Rowing Cycle
A rowing cycle is a wheeled vehicle propelled by a rowing motion of the body. Steering, braking, and shifting are usually done by the handlebars. Feet are on symmetrical foot rests, as opposed to rotating pedals. Unlike many rowing boats, the rider faces forward. Rowing cycles exist in numerous designs, particularly with respect to frames and drive mechanisms. Commercial production numbers for rowing cycles are small compared to that of standard bicycles. History The use of a rowing-like action to propel a land vehicle goes probably to the 1870s, as George W. Lee used a sliding-seat in a tricycle. Roadsculler races were held in Madison Square Garden in the 1880s. A toy catalog from FAO Schwarz in 1911 advertised a four-wheeled "Row-Cycle" for children, operated using two levers in a standing position and with steering done by the feet. In the 1920s, Manfred Curry in Germany designed and constructed the Landskiff ("land boat"), a four-wheeled vehicle that would be known as a R ...

Bungee Cord
file:Bungee Cord PICT6882a.jpg, Bungee cords equipped with metal hooks A bungee cord (sometimes spelled bungie; also known as a shock cord or an ocky strap) is an elastomer, elastic cord composed of one or more elastic strands forming a core, usually covered in a woven cotton or polypropylene sheath. The sheath does not materially extend elastically, but it is braided with its strands spiraling around the core so that a longitudinal pull causes it to squeeze the core, transmitting the core's elastic compression to the longitudinal extension of the sheath and cord. Specialized bungees, such as some used in bungee jumping, may be made entirely of elastic strands.

Handcar
A handcar (also known as a pump trolley, pump car, rail push trolley, push-trolley, jigger, Kalamazoo, velocipede, gandy dancer cart, platelayers' cart, draisine, or railbike) is a railroad car powered by its passengers or by people pushing the car from behind. It is mostly used as a railway maintenance of way or mining car, but it was also used for passenger service in some cases. Design and function A typical design consists of an arm, called the walking beam, that pivots seesaw-like on a base, which the passengers alternately push down and pull up to move the car. An even simpler design is pushed by two or four people (called trolleymen), with hand brakes to stop the trolley. When the trolley slows down, two trolleymen jump off the trolley and push it till it picks up speed. Then they jump into the trolley again, and the cycle continues. The trolleymen take turns in pushing the trolley to maintain the speed and avoid fatigue. Four people also required to safely lift the t ...

Outline Of Cycling
Cycling, also known as bicycling or biking, is the activity of riding bicycles or other Human-powered transport, human-powered vehicles with Wheel, wheels, for transportation, recreation, exercise, sport, and other purposes. People who engage in cycling are called cyclists, bikers, or bicyclists. They may wear everyday clothing suited to their destination or specialized cycling attire, sometimes carrying an additional set of clothes. Cycling includes not only traditional two-wheeled bicycles but also unicycles, tricycles, quadricycles, and other human-powered transport, human-powered vehicles (HPVs). Some bicycles are equipped with Electric motor, electric motors (e-bikes) or other forms of Motorized bicycle, motor assistance. Cycling can be done individually or with others. Passengers may ride in front,for instance in the box of a cargo bike, sit on a luggage carrier, or use specially designed seats for children or pets. Some bicycles, such as tandem bicycles or multi-rider pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indoor Rower
An indoor rower, or rowing machine, is a machine used to simulate the action of watercraft rowing for the purpose of exercise or training for rowing. Modern indoor rowers are known as ergometers (colloquially erg or ergo) because they measure work performed by the rower (that can be measured in ergs). Indoor rowing has become established as a sport, drawing a competitive environment from around the world. The term "indoor rower" also refers to a participant in this sport. History Chabrias, an Athenian admiral of the 4th century BC, introduced the first rowing machines as supplemental military training devices. "To train inexperienced oarsmen, Chabrias built wooden rowing frames onshore where beginners could learn technique and timing before they went onboard ship." Early rowing machines are known to have existed from the mid-1800s, a US patent being issued to W.B. Curtis in 1872 for a particular hydraulic-based damper design. Machines using linear pneumatic resistance were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Handcycle
A handcycle is a type of human-powered land vehicle powered by the arms rather than the Human leg, legs, as on a bicycle. Most handcycles are tricycle in form, with two coasting rear Bicycle wheel, wheels and one steerable powered front wheel. Despite usually having three wheels, they are also known as ''handbikes''. History Stephan Farffler was a Nuremberg watchmaker of the seventeenth century whose invention of a manumotive carriage in 1655 is widely considered to have been the first self-propelled bicycle. He is believed to have been either a Paraplegia, paraplegic or an Amputation, amputee. The three-wheeled device is believed to have been a precursor to the modern-day tricycle and bicycle. Later innovations in handcycle design would be driven by a need to provide transportation for soldiers injured during the American Civil War, and later, the First World War. While Farffler's carriage emerged from his background as a clockmaker, mid-nineteenth century designs would be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tandem
Tandem, or in tandem, is an arrangement in which two or more animals, machines, or people are lined up one behind another, all facing in the same direction. ''Tandem'' can also be used more generally to refer to any group of persons or objects working together, not necessarily in line. The English word ''tandem'' derives from the Latin adverb , meaning ''at length'' or ''finally''. It is a word play, using the Latin phrase (referring to time, not position) for English "at length, lengthwise". Horse driving When Driving (horse), driving horses, ''tandem'' refers to one horse harnessed in front of another to pull a load or Horse-drawn vehicle, vehicle. A tandem arrangement provides more pulling power than a single horse, such as for pulling a heavy load up a steep hill, out of heavy mud or snow, or pulling heavy loads on narrow tracks or through narrow gates and doorways (too wide for a pair of horses side-by-side). For example, a Brewer's van fully loaded with 25 barrels migh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railroad
Rail transport (also known as train transport) is a means of transport using wheeled vehicles running in railway track, tracks, which usually consist of two parallel steel railway track, rails. Rail transport is one of the two primary means of land transport, next to road transport. It is used for about 8% of passenger and rail freight transport, freight transport globally, thanks to its Energy efficiency in transport, energy efficiency and potentially high-speed rail, high speed.Rolling stock on rails generally encounters lower friction, frictional resistance than rubber-tyred road vehicles, allowing rail cars to be coupled into longer trains. Power is usually provided by Diesel locomotive, diesel or Electric locomotive, electric locomotives. While railway transport is capital intensity, capital-intensive and less flexible than road transport, it can carry heavy loads of passengers and cargo with greater energy efficiency and safety.

