Carousel
A carousel or carrousel (mainly North American English), merry-go-round (international), roundabout (British English), or hurdy-gurdy (an old term in Australian English, in SA) is a type of amusement ride consisting of a rotating circular platform with seats for riders. The "seats" are traditionally in the form of rows of wooden horses or other animals mounted on posts, many of which are moved up and down by gears to simulate galloping, to the accompaniment of looped circus music. Carousels are commonly populated with horses, each horse weighing roughly 100 lbs (45 kg), but may include a variety of mounts, for example pigs, zebras, tigers, or mythological creatures such as dragons or unicorns. Sometimes, chair-like or bench-like seats are used, and occasionally mounts can be shaped like aeroplanes or cars. The names ''carousel'' and ''merry-go-round'' are also used, in varying dialects, to refer to a distinct piece of playground equipment. History Early carou ...

Roundabout (play)
A roundabout (British English), merry-go-round (American English), or carousel (Australian English) is piece of playground equipment, a flat disk, frequently about in diameter, with bars on it that act as both hand-holds and something to lean against while riding. The disk can be made to spin by pushing or pulling on its handles, either by running around the outside, or by pulling and re-grabbing as it spins, from a stationary stance. If the disk is mounted at a tilt to the ground, after an initial push, the disk can be speeded up without further pushing or touching the ground. The trick is to have the rider(s) lean into the center of the disk while ascending and leaning out from the center when descending. It is the physics of Angular Momentum and also works for swings. Often found in school playgrounds and public parks, they offer riders (typically children) a dizzying ride when either others spin the wheel, or by spinning it themselves by running around it, and then jumping ...

Amusement Ride
Amusement rides, sometimes called carnival rides, are mechanical devices or structures that move people especially kids to create fun and enjoyment. Rides are often perceived by many as being scary or more dangerous than they actually are. This could be due to the design or from hearing about accidents involving rides that are similar. They are expected at most annual events such as fairs, traveling carnivals, and circuses around the world. Sometimes music festivals and concerts also host amusement park rides. Types of rides * Flat rides are usually considered to be those that move their passengers in a plane generally parallel to the ground, such as rides that spin around a vertical axis, like carousels and twists, and ground level rides such as bumper cars and The Whip. * Gravity rides are those where gravity is responsible for all or some of the movement, and where any vertical movement is not about a fixed point, such as roller coasters, water slides, and drop towers. ...

Rotation
Rotation, or spin, is the circular movement of an object around a '' central axis''. A two-dimensional rotating object has only one possible central axis and can rotate in either a clockwise or counterclockwise direction. A three-dimensional object has an infinite number of possible central axes and rotational directions. If the rotation axis passes internally through the body's own center of mass, then the body is said to be ''autorotating'' or '' spinning'', and the surface intersection of the axis can be called a '' pole''. A rotation around a completely external axis, e.g. the planet Earth around the Sun, is called ''revolving'' or ''orbiting'', typically when it is produced by gravity, and the ends of the rotation axis can be called the '' orbital poles''. Mathematics Mathematically, a rotation is a rigid body movement which, unlike a translation, keeps a point fixed. This definition applies to rotations within both two and three dimensions (in a plane and in spa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jousting
Jousting is a martial game or hastilude between two horse riders wielding lances with blunted tips, often as part of a tournament. The primary aim was to replicate a clash of heavy cavalry, with each participant trying to strike the opponent while riding towards him at high speed, breaking the lance on the opponent's shield or jousting armour if possible, or unhorsing him. The joust became an iconic characteristic of the knight in Romantic medievalism. The participants experience close to three and a quarter times their body weight in G-forces when the lances collide with their armour. The term is derived from Old French , ultimately from Latin "to approach, to meet". The word was loaned into Middle English around 1300, when jousting was a very popular sport among the Anglo-Norman knighthood. The synonym tilt (as in tilting at windmills) dates . Jousting is based on the military use of the lance by heavy cavalry. It transformed into a specialized sport during the Late Mi ...

