Lawn Mowers
A lawn mower (also known as a grass cutter or simply mower, also often spelled lawnmower) is a device utilizing one or more revolving blades (or a reel) to cut a grass surface to an even height. The height of the cut grass may be fixed by the mower's design but generally is adjustable by the operator, typically by a single master lever or by a mechanism on each of the machine's wheels. The blades may be powered by manual force, with wheels mechanically connected to the cutting blades so that the blades spin when the mower is pushed forward, or the machine may have a battery-powered or plug-in electric motor. The most common self-contained power source for lawn mowers is a small 4-stroke (typically one-cylinder) internal combustion engine. Smaller mowers often lack any form of self-propulsion, requiring human power to move over a surface; "walk-behind" mowers are self-propelled, requiring a human only to walk behind and guide them. Larger lawn mowers are usually either self-p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lawn Mowing DVIDS119604
A lawn () is an area of soil-covered land planted with grasses and other durable plants such as clover which are maintained at a short height with a lawn mower (or sometimes grazing animals) and used for aesthetic and recreational purposes—it is also commonly referred to as part of a garden. Lawns are usually composed only of grass species, subject to weed and pest control, maintained in a green color (e.g., by watering), and are regularly mowed to ensure an acceptable length. Lawns are used around houses, apartments, commercial buildings and offices. Many city parks also have large lawn areas. In recreational contexts, the specialised names turf, parade, pitch, field or green may be used, depending on the sport and the continent. The term "lawn", referring to a managed grass space, dates to at least the 16th century. With suburban expansion, the lawn has become culturally ingrained in some areas of the world as part of the desired household aesthetic.Robbins, PaulLawn ...

Edwin Beard Budding
Edwin Beard Budding (25 August 1796 – 25 September 1846), an engineer born in Eastington, Stroud, Gloucestershire, was the English inventor of the lawnmower (1830) and adjustable spanner (1842). Lawnmower Budding had the idea of the lawnmower after seeing a machine in a local cloth mill that used a cutting cylinder (or bladed reel) mounted on a bench to trim the irregular nap from the surface of woolen cloth and give a smooth finish. Budding's mower was designed primarily to cut the lawn on sports grounds and extensive gardens, as a superior alternative to the scythe A scythe (, rhyming with ''writhe'') is an agriculture, agricultural hand-tool for mowing grass or Harvest, harvesting Crop, crops.

Tennis
Tennis is a List of racket sports, racket sport that is played either individually against a single opponent (singles (tennis), singles) or between two teams of two players each (doubles (tennis), doubles). Each player uses a tennis racket strung with a cord to strike a hollow rubber tennis ball, ball covered with felt over or around a net and into the opponent's tennis court, court. The object is to manoeuvre the ball in such a way that the opponent is not able to play a valid return. If a player is unable to return the ball successfully, the opponent scores a Point (tennis), point. Playable at all levels of society and at all ages, tennis can be played by anyone who can hold a racket, including Wheelchair tennis, wheelchair users. The original forms of tennis developed in France during the late Middle Ages. The modern form of tennis originated in Birmingham, England, in the late 19th century as lawn tennis. It had close connections to various field (lawn) games such as croqu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bowls
Bowls, also known as lawn bowls or lawn bowling, is a sport in which players try to roll their ball (called a bowl) closest to a smaller ball (known as a "jack" or sometimes a "kitty"). The bowls are shaped (biased), so that they follow a curved path when being rolled. The game is played either in teams or one against one. The game was first played in the 13th century. The game is played on grass, although other surfaces are sometimes used. Matches are held either until one player gets to a score, or when a number of ''ends'' are played. The game is mostly played on a bowling green, which can vary by the type of bowls being played. Whilst the game is often played outdoors, there are indoor bowling venues, and can also be played on rollable carpets. For outdoor games, this is usually on grass; however, it can also be played on cotula in New Zealand. History Bowls is a variant of the ''boules'' games (Italian: ''bocce''), which, in their general form, are of ancient or prehistor ...

