute''. The fibers are off-white to brown and 1–4 meters (3–13 feet) long. Jute is also called the "golden fiber" for its color an ...

Coaling (ships)
The era of the steam warship powered exclusively by coal was relatively brief, lasting from 1871 until 1914. Although the French ironclad ''Gloire'' and the iron hulled in 1860 both had coal-fired boilers and funnels, their purpose was to provide additional speed in battle. Sails provided their main propulsion most of the time so, unlike , the first ship built without sails, these were not true steamships. Although much faster than sail, the lengthy refueling or coaling required by steam ships brought considerable additional risk to the ship and hardship to the crew. These drawbacks led to the replacement of coal by oil. Coal itself also required maintenance. Coal cannot be pumped and, once loaded, it had to be continuously moved to ensure bunkers nearest the boilers were always full should full power be suddenly needed. These problems were sufficiently serious for the Royal Navy to build as an oil-fired ship despite an abundance of coal and a shortage of oil in the United Kingd ...

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Imperial Hundredweight
The hundredweight (abbreviation: cwt), formerly also known as the centum weight or quintal, is a British imperial and US customary unit of weight or mass. Its value differs between the US and British imperial systems. The two values are distinguished in American English as the "short" and "long" hundredweight and in British English as the "cental" and the "imperial hundredweight". * The short hundredweight or cental of is used in the United States. * The long or imperial hundredweight of 8 stone or is defined in the imperial system. Under both conventions, there are 20 hundredweight in a ton, producing a "short ton" of 2,000 pounds and a " long ton" of 2,240 pounds. History The hundredweight has had many values. In England in around 1300, different "hundreds" (''centum'' in Medieval Latin) were defined. The Weights and Measures Act 1835 formally established the present imperial hundredweight of 112 lb. The United States and Canada came to use the term ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weight
In science and engineering, the weight of an object is the force acting on the object due to gravity. Some standard textbooks define weight as a Euclidean vector, vector quantity, the gravitational force acting on the object. Others define weight as a scalar quantity, the magnitude of the gravitational force. Yet others define it as the magnitude of the reaction (physics), reaction force exerted on a body by mechanisms that counteract the effects of gravity: the weight is the quantity that is measured by, for example, a spring scale. Thus, in a state of free fall, the weight would be zero. In this sense of weight, terrestrial objects can be weightless: ignoring Drag (physics), air resistance, the famous apple falling from the tree, on its way to meet the ground near Isaac Newton, would be weightless. The unit of measurement for weight is that of force, which in the International System of Units (SI) is the newton (unit), newton. For example, an object with a mass of one kilogram ...
