A cog is a tooth of a gear or cogwheel or the gear itself.
A cog engages with another cog and motion in one will result in motion of the other. Gearwheels that engage with chains are sprockets, not cogs.
Cog, COG, or CoG may also refer to:
Cog was a project at the Humanoid Robotics Group of the Massachusetts Institute of Technology. It was based on the hypothesis that human-level intelligence requires gaining experience from interacting with humans, like human infants do. This in turn required many interactions with humans over a long period. Because Cog's behavior responded to what humans would consider appropriate and socially salient environmental stimuli, the robot was expected to act more human. This behavior also provided the robot with a better context for deciphering and imitating human behavior. This was intended to allow the robot to learn socially, as humans do.
As of 2003, all development of the project had ceased.
Today Cog is retired to the Massachusetts Institute of Technology museum.
A cog (or cog-built vessels) is a type of ship that first appeared in the 10th century, and was widely used from around the 12th century on. Cogs were generally built of oak, which was an abundant timber in the Baltic region of Prussia. This vessel was fitted with a single mast and a square-rigged single sail. These vessels were mostly associated with seagoing trade in medieval Europe, especially the Hanseatic League, particularly in the Baltic Sea region. They ranged from about 15 meters to 25 meters in length (49 ft to 82 ft) with a beam of 5 to 8 meters (16 ft to 26 ft), and the largest cog ships could carry up to about 200 tons.
Cogs were characterized by a flush-laid flat bottom at midships but gradually shifted to overlapped strakes near the posts. They had full lapstrake planking covering the sides, generally starting from the bilge strakes, and double-clenched iron nails for plank fastenings. The keel, or keelplank, was only slightly thicker than the adjacent garboards and had no rabbet. Both stem and stern posts were straight and rather long, and connected to the keelplank through intermediate pieces called hooks. The lower plank hoods terminated in rabbets in the hooks and posts, but upper hoods were nailed to the exterior faces of the posts. Caulking was generally tarred moss that was inserted into curved grooves, covered with wooden laths, and secured by metal staples called sintels. Finally, the cog-built structure could not be completed without a stern-mounted hanging central rudder, which was a unique northern development. Cogs used to have open hulls and could be rowed short distances. In the 13th century they received decks.
CHORUS:
I'm pushin' down the ave. no one lookin' good
I'm baggin' stones niggas diamonds up against that wood.
I'm pushin' down the ave. no one lookin' good
I'm baggin' stones niggas diamonds up against that wood.
I'm pimpin' down the ave. you know I'm lookin' tight
These jealous niggas looking at me and my car so shife.
Wanna take my life, and wanna jack, but I see all through that,
Never let these bitch niggas take what's mine nigga never do that
Who's says he's going through a thang when ya'll ain't never lied.
I gotta a baby but it's momma act like he ain't mine.
Wicked women using children to live on
When I hurt and try to hate cause she knows the thrill is gone
Say man I stop smokin' with haters back in 94
But niggas thinkin' that a sweeps gone get the through my door
And niggas talk alot of shit in a safe place,
I know cause he can't look me eye-to-eye when he in my face
Now nigga listen to my thesis, see just what I mean
Nigga I ride dirty everyday, but still I shine so clean
Glitter and gleam, and all what it look like
So I keep swangin' I hear clanging tryin' to live my life
CHORUS (2x)
I see these niggas and days go and come
And fo me just to wake, I'm know I'm pissed
I grab my cis and I split my sista with my bunk
Some of my sweets be tight And some of my sweets be fucked up
But all of my sweets gonna blow so killas smoke get sucked up
I looked up today and didn't fall prey to none of that pistol play
But who is to say tomorrow they won't be blastin' this-a-way
I'm puffin' spliffs of hay Still upset about the drama here
At this time of year I'm wipin' away my dead homey momma's tears... shit..
But naturally them fuckin' laws is always after me
So I have to be in that matter on that 5-0-3
I'm livin' dastardly
Must be all about survival G
These niggas passin' me streets keep on gettin' live with me.
They say there has to be another way but I ain't feelin that.
They try to steal a lad, and my wig they wanna peel it back.
But still the fact remains. It's all about the game swangin' bang
Peace to E-S-G and all the victims of the game
CHORUS (3x)
I'm pimpin' through the ave. tryin' to see some good
But everythang is still the same in my neighborhood
Niggas frown when you up and smile when you down
And when you change for the better shife fools stop comin' around
I see the jealousy and hate, the wicked ways
We all lost children, pray for papers, and smokin' our lives away
Got to the point where I could not decipher day from night
She say she love me but all we do now is fuckin' fight
My conscience fuck with me so much I can't eat or sleep
The other side is sellin' dope and out there runnin' the streets
And even though I'm gaining street fame comin' from this rap game
Lust for thankin' and compulsive drankin' is a normal thang
Some get erased and misplaced tryin' to win the race
Some try to hold on to there place by smokin' with lace
But see drugs and plastic thugs ain't gonna change the hood
I'm smokin' skunk and poppin' the truck to make me feel good.
CHORUS (2x)
So it's your life...
