Leonardo's Self-propelled Cart
Leonardo's self-propelled cart is an invention designed by Leonardo da Vinci, considered the ancestor of the modern automobile. Info The machine is powered by two symmetric springs. While one spring would be enough to move the device, two symmetric springs probably looked like a more "logically perfect" solution. Leonardo had been well aware that the powering force provided by the springs drops significantly when they unwind. In order to deliver smooth and stable motion, the machine features a balance wheel, as used in clocks. The control mechanism is quite complex and allows it to follow a pre-programmed path automatically. The machine also features a mechanism similar to a differential that in addition allows the turning angle to be set. A replica of the self-propelled cart is kept at the museum Clos Lucé, near Château d'Amboise, in France. The television show ''Doing DaVinci'' also made a replica in 2009.

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. While his fame initially rested on his achievements as a painter, he also became known for #Journals and notes, his notebooks, in which he made drawings and notes on a variety of subjects, including anatomy, astronomy, botany, cartography, painting, and paleontology. Leonardo is widely regarded to have been a genius who epitomized the Renaissance humanism, Renaissance humanist ideal, and his List of works by Leonardo da Vinci, collective works comprise a contribution to later generations of artists matched only by that of his younger contemporary, Michelangelo. Born Legitimacy (family law), out of wedlock to a successful Civil law notary, notary and a lower-class woman in, or near, Vinci, Tuscany, Vinci, he was educated in Florence by the Italian painter and sculptor ...

Automobile
A car or automobile is a motor vehicle with wheels. Most definitions of ''cars'' say that they run primarily on roads, seat one to eight people, have four wheels, and mainly transport people instead of goods. The year 1886 is regarded as the birth year of the car, when German inventor Carl Benz patented his Benz Patent-Motorwagen. Cars became widely available during the 20th century. One of the first cars affordable by the masses was the 1908 Model T, an American car manufactured by the Ford Motor Company. Cars were rapidly adopted in the US, where they replaced animal-drawn carriages and carts. In Europe and other parts of the world, demand for automobiles did not increase until after World War II. The car is considered an essential part of the developed economy. Cars have controls for driving, parking, passenger comfort, and a variety of lights. Over the decades, additional features and controls have been added to vehicles, making them progressively more com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Balance Wheel
A balance wheel, or balance, is the timekeeping device used in mechanical watches and small clocks, analogous to the pendulum in a pendulum clock. It is a weighted wheel that rotates back and forth, being returned toward its center position by a spiral torsion spring, known as the balance spring or ''hairspring''. It is driven by the escapement, which transforms the rotating motion of the watch gear train into impulses delivered to the balance wheel. Each swing of the wheel (called a "tick" or "beat") allows the gear train to advance a set amount, moving the hands forward. The balance wheel and hairspring together form a harmonic oscillator, which due to resonance oscillates preferentially at a certain rate, its resonant frequency or "beat", and resists oscillating at other rates. The combination of the mass of the balance wheel and the elasticity of the spring keep the time between each oscillation or "tick" very constant, accounting for its nearly universal use as the ...

Differential (mechanical Device)
A differential is a gear train with three drive shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others, or a fixed multiple of that average. Functional description The following description of a differential applies to a traditional rear-wheel-drive car or truck with an open or limited slip differential combined with a reduction gearset using bevel gears (these are not strictly necessary; see spur-gear differential): Thus, for example, if the car is making a turn to the right, the main ring gear may make 10 full rotations. During that time, the left wheel will make more rotations because it has farther to travel, and the right wheel will make fewer rotations as it has less distance to travel. The sun gears (which drive the axle half-shafts) will rotate at different speeds relative to the ring gear (one faster, one slower) by, say, 2 full turns each (4 full turns relative to each other), resulting in the left wheel ma ...

Clos Lucé
The Château du Clos Lucé (or simply Clos Lucé), formerly called Manoir du Cloux, is a large château located in the center of Amboise, in the department of Indre-et-Loire, in the Centre-Val de Loire region of France. It is located in the natural Val de Loire (formerly called Touraine) region. Built by Hugues d'Amboise in 1471, the palace has known several famous owners such as the French king Charles VIII and Leonardo da Vinci. Clos Lucé is 500 metres from the royal Château d'Amboise, to which it is connected by an underground passageway. King Charles VIII bought the home from Etienne Le Loup in 1490 and during this time it became known as the ‘summer house’, housing French royalty. After a few decades Francis I gave it to Leonardo da Vinci when he invited him to live in France in 1516. The aging polymath lived his last years in this house, until his death on 2 May 1519. Thanks to its famous owners, this house today ranks as a ‘historical monument’ and therefore is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Château D'Amboise
The Château d'Amboise is a château in Amboise, located in the Indre-et-Loire ''département'' of the Loire Valley in France. Confiscated by the monarchy in the 15th century, it became a favoured royal residence and was extensively rebuilt. King Charles VIII died at the château in 1498 after hitting his head on a door lintel. The château fell into decline from the second half of the 16th century and the majority of the interior buildings were later demolished, but some survived and have been restored, along with the outer defensive circuit of towers and walls. It has been recognised as a '' monument historique'' by the French Ministry of Culture since 1840. History Origins The Château d'Amboise was built on a spur above the river Loire. The strategic qualities of the site were recognised before the medieval construction of the castle, and a Gallic oppidum was built there. In the late 9th century Ingelgarius was made viscount of Orléans and through his mother was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Science And Inventions Of Leonardo Da Vinci
Leonardo da Vinci (1452–1519) was an Italian polymath, regarded as the epitome of the "Renaissance Man", displaying skills in numerous diverse areas of study. Whilst most famous for his paintings such as the ''Mona Lisa'' and the ''Last Supper'', Leonardo is also renowned in the fields of civil engineering, chemistry, geology, geometry, hydrodynamics, mathematics, mechanical engineering, optics, physics, pyrotechnics, and zoology. While the full extent of his scientific studies has only become recognized in the last 150 years, during his lifetime he was employed for his engineering and skill of invention. Many of his designs, such as the movable dikes to protect Venice from invasion, proved too costly or impractical. Some of his smaller inventions entered the world of manufacturing unheralded. As an engineer, Leonardo conceived ideas vastly ahead of his own time, conceptually inventing the parachute, the helicopter, an armored fighting vehicle, the use of concentrated solar power ...
