Comprehensive Analysis

1) "Metal" -- As to metal gears 1met·al Pronunciation: 'me-t&l Function: noun Usage: often attributive Etymology: Middle English, from Anglo-French, from Latin metallum mine, metal, from Greek metallon 1 : any of various opaque, fusible, ductile, and typically lustrous substances that are good conductors of electricity and heat, form cations by loss of electrons, and yield basic oxides and hydroxides; especially : one that is a chemical element as distinguished from an alloy 2 a : METTLE 1a b : the substance out of which a person or thing is made 3 : glass in its molten state 4 a : printing type metal b : matter set in metal type 5 : ROAD METAL 6 : HEAVY METAL Pronunciation Symbols Hot metal work from a blacksmith In chemistry, a metal (Greek: Metallon) is an element that readily forms positive ions (cations) and has metallic bonds. Metals are sometimes described as a lattice of positive ions surrounded by a cloud of delocalized electrons. The metals are one of the three groups of elements as distinguished by their ionization and bonding properties, along with the metalloids and nonmetals. On the periodic table, a diagonal line drawn from boron (B) to polonium (Po) separates the metals from the nonmetals. Most elements on this line are metalloids, sometimes called semi-metals; elements to the lower left are metals; elements to the upper right are nonmetals. A modern definition of metals is that they have overlapping conduction bands and valence bands in their electronic structure. This definition opens up the category for metallic polymers and other organic metals, which have been made by researchers and employed in high-tech devices. These synthetic materials often have the characteristic silvery-grey reflectiveness (luster) of elemental metals. The traditional definition focuses on the bulk properties of metals. They tend to be lustrous, ductile, malleable, and good conductors of electricity, while nonmetals are generally brittle (if solid), lack luster, and are insulators. 1 Chemical properties 2 Physical properties 3 Alloys 4 Categories 4.1 Base metal 4.2 Ferrous metal 4.3 Noble metal 4.4 Precious metal 5 Extraction 6 Metallurgy 7 Applications 8 Astronomy 9 See also 10 External link Most metals are chemically reactive, reacting with oxygen in the air to form oxides over varying timescales (for..." 2) "Gears" -- As to metal gears 1gear Pronunciation: 'gir Function: noun Etymology: Middle English gere, from Old Norse gervi, gorvi; akin to Old English gearwe equipment, clothing, gearu ready -- more at YARE 1 a : CLOTHING, GARMENTS b : movable property : GOODS 2 : EQUIPMENT, PARAPHERNALIA <fishing gear> 3 a : the rigging of a ship or boat b : the harness especially of horses 4 dialect chiefly British : absurd talk : NONSENSE 5 dialect chiefly British : DOINGS 6 a (1) : a mechanism that performs a specific function in a complete machine <steering gear> (2) : a toothed wheel (3) : working relation, position, order, or adjustment <got her career in gear> (4) : a level or pace of functioning <kicked their performance into high gear> b : one of two or more adjustments of a transmission (as of a bicycle or motor vehicle) that determine mechanical advantage, relative speed, and direction of travel - gear·less /-l&s/ adjective [gear illustration] Pronunciation Symbols Spur gears found on a piece of farm equipment A gear wheel is a wheel with teeth around its circumference, the purpose of the teeth being to mesh with similar teeth on another mechanical device -- possibly another gear wheel -- so that force can be transmitted between the two devices in a direction tangential to their surfaces. A non-toothed wheel can transmit some tangential force but will slip if the force is large; teeth prevent slippage and allow the transmission of large forces. A gear can mesh with any device having teeth compatible with the gear's teeth. Such devices include racks and other non-rotating devices; however, the most common situation is for a gear to be in mesh with another gear. In this case rotation of one of the gears necessarily causes the other gear to rotate. In this way, rotational motion can be transferred from one location to another (that is, from one shaft to another). While gears are sometimes used simply for this reason -- to transmit rotation to another shaft -- perhaps their most important feature is that, if the gears are of unequal sizes (diameters), a mechanical advantage is also achieved, so that the rotational speed, and torque (rotational force), of the second gear are different from that of the first. In this way, gears provide a means of increasing or decreasing a rotational speed, or a torque. This is a highly useful property. 1 General 1.1 Mechanical advantage 1.2 Comparison with other drive mechanisms 2 Spur gears 3 Helical gears 4 Double helical gears 5 Bevel gears 5.1 Crown gear 6 Hypoid gears 7 Worm gear 8 Sector gear 9 Rack and pinion 9.1 See also 10 Gear Nomenclature Further Data On Term for metal gears Internet users who seek metal gears often also seach for: metal patina, metal in, metal frames, fabricated metal, metal plate, metal planters, metal lathe, metal bed, sheet metal fabrications, metal wastebasket, metal, canopy, metal, bed, frames, metallic, silver, metal, hydride, metal, gears, metal, gears, metal, decor, metal, conduit, metal, patina, metal, metal, patina, metal, in, metal, frames, fabricated, metal, metal, plate, metal, planters, metal, lathe, metal, bed, sheet, metal, fabrications, metal, wastebasket Regularly Occuring Typos with metal gears include: emtal mteal meatl metla etal mtal meal metl meta netal jetal ketal mwtal mstal mdtal mrtal matal mital motal mutal meral mefal megal meyal metql metsl metzl metel metil metol metul metak metao metap egars gaers geras geasr ears gars gers geas gear tears fears vears bears hears jears gwars gsars gdars grars gaars giars goars guars geqrs gesrs gezrs geers geirs geors geurs geaes geads geafs geats geara gearw geard gearx gearz Commonly appearing connections are : micro atx, michelin tire, michelin map, michael jordan shoes, miata spec, miami tv, miami school, mexico guanajuato, metric halo, metallic silver, metal hydride, metal decor, metal conduit, metal, messenger pop up, message therapist, merino wool sweater, mercury parts, mercury chelation, mercedes service, mercedes benz 280se, mens thong swimwear Similar searches have yielded these phrases metal gears: metal canopy, metal bed frames, metallic silver, metal hydride, metal gears, metal gears, metal decor, metal conduit, metal, patina metal Certain copy here metal gears made available through Wikipedia and the GNU Free Documentation License.
