Lever
A lever is a simple machine consisting of a beam (structure), beam or rigid rod pivoted at a fixed hinge, or '':wikt:fulcrum, 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 Lever#Types of levers, three types. 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, which is mechanical advantage gained in the system, equal to the ratio of the output force to the input force. As such, the lever is a mechanical advantage device, trading off force against movement. Etymology The word "lever" entered English language, English around 1300 from . This sprang from the stem of the verb ''lever'', meaning "to raise". The verb, in turn, goes back to , itself from the adjective ''levis'', meaning "light" (as in "not heavy"). The word's primary origin is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pivot Language
A pivot language, sometimes also called a bridge language, is an artificial or natural language used as an intermediary language for translation between many different languages – to translate between any pair of languages A and B, one translates A to the pivot language P, then from P to B. Using a pivot language avoids the combinatorial explosion of having translators across every combination of the supported languages, as the number of combinations of language is linear (n-1), rather than quadratic \left(\textstyle=\frac\right) – one need only know the language A and the pivot language P (and someone else the language B and the pivot P), rather than needing a different translator for every possible combination of A and B. The disadvantage of a pivot language is that each step of retranslation introduces possible mistakes and ambiguities – using a pivot language involves two steps, rather than one. For example, when Hernán Cortés communicated with Mesoamerican Indians, he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rugby League Positions
A rugby league team consists of 13 players on the field, with 4 interchange players on the bench. Each of the 13 players is assigned a position, normally with a standardised number, which reflects their role in attack and defence, although players can take up any position at any time. Players are divided into two general types, forwards and backs. Forwards are generally chosen for their size and strength. They are expected to run with the ball, to attack, and to make tackles. Forwards are required to improve the team's field position thus creating space and time for the backs. Backs are usually smaller and faster, though a big, fast player can be of advantage in the backs. Their roles require speed and ball-playing skills, rather than just strength, to take advantage of the field position gained by the forwards. Typically forwards tend to operate in the centre of the field, while backs operate nearer to the touch-lines, where more space can usually be found. Names and numbering ...

Five-eighth
Five-eighth or stand-off is one of the positions in a rugby league football team. Wearing jersey number 6, this player is one of the two half backs in a team, partnering the . Sometimes known as the pivot or second receiver, in a traditional attacking 'back-line' (No. 1-7) play, the five-eighth would receive the ball from the halfback, who is the first receiver of the ball from the dummy-half or following a tackle. The role of the five-eighth is often to pass the ball away from the congested area around the tackle, further out along the 'back-line' to the outside backs, the centres and wingers, who have more space to run with it. Furthermore, players in this position typically assume responsibility for kicking the ball for field position in general play. The five-eighth is therefore considered one of the most important positions, often referred to as a 'play maker', assuming a decision-making role on the field. Over time, however, as the game has evolved, the roles of the tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Handball (also known as team handball, European handball, Olympic handball or indoor handball) is a team sport in which two teams of seven players each (six outcourt players and a Handball goalkeeper, goalkeeper) pass a ball using their hands with the aim of throwing it into the goal of the opposing team.

The goals are surrounded by a zone where only the defending goalkeeper is allowed; goals must be scored by throwing the ball from outside the zone or while "diving" into it. The sport is usually played indoors, but outdoor variants exist in the forms of field handball, Czech handball (which were more common in the past) and beach handball.

Pivot Peak
The Wilkniss Mountains () form a prominent group of conical peaks and mountains, long running north–south, located east-southeast of Mount Feather in the Quartermain Mountains, Victoria Land, Antarctica. The mountains are wide in the north portion where Mount Blackwelder, high, and Pivot Peak high, rise above ice-free valleys. Except for an outlying southwest peak, the south portion narrows to a series of mainly ice-covered smaller peaks. Name The Wilkniss Mountains were named by United States Advisory Committee on Antarctic Names (US-ACAN) in 1992 after Peter E. Wilkniss, a chemist who from 1975 has served in various positions at the National Science Foundation, including Deputy Assistant Director of the Directorate for Scientific, Technological, and International Affairs; Director, Division of Polar Programs, 1984–93; senior science associate to the assistant director for Geosciences, from 1993.

He defined Afro-Eurasia as the "world island" and its "heartland" as the area east of the Volga, south of the Arctic, west of the Yangtze, and north of the Himalayas. Due to its strategic location and natural resources, Mackinder argued that whoever controlled the "heartland" could control the world.