Quadracycle (human-powered Vehicle)
A quadracycle (also spelled quadricycle) is a four-wheeled human-powered land vehicle. It is also referred to as a quadcycle, pedal car or four-wheeled bicycle amongst other terms. Quadracycles have been in use since 1853 and have grown into several families of vehicles for a variety of purposes, including tourist rentals, pedal taxis, private touring, mountain and industrial use. Nomenclature There is no consensus amongst manufacturers of four-wheeled, human-powered vehicles as to what this class of vehicles should be called, although ''quadracycle'' is the most commonly used term. Manufacturers who do refer to their products by class of vehicle call them: *Quadracycle - 11 manufacturers *Four-wheel bicycle - 7 manufacturers *Quadricycle - 5 manufacturers *Quadcycle - 3 manufacturers *Pedal car - 2 manufacturers *Quad - 2 manufacturers In addition there are single manufacturers who call them Go-kart, Car, Car-Bike, Ecological car, Human Powered Vehicle, Pedal Kart, Quadri ...

Tricycle
A tricycle, sometimes abbreviated to trike, is a Human-powered transport, human-powered (or gasoline or electric motor powered or assisted, or gravity powered) Three-wheeler, three-wheeled vehicle. Some tricycles, such as cycle rickshaws (for passenger transport) and freight trikes, are used for commercial purposes, especially in the developing world, particularly Africa and Asia. In the West, adult-sized tricycles are used primarily for recreation, shopping, and exercise. Tricycles are favoured by children, the disabled, and senior adults for their apparent stability versus a bicycle; however a Three-wheeler#Two rear, conventional trike may exhibit poor dynamic lateral stability, and the rider should exercise appropriate operating caution when cornering (e.g., with regard to speed, rate of turn, slope of surface) and operating technique (e.g., leaning the body 'into' the turn) to avoid tipping the trike over. Designs such as recumbents or others which place the rider lower relat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fusee (horology)
A fusee (from the French ''fusée'', wire wound around a spindle) is a cone (geometry), cone-shaped pulley with a helical groove around it, wound with a cord or chain attached to the mainspring Barrel (horology), barrel of antique mechanical watches and clocks. It was used from the 15th century to the early 20th century to improve timekeeping by equalizing the uneven pull of the mainspring as it ran down. The watch and clock historian Granville Hugh Baillie stated of the fusee, "Perhaps no problem in mechanics has ever been solved so simply and so perfectly." History The origin of the fusee is not known. Many sources erroneously credit clockmaker Jacob Zech of Prague with inventing it around 1525. The earliest definitely dated fusee clock was made by Zech in 1525, but the fusee actually appeared earlier, with the first spring driven clocks in the 15th century., p.127-128, p.121 The idea probably did not originate with clockmakers, since the earliest known example is in a cross ...
