Steelyard Balance
A steelyard balance, steelyard, or stilyard is a straight-beam balance with arms of unequal length. It incorporates a counterweight which slides along the longer arm to counterbalance the load and indicate its weight. A steelyard is also known as a Roman steelyard or Roman balance. Structure The steelyard comprises a balance beam which is suspended from a lever/pivot or fulcrum which is very close to one end of the beam. The two parts of the beam which flank the pivot are the arms. The arm from which the object to be weighed (the load) is hung is short and is located close to the pivot point. The other arm is longer, is graduated and incorporates a counterweight which can be moved along the arm until the two arms are balanced about the pivot, at which time the weight of the load is indicated by the position of the counterweight. Mechanism The steelyard exemplifies the law of the lever, wherein, when balanced, the weight of the object being weighed, multiplied by the length of ...

Weighing Scale
A scale or balance is a device used to measure weight or mass. These are also known as mass scales, weight scales, mass balances, and weight balances. The traditional scale consists of two plates or bowls suspended at equal distances from a fulcrum. One plate holds an object of unknown mass (or weight), while known masses are added to the other plate until static equilibrium is achieved and the plates level off, which happens when the masses on the two plates are equal. The perfect scale rests at neutral. A spring scale will make use of a spring of known stiffness to determine mass (or weight). Suspending a certain mass will extend the spring by a certain amount depending on the spring's stiffness (or spring constant). The heavier the object, the more the spring stretches, as described in Hooke's law. Other types of scales making use of different physical principles also exist. Some scales can be calibrated to read in units of force (weight) such as newtons instead of unit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Shipwreck At Black Assarca Island, Eritrea
The Black Assarca shipwreck was first discovered by tourists in 1995, at Black Assarca Island, Eritrea. The wreck was surveyed in 1995 and partially excavated in 1997 by the Institute of Nautical Archaeology, under the auspices of the Ministry of Marine Resources of Eritrea. The 1997 excavation team, headed by Ralph K. Pedersen, discovered various artifacts of Near Eastern/Mediterranean origin, including amphoras of a type known as "Ayla-Axum Amphoras", or more accurately "Aqaba Amphoras" after their point of manufacture. These long and conical "carrot shaped" amphoras, decorated with corrugations, or rilling, have been found previously at such sites as: Aksum, the capital of the Aksumite Kingdom; Metara; Adulis, the Aksumite port city located on the west side of Zula Bay; Berenike, the Ptolemaic harbor in Egypt; and Aqaba, Jordan. Based on the finds at these sites, the Black Assarca ceramics are thought to date from around the 5th or 6th century, with the wreck possibly dating fro ...

Scandinavia
Scandinavia; Sámi languages: /. ( ) is a subregion#Europe, subregion in Northern Europe, with strong historical, cultural, and linguistic ties between its constituent peoples. In English usage, ''Scandinavia'' most commonly refers to Denmark, Norway, and Sweden. It can sometimes also refer more narrowly to the Scandinavian Peninsula (which excludes Denmark but includes part of Finland), or more broadly to include all of Finland, Iceland, and the Faroe Islands. The geography of the region is varied, from the Norwegian fjords in the west and Scandinavian mountains covering parts of Norway and Sweden, to the low and flat areas of Denmark in the south, as well as archipelagos and lakes in the east. Most of the population in the region live in the more temperate southern regions, with the northern parts having long, cold, winters. The region became notable during the Viking Age, when Scandinavian peoples participated in large scale raiding, conquest, colonization and trading mostl ...

Horse Drawn Cart
A cart or dray (Australia and New Zealand) is a vehicle designed for transport, using two wheels and normally pulled by one or a pair of draught animals. A handcart is pulled or pushed by one or more people. It is different from the flatbed trolley also known as a dray, (for freight) or wagon, which is a heavy transport vehicle with four wheels and typically two or more humans. Over time, the term "cart" has come to mean nearly any small conveyance, including shopping carts, golf carts, gokarts, and UTVs, without regard to number of wheels, load carried, or means of propulsion. The draught animals used for carts may be horses, donkeys or mules, oxen, and even smaller animals such as goats or large dogs. History Carts have been mentioned in literature as far back as the second millennium B.C. Handcarts pushed by humans have been used around the world. In the 19th century, for instance, some Mormons traveling across the plains of the United States between 1856 and 1860 used ...

Historic England
Historic England (officially the Historic Buildings and Monuments Commission for England) is an executive non-departmental public body of the British Government sponsored by the Department for Digital, Culture, Media and Sport. It is tasked with protecting the historic environment of England by preserving and listing historic buildings, scheduling ancient monuments, registering historic Parks and Gardens and by advising central and local government. The body was officially created by the National Heritage Act 1983, and operated from April 1984 to April 2015 under the name of English Heritage. In 2015, following the changes to English Heritage's structure that moved the protection of the National Heritage Collection into the voluntary sector in the English Heritage Trust, the body that remained was rebranded as Historic England. The body also inherited the Historic England Archive from the old English Heritage, and projects linked to the archive such as Britain from Above, w ...

Hanseatic League
The Hanseatic League (; gml, Hanse, , ; german: label=Modern German, Deutsche Hanse) was a medieval commercial and defensive confederation of merchant guilds and market towns in Central and Northern Europe. Growing from a few North German towns in the late 12th century, the League ultimately encompassed nearly 200 settlements across seven modern-day countries; at its height between the 13th and 15th centuries, it stretched from the Netherlands in the west to Russia in the east, and from Estonia in the north to Kraków, Poland in the south. The League originated from various loose associations of German traders and towns formed to advance mutual commercial interests, such as protection against piracy and banditry. These arrangements gradually coalesced into the Hanseatic League, whose traders enjoyed duty-free treatment, protection, and diplomatic privileges in affiliated communities and their trade routes. Hanseatic Cities gradually developed a common legal system governing t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
