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] |
Player Piano
A player piano is a self-playing piano with a pneumatic or electromechanical mechanism that operates the piano action using perforated paper or metallic rolls. Modern versions use MIDI. The player piano gained popularity as mass-produced home pianos increased in the late 19th and early 20th centuries. Sales peaked in 1924 and subsequently declined with improvements in electrical phonograph recordings in the mid-1920s. The advent of electrical amplification in home music reproduction, brought by radios, contributed to a decline in popularity, and the stock market crash of 1929 virtually wiped out production. History The first practical pneumatic piano player, manufactured by the Aeolian Company and called the "Pianola", was invented in 1896 by Edwin S. Votey, and came into widespread use in the 20th century. The name "pianola", sometimes used as a generic name for any player piano, came from this invention. The mechanism of this player piano was all-pneumatic: foot-operated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peddle
A peddler (American English) or pedlar (British English) is a door-to-door and/or travelling vendor of goods. In 19th-century United States the word "drummer" was often used to refer to a peddler or traveling salesman; as exemplified in the popular play '' Sam'l of Posen; or, The Commercial Drummer'' by George H. Jessop. In England, the term was mostly used for travellers hawking goods in the countryside to small towns and villages. In London, more specific terms were used, such as costermonger. From antiquity, peddlers filled the gaps in the formal market economy by providing consumers with the convenience of door-to-door service. They operated alongside town markets and fairs where they often purchased surplus stocks which were subsequently resold to consumers. Peddlers were able to distribute goods to the more geographically-isolated communities such as those who lived in mountainous regions of Europe. They also called on consumers who, for whatever reason, found it diffic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pedals (bear)
Pedals (died October 2016, New Jersey, United States) was an American black bear (''Ursus americanus'') that Animal locomotion, walked upright on its Hindlimb, hind legs because of injuries on its front paws. After videos of the bear were posted on the internet, more than 300,000 people signed a petition to move the bear to a wildlife sanctuary. However, Pedals appears to have been one of hundreds of bears killed by bullets or arrows in October 2016 in New Jersey's first sanctioned bow and arrow, bow-and-arrow hunt in four decades. Fame Pedals was first spotted walking upright in 2014 in Oak Ridge, New Jersey, spurring debate and discussions. Videos of Pedals' bipedal walking were posted to the internet and he was described as an "internet sensation". Officials initially warned that the videos might be a hoax. Over 300,000 people concerned with Pedals' welfare signed a petition written by Lisa Rose Rublack to relocate the bear to the Orphaned Wildlife Center in Otisville, New Yo ...

Rudder Pedal
A rudder pedal is a foot-operated aircraft flight control interface for controlling the rudder of an aircraft. The usual set-up in modern aircraft is that each pilot has a pedal set consisting of a pair of pedals, with one pedal for each foot. Each right and left pedal works together so that one pedal pops out when the other is depressed, and convention is that the rudder rotates in the same direction as the arm connecting the two rudder pedals. For example, if a pilot presses the left rudder pedal forward, rotating the arm clockwise, the rudder will also rotate clockwise, deflecting airflow at the tail to the left and yawing the plane to the left. Similarly, if the pilot presses the right rudder pedal forward, the plane will yaw to the right (cf. "tiller orders"). In aircraft with duplicate control systems (such as trainer aircraft, transport aircraft and airliners), for example with fly-by-wire, the pedal sets of both pilots are linked together so that the other pilot can ...

Pedals (The Nottingham Cycling Campaign)
Pedals is a voluntary organisation founded in 1979 to encourage more people to use bicycles and to campaign for safer and more attractive conditions for cyclists in the Nottingham area. Pedals campaigned to get Nottingham one of the country's largest network of urban cycle routes in the 1980s. It continues to press for many more facilities, especially in and across the Nottingham City Centre, City Centre and the north side of Nottingham, as well as linking better to nearby countryside. Strategic Vision The group describes its strategy as follows: "''Pedals wishes to see support for cycling in 3 ways:'' ''- Promotion of cycling as a healthy and sustainable means of transport including:-'' ''- Improvement of existing infrastructure to make cycling safer'' ''- Expansion of specific facilities for cyclists''" Campaigns Pedals actively engaged with Nottingham Express Transit (NET) during the developments of phase one and two to push for better provision for cyclists, including cycle ...

Car Controls
Car controls are the components in automobiles and other powered road vehicles, such as trucks and buses, used for driving and parking. While controls like steering wheels and pedals have existed since the invention of cars, other controls have developed and adapted to the demands of drivers. For example, manual transmissions became less common as technology relating to automatic transmissions became advanced. Earlier versions of headlights and signal lights were fueled by acetylene or oil. Acetylene was preferred to oil, because its flame is resistant to both wind and rain. Acetylene headlights, which gave a strong green-tinted light, were popular until after World War I; even though the first electric headlights were introduced in 1898 (and those were battery-powered), it wasn't until high-wattage bulbs and more powerful car electrical generating systems were developed in the late 1910s that electric lighting systems entirely superseded acetylene.

Pedalo
A pedalo (British English), pedal boat (U.S. English), or paddle boat (U.S., Canadian, and Australian English) is a human-powered watercraft propelled by the action of bicycle pedal, pedals turning a paddle wheel. Description A pedalo is a human-powered watercraft propelled by the turning of a paddle wheel. The wheel is turned by people operating the wiktionary:Pedal, pedals of the craft. The paddle wheel of a pedalo is a smaller version of that used by a paddle steamer. Use Pedalos, being particularly suited to calm waters, are often hired out for use on ponds and small lakes in urban parks, as well as in beaches when the weather allows. Designs The earliest record of a pedalo is perhaps Leonardo da Vinci's diagram of a craft driven by two pedals. Typically, a two-seat pedalo has two sets of pedals side-by-side, designed to be used together. Some models, however, have three pedals on each side, to allow a person boating alone to pedal from a centrally seated position. ...
