A gear or cogwheel is a rotating machine part having cut teeth, or cogs, which mesh with another toothed part to transmit torque, in most cases with teeth on the one gear being of identical shape, and often also with that shape on the other gear. Two or more gears working in a sequence (train) are called a gear train or, in many cases, a transmission; such gear arrangements can produce a mechanical advantage through a gear ratio and thus may be considered a simple machine. Geared devices can change the speed, torque, and direction of a power source. The most common situation is for a gear to mesh with another gear; however, a gear can also mesh with a linear toothed part, called a rack, thereby producing translation instead of rotation.
The gears in a transmission are analogous to the wheels in a crossed belt pulley system. An advantage of gears is that the teeth of a gear prevent slippage.
When two gears mesh, and one gear is bigger than the other (even though the size of the teeth must match), a mechanical advantage is produced, with the rotational speeds and the torques of the two gears differing in an inverse relationship.
Spur is a feature on Earth's Moon, a crater in the Hadley–Apennine region. Astronauts David Scott and James Irwin visited it in 1971, on the Apollo 15 mission, during EVA 2. Spur was designated Geology Station 7.
Spur is located on the north slope of Mons Hadley Delta, about 200 m above the plain to the north. It is east of the much larger St. George crater, and about 5 km south of the Apollo 15 landing site itself.
The astronauts found the "Genesis Rock", sample 15415, at Spur. The sample contains a large clast of anorthosite, and Dave Scott said "Guess what we just found! I think we found what we came for" as he examined the sample. They also found samples 15445 and 15455, so-called black and white breccias, which are thought to be impact melt breccia resulting from the Imrbrium basin impact event.
The crater was named by the astronauts, and the name was formally adopted by the IAU in 1973.

Typeface anatomy describes the graphic elements that make up printed letters in a typeface.
The strokes of a letter are the lines that make it up. Strokes may be straight, as in k l v w x z, or curved, as in c o s. If straight, they may be horizontal, vertical, or diagonal; if curved, open or closed. Typographers also speak of an instroke, where one starts writing the letter, as at the top of a c f, and an outstroke, where the pen leaves off, as at the bottom of c e j k t y.
Typefaces are born from the struggle between rules and results. Squeezing a square about 1% helps it look more like a square; to appear the same height as a square, a circle must be measurably taller. The two strokes in an X aren't the same thickness, nor are their parallel edges actually parallel; the vertical stems of a lowercase alphabet are thinner than those of its capitals; the ascender on a d isn't the same length as the descender on a p, and so on. For the rational mind, type design can be a maddening game of drawing things differently in order to make them appear the same.
A spur route is a usually short road forming a branch from a longer, more important route (typically a major road, freeway, Interstate Highway, or motorway). A bypass or beltway is never considered a true spur route as it typically reconnects with another or the same major road. Both loops and spurs can be forms of special route.
In the province of Ontario, most spur routes are designated as A or B, such as Highway 17A, or 7B. A stands for "Alternate Route", and usually links a highway to a town's central core or main attraction, while B stands for "Business Route" or "Bypass", but are used when a main highway is routed around a town and away from its former alignment. The designation of "C" was used twice (Highway 3C and 40C), and is assumed to mean "Connector". Both highways have long since been retired and are now county roads. There was also one road with the D designation (Highway 8D, later the original Highway 102), and this may have stood for "Diversion", as it was along the first completed divided highway in Canada at the time (Cootes Drive in Hamilton).

Gear (real name: I.Z.O.R.) is a fictional character a superhero in the DC Comics universe. The character is a member of the Legion of Super-Heroes in the future.
Gear is a Linsnarian (named for Joseph Michael Linsner?), a race composed of organic machinery beneath humanoid shells. The Blackstar Juvenile Correctional Facility captured him for use in maintaining their systems. For quite some time, he pretended to be servile, while programming some of his machinery to disable the systems keeping the inmates contained and powerless upon his deactivation. On the arrival of the Legionnaire Sensor on the station, he was convinced by her to move prematurely, and was severely damaged in the process, activating his failsafes.
However, Brainiac 5 successfully repaired him, and Gear remained on the Legion Outpost space station until most of the Legion was lost in a rift and the team was forcefully disbanded as a result. R.J. Brande then made contact with many of the remaining Legionnaires, including Gear, and put together a plan to construct a "Legion World" - an artificial planetoid to house a revived and expanded team, which Gear and Invisible Kid designed and helped to construct.
Gear is a six-issue comic book limited series written and illustrated by Doug TenNapel. It was published in six issues by Fireman Press Ltd, a production company and publishing house. The issues were reprinted in trade paperback form by Image Comics in 2007. Many of the characters presented in the book were retooled for TenNapel's Nickelodeon cartoon series Catscratch.
Gear featured black-and-white artwork mostly created with an ink brush by TenNapel. Many of its covers were photos of 3D sculptures, owing to TenNapel's affinity for stop motion animation. The Image Comics collection presents the artwork in full color.
Gear tells the story of a podunk town of squat, hominid-like cats who are bordered on all sides by bigger and more war-like animals. The town's only protection comes from an aged Guardian, a gigantic battle robot in disrepair. The town elder sends four brave cats out to capture an enemy guardian to further defend the town. The cats are named Waffle, Mr. Black, Simon and Gordon. They were named after TenNapel's actual pet cats. After tragedy strikes the cats in a battle with the neighboring dog faction's Guardian, Waffle begins blaming himself for the trouble and goes into the woods to end his own life. There he meets Chee, an insect from another warring faction. The two befriend each other, little knowing of the role they will both play in the oncoming battles.
