Mechanical Toy
Mechanical toys are toys powered by mechanical energy. Depending on the mechanism used they can perform a range of motions, from simple to very complex. Types The types of mechanical energy used to power mechanical toys include rubber bands, springs, and flywheels. Mechanical toys use 4 types of different movements, rotary (going around in a circle), linear (moving in a straight line then stopping), reciprocating (moving backwards and forwards continuously in a straight line) and oscillating (moving backwards and forwards in a curve). Mechanical toys use several types of mechanisms, because Cam toys are powered by a very large cam and even bigger cam follower which transfers the cam rotation to the working area of the toy. The cam is ''unevenly'' rotated by placing the rotator out of the ideal center. This transforms the circular motion into motion that moves up and powers the toy. Crank toys are internally based on cams too but allow more complicated motions. Single rotati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gear
A gear is a rotating circular machine part having cut teeth or, in the case of a cogwheel or gearwheel, inserted teeth (called ''cogs''), which mesh with another (compatible) toothed part to transmit (convert) torque and speed. The basic principle behind the operation of gears is analogous to the basic principle of levers. A gear may also be known informally as a cog. Geared devices can change the speed, torque, and direction of a power source. Gears of different sizes produce a change in torque, creating a mechanical advantage, through their ''gear ratio'', and thus may be considered a simple machine. The rotational speeds, and the torques, of two meshing gears differ in proportion to their diameters. The teeth on the two meshing gears all have the same shape. Two or more meshing gears, working in a sequence, are called a gear train or a '' transmission''. The gears in a transmission are analogous to the wheels in a crossed, belt pulley system. An advantage of gears is tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automaton
An automaton (; plural: automata or automatons) is a relatively self-operating machine, or control mechanism designed to automatically follow a sequence of operations, or respond to predetermined instructions.Automaton – Definition and More from the Free Merriam-Webster Dictionary http://www.merriam-webster.com/dictionary/automaton Some automata, such as Jacquemart (bellstriker), bellstrikers in mechanical clocks, are designed to give the illusion to the casual observer that they are operating under their own power. Since long ago, the term is commonly associated with automated puppets that resemble moving humans or animals, built to impress and/or to entertain people. Animatronics are a modern type of automata with electronics, often used for the portrayal of characters in films and in theme park attractions. Etymology The word "automaton" is the latinization of the Ancient Greek , , (neuter) "acting of one's own will". This word was first used by Homer to describe an auto ...

Academy Award
The Academy Awards, better known as the Oscars, are awards for artistic and technical merit for the American and international film industry. The awards are regarded by many as the most prestigious, significant awards in the entertainment industry worldwide. Given annually by the Academy of Motion Picture Arts and Sciences (AMPAS), the awards are an international recognition of excellence in cinematic achievements, as assessed by the Academy's voting membership. The various category winners are awarded a copy of a golden statuette as a trophy, officially called the "Academy Award of Merit", although more commonly referred to by its nickname, the "Oscar". The statuette, depicting a knight rendered in the Art Deco style, was originally sculpted by Los Angeles artist George Stanley from a design sketch by art director Cedric Gibbons. The 1st Academy Awards were held in 1929 at a private dinner hosted by Douglas Fairbanks in The Hollywood Roosevelt Hotel. The Academy Awards cerem ...

European Union
The European Union (EU) is a supranational political and economic union of member states that are located primarily in Europe. The union has a total area of and an estimated total population of about 447million. The EU has often been described as a '' sui generis'' political entity (without precedent or comparison) combining the characteristics of both a federation and a confederation. Containing 5.8per cent of the world population in 2020, the EU generated a nominal gross domestic product (GDP) of around trillion in 2021, constituting approximately 18per cent of global nominal GDP. Additionally, all EU states but Bulgaria have a very high Human Development Index according to the United Nations Development Programme. Its cornerstone, the Customs Union, paved the way to establishing an internal single market based on standardised legal framework and legislation that applies in all member states in those matters, and only those matters, where the states have agreed to act ...