Football
Football is a family of team sports that involve, to varying degrees, kick (football), kicking a football (ball), ball to score a goal (sports), goal. Unqualified, football (word), the word ''football'' generally means the form of football that is the most popular where the word is used. Sports commonly called ''football'' include association football (known as ''soccer'' in Australia, Canada, South Africa, the United States, and sometimes in Ireland and New Zealand); Australian rules football; Gaelic football; gridiron football (specifically American football, arena football, or Canadian football); International rules football; rugby league, rugby league football; and rugby union, rugby union football. These various forms of football share, to varying degrees, common origins and are known as "football codes". There are a number of references to traditional, ancient, or prehistoric ball games played in many different parts of the world. Contemporary codes of football can be t ...

Grass Court
A grass court is one of the types of tennis court on which the sport of tennis, originally known as "lawn tennis", is played. Grass courts are made of grasses in different compositions depending on the tournament. While grass courts are more traditional than other types of tennis courts, they are far less commonly used today compared to hard courts and clay courts. There are several disadvantages with grass courts: in particular, they are much more expensive to maintain compared to other surfaces. Also, grass courts (in the absence of suitable covers) are usually unplayable for the day if rain appears, as grass becomes very slippery when wet and will not dry for many hours. In contrast, play on a hard court can resume in 30 to 120 minutes after the end of rain, and clay courts can even remain playable in light rain. Furthermore, since most of the foot traffic during a tennis match occurs repetitively over a small surface area of the court, even with the best maintenance a grass ...

Pitch (sports Field)
A pitch or a sports ground is an outdoor playing area for various sports. The term ''pitch'' is most commonly used in British English, while the comparable term in Australian, American and Canadian English is playing field or sports field. For most sports the official term is field of play, although this is not regularly used by those outside refereeing/umpiring circles. The field of play generally includes out-of-bounds areas that a player is likely to enter while playing a match, such as the area beyond the touchlines in association football and rugby or the sidelines in American and Canadian football, or the " foul territory" in baseball. The surface of a pitch is most commonly composed of sod (grass), but may also be artificial turf, sand, clay, gravel, concrete, or other materials. A playing field on ice may be referred to as a ''rink'', for example an ice hockey rink, although ''rink'' may also refer to the entire building or, in the sport of curling, to either th ...

London Zoo
London Zoo, previously known as ZSL London Zoo or London Zoological Gardens and sometimes called Regent's Park Zoo, is the world's oldest scientific zoo. It was opened in London on 27 April 1828 and was originally intended to be used as a collection for scientific study. In 1831 or 1832, the Tower of London menagerie animals were transferred to the zoo's collection. It was opened to the public in 1847. As of December 2022, it houses a collection of 14,926 individuals, making it one of the largest collections in the United Kingdom. It is managed under the aegis of the Zoological Society of London (established in 1826) and is situated at the northern edge of Regent's Park, on the boundary line between the City of Westminster and the borough of Camden (the Regent's Canal runs through it). The Society also has a more spacious site at Whipsnade Zoo in Bedfordshire where larger animals, such as elephants and rhinos, have been moved. As well as being the first scientific zoo, Lond ...

Gear
A gear or gearwheel is a rotating machine part typically used to transmit rotational motion and/or torque by means of a series of teeth that engage with compatible teeth of another gear or other part. The teeth can be integral saliences or cavities machined on the part, or separate pegs inserted into it. In the latter case, the gear is usually called a cogwheel.

Cast Iron
Cast iron is a class of iron–carbon alloys with a carbon content of more than 2% and silicon content around 1–3%. Its usefulness derives from its relatively low melting temperature. The alloying elements determine the form in which its carbon appears: Cast iron#White cast iron, white cast iron has its carbon combined into an iron carbide named cementite, which is very hard, but brittle, as it allows cracks to pass straight through; Grey iron, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and Ductile iron, ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable iron, malleable cast irons. With its relatively low melting point, g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wrought Iron
Wrought iron is an iron alloy with a very low carbon content (less than 0.05%) in contrast to that of cast iron (2.1% to 4.5%), or 0.25 for low carbon "mild" steel. Wrought iron is manufactured by heating and melting high carbon cast iron in an open charcoal or coke hearth or furnace in a process known as puddling. The high temperatures cause the excess carbon to oxidise, the iron being stirred or puddled during the process in order to achieve this. As the carbon content reduces, the melting point of the iron increases, ultimately to a level which is higher than can be achieved by the hearth, hence the wrought iron is never fully molten and many impurities remain. The primary advantage of wrought iron over cast iron is its malleability - where cast iron is too brittle to bend or shape without breaking, wrought iron is highly malleable, and much easier to bend. Wrought iron is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which give it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
