Lever
A lever is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or ''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 three types. Also, leverage is mechanical advantage gained in a system. 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. The ratio of the output force to the input force is the mechanical advantage of the lever. As such, the lever is a mechanical advantage device, trading off force against movement. Etymology The word "lever" entered English around 1300 from Old French, in which the word was ''levier''. This sprang from the stem of the verb ''lever'', meaning "to raise". The verb, in turn, goes back to the Latin ''levare'', itself from the adjective ''levis'', meaning "light" (as in "not heavy"). The ...

Player Piano
A player piano (also known as a pianola) is a self-playing piano containing a pneumatic or electro-mechanical mechanism, that operates the piano action via programmed music recorded on perforated paper or metallic rolls, with more modern implementations using MIDI. The rise of the player piano grew with the rise of the mass-produced piano for the home, in the late 19th and early 20th century. Sales peaked in 1924, then declined, as the improvement in phonograph recordings due to electrical recording methods developed in the mid-1920s. The advent of electrical amplification in home music reproduction via radio in the same period helped cause their eventual decline in popularity, and the stock market crash of 1929 virtually wiped out production. History In 1896, Edwin S. Votey invented the first practical pneumatic piano player, called the Pianola. This mechanism came into widespread use in the 20th century, and was all-pneumatic, with foot-operated bellows providing a sour ...

Peddle
A peddler, in British English pedlar, also known as a chapman, packman, cheapjack, hawker, higler, huckster, (coster)monger, colporteur or solicitor, is a door-to-door and/or travelling vendor of goods. 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 difficult to attend town markets. Thus, peddlers played an important role in linking these consumers and regions to wider trade ...

Pedals (bear)
Pedals (died October 2016, New Jersey, United States) was an American black bear (''Ursus americanus'') that walked upright on its hind legs due to 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. Pedals appears to have been killed in October 2016 in New Jersey's first sanctioned bow and arrow hunt in four decades. During the hunt, which also included muzzle-loading rifles, a total of 562 bears were killed. Fame Pedals was first spotted in 2014 in Oak Ridge, New Jersey. The bear walked upright on its hind legs due to injuries on its front paws. The bear's appearance spurred 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 may have been a hoax. Over 300,000 people concerned with Pedals' welfare signed a petition written by Lisa Rose Ru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pedal Bone
The coffin bone, also known as the pedal bone (U.S.), is the bottommost bone in the front and rear legs of horses, cattle, pigs and other ruminants. In horses it is encased by the hoof capsule. Also known as the distal phalanx, third phalanx, or "P3". The coffin bone meets the short pastern bone or second phalanx at the coffin joint. The coffin bone is connected to the inner wall of the horse hoof by a structure called the laminar layer. The insensitive laminae coming in from the hoof wall connects to the sensitive laminae layer, containing the blood supply and nerves, which is attached to the coffin bone. The lamina is a critical structure for hoof health, therefore any injury to the hoof or its support system can in turn affect the coffin bone. Despite the protection provided by the hoof, the coffin bone can be injured and fractured.Vogel (2006), p 189 For example, inflammatory conditions such as laminitis may lead to rotation of the coffin bone and associated permanent dam ...

Rudder Pedal
A conventional fixed-wing aircraft flight control system consists of flight control surfaces, the respective cockpit controls, connecting linkages, and the necessary operating mechanisms to control an aircraft's direction in flight. Aircraft engine controls are also considered as flight controls as they change speed. The fundamentals of aircraft controls are explained in flight dynamics. This article centers on the operating mechanisms of the flight controls. The basic system in use on aircraft first appeared in a readily recognizable form as early as April 1908, on Louis Blériot's Blériot VIII pioneer-era monoplane design. Cockpit controls Primary controls Generally, the primary cockpit flight controls are arranged as follows:Langewiesche, WolfgangStick and Rudder: An Explanation of the Art of Flying McGraw-Hill Professional, 1990, , . * a control yoke (also known as a control column), centre stick or side-stick (the latter two also colloquially known as a control or ...

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 City Centre and the north side of Nottingham, as well as linking better to nearby countryside. Monthly meetings are held at 7.30pm on the third Monday of every month (except public holidays) at the Vat and Fiddle Public House near Nottingham railway station. 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 ...

Automobile Pedal
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) or paddle boat (U.S., Canadian, and Australian English) is a human-powered watercraft propelled by the action of 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 of rotating the 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. Designs The earliest record of a pedalo is perhaps Leonardo da Vinci Leonardo di ser Piero da Vinci (15 April 14522 May 1519) was an Italian polymath of the High Renaissance who was active as a painter, Drawing, draughtsman, engineer, scientist, theorist, sculptor, and architect.