Germany
Germany,, officially the Federal Republic of Germany, is a country in Central Europe. It is the second most populous country in Europe after Russia, and the most populous member state of the European Union. Germany is situated between the Baltic and North seas to the north, and the Alps to the south; it covers an area of , with a population of almost 84 million within its 16 constituent states. Germany borders Denmark to the north, Poland and the Czech Republic to the east, Austria and Switzerland to the south, and France, Luxembourg, Belgium, and the Netherlands to the west. The nation's capital and most populous city is Berlin and its financial centre is Frankfurt; the largest urban area is the Ruhr. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity. A region named Germania was documented before AD 100. In 962, the Kingdom of Germany formed the bulk of the Holy Roman Empire. During the 16th ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centrifugal Force
In Newtonian mechanics, the centrifugal force is an inertial force (also called a "fictitious" or "pseudo" force) that appears to act on all objects when viewed in a rotating frame of reference. It is directed away from an axis which is parallel to the axis of rotation and passing through the coordinate system's origin. If the axis of rotation passes through the coordinate system's origin, the centrifugal force is directed radially outwards from that axis. The magnitude of centrifugal force ''F'' on an object of mass ''m'' at the distance ''r'' from the origin of a frame of reference rotating with angular velocity is: F = m\omega^2 r The concept of centrifugal force can be applied in rotating devices, such as centrifuges, centrifugal pumps, centrifugal governors, and centrifugal clutches, and in centrifugal railways, planetary orbits and banked curves, when they are analyzed in a rotating coordinate system. Confusingly, the term has sometimes also been used for the re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tuileries Palace
The Tuileries Palace (french: Palais des Tuileries, ) was a royal and imperial palace in Paris which stood on the right bank of the River Seine, directly in front of the Louvre. It was the usual Parisian residence of most French monarchs, from Henry IV to Napoleon III, until it was burned by the Paris Commune in 1871. Built in 1564, it was gradually extended until it closed off the western end of the Louvre courtyard and displayed an immense façade of 266 metres. Since the destruction of the Tuileries, the Louvre courtyard has remained open and the site is now the location of the eastern end of the Tuileries Garden, forming an elevated terrace between the Place du Carrousel and the gardens proper. History Plan of Catherine de Medici (16th C.) The site of the Tuileries palace was originally just outside the walls of the city, in an area frequently flooded by the Seine as far as the present Rue Saint-Honore. The land was occupied by the workshops and kilns craftsmen who ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Knight
A knight is a person granted an honorary title of knighthood by a head of state (including the Pope) or representative for service to the monarch, the church or the country, especially in a military capacity. Knighthood finds origins in the Greek ''hippeis'' and ''hoplite'' (ἱππεῖς) and Roman '' eques'' and ''centurion'' of classical antiquity. In the Early Middle Ages in Europe, knighthood was conferred upon mounted warriors. During the High Middle Ages, knighthood was considered a class of lower nobility. By the Late Middle Ages, the rank had become associated with the ideals of chivalry, a code of conduct for the perfect courtly Christian warrior. Often, a knight was a vassal who served as an elite fighter or a bodyguard for a lord, with payment in the form of land holdings. The lords trusted the knights, who were skilled in battle on horseback. Knighthood in the Middle Ages was closely linked with horsemanship (and especially the joust) from its origins in the 12 ...

Place Du Carrousel
The Place du Carrousel () is a public square in the 1st arrondissement of Paris, located at the open end of the courtyard of the Louvre Palace, a space occupied, prior to 1883, by the Tuileries Palace. Sitting directly between the museum and the Tuileries Garden, the Place du Carrousel delineates the eastern end of the gardens just as the Place de la Concorde defines its western end. The name "carrousel" refers to a type of military dressage, an equine demonstration now commonly called ''military drill''. The Place du Carrousel was named in 1662, when it was used for such a display by Louis XIV. History On 5 October 1789, a mob from Paris descended upon Versailles and forced the royal family — Louis XVI, Marie Antoinette, and their children, along with the comte de Provence (later king Louis XVIII), his wife, and Madame Elisabeth, the youngest sister of the king — to move to Paris under the watchful eye of the Garde Nationale. The king and queen were installed in the Tu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