Jacques De Vaucanson
Jacques de Vaucanson (; February 24, 1709 – November 21, 1782) was a French inventor and artist who built the first all-metal lathe which was very important to the Industrial Revolution. The lathe is known as the mother of machine tools, as it was the first machine tool that led to the invention of other machine tools. He was responsible for the creation of impressive and innovative automata. He also was the first person to design an automatic loom. Early life De Vaucanson was born in Grenoble, France in 1709 as Jacques Vaucanson (the nobiliary particle "de" was later added to his name by the Académie des Sciences). The tenth child of a glove-maker, he grew up poor, and in his youth he reportedly aspired to become a clockmaker. He studied under the Jesuits and later joined the Order of the Minims in Lyon. It was his intention at the time to follow a course of religious studies, but he regained his interest in mechanical devices after meeting the surgeon Claude-Nicolas Le C ...

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 ...

Archytas Of Tarentum
Archytas (; el, Ἀρχύτας; 435/410–360/350 BC) was an Ancient Greek philosopher, mathematician, music theorist, astronomer, statesman, and strategist. He was a scientist of the Pythagorean school and famous for being the reputed founder of mathematical mechanics, as well as a good friend of Plato. Life and work Archytas was born in Tarentum, Magna Graecia and was the son of Mnesagoras or Hadees. For a while, he was taught by Philolaus, and was a teacher of mathematics to Eudoxus of Cnidus. Archytas and Eudoxus' student was Menaechmus. As a Pythagorean, Archytas believed that only arithmetic, not geometry, could provide a basis for satisfactory proofs. Archytas is believed to be the founder of mathematical mechanics.: ''Vitae philosophorum'' As only described in the writings of Aulus Gellius five centuries after him, he was reputed to have designed and built the first artificial, self-propelled flying device, a bird-shaped model propelled by a jet of what was proba ...

Wind-up Toy
A wind-up toy is an automaton toy powered by a clockwork motor. Background Automata built for the sake of art, amusement, and simulation have been described since antiquity, in cases such as Heron of Alexandria designing clockwork birds during the Hellenistic Period. Leonardo da Vinci is frequently credited with constructing a mechanical lion, which he presented to King Francois I in Lyon in 1515. Although no record of the device's original designs remain, a recreation of this piece is housed at the Château du Clos Lucé. Some misinformation exists with regards to Regiomontanus's contribution, and his supposed construction of a flight-capable mechanical eagle and fly, which are frequently credited as the first wind-up toys. This story of an eagle which flew from Nuremberg to greet Friedrich III, alongside that of a fly which could circulate the room before returning to its inventor's hand, was spread by Petrus Ramus after a visit to Nuremberg in 1571, and is apparently false ...

Crank (mechanism)
A crank is an arm attached at a right angle to a rotating shaft by which circular motion is imparted to or received from the shaft. When combined with a connecting rod, it can be used to convert circular motion into reciprocating motion, or vice versa. The arm may be a bent portion of the shaft, or a separate arm or disk attached to it. Attached to the end of the crank by a pivot is a rod, usually called a connecting rod (conrod). The term often refers to a human-powered crank which is used to manually turn an axle, as in a bicycle crankset or a brace and bit drill. In this case a person's arm or leg serves as the connecting rod, applying reciprocating force to the crank. There is usually a bar perpendicular to the other end of the arm, often with a freely rotatable handle or pedal attached. Examples Familiar examples include: Hand-powered cranks * Spinning Wheel * Mechanical pencil sharpener * Fishing reel and other reels for cables, wires, ropes, etc. *Starting ...

Mechanical Energy
In Outline of physical science, physical sciences, mechanical energy is the sum of potential energy and kinetic energy. The principle of conservation of mechanical energy states that if an isolated system is subject only to conservative forces, then the mechanical energy is constant. If an object moves in the opposite direction of a conservative net force, the potential energy will increase; and if the speed (not the velocity) of the object changes, the kinetic energy of the object also changes. In all real systems, however, nonconservative forces, such as frictional forces, will be present, but if they are of negligible Magnitude (mathematics), magnitude, the mechanical energy changes little and its conservation is a useful approximation. In elastic collisions, the kinetic energy is conserved, but in inelastic collisions some mechanical energy may be converted into thermal energy. The equivalence between lost mechanical energy and an increase in temperature was discovered by Jame ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
