A cam is a rotating or sliding piece in a mechanical linkage used especially in transforming rotary motion into linear motion or vice-versa. It is often a part of a rotating wheel (e.g. an eccentric wheel) or shaft (e.g. a cylinder with an irregular shape) that strikes a lever at one or more points on its circular path. The cam can be a simple tooth, as is used to deliver pulses of power to a steam hammer, for example, or an eccentric disc or other shape that produces a smooth reciprocating (back and forth) motion in the follower, which is a lever making contact with the cam.
The cam can be seen as a device that translates from circular to reciprocating (or sometimes oscillating) motion. A common example is the camshaft of an automobile, which takes the rotary motion of the engine and translates it into the reciprocating motion necessary to operate the intake and exhaust valves of the cylinders.
Cams can also be viewed as information-storing and -transmitting devices. Examples are the cam-drums that direct the notes of a musical box or the movements of a screw machine's various tools and chucks. The information stored and transmitted by the cam is the answer to the question, "What actions should happen, and when?" (Even an automotive camshaft essentially answers that question, although the music box cam is a still-better example in illustrating this concept.)
Come on
You can feel her coming, coming at you
She, she's staying on you
You know she's coming at you
To resist her seems impossible
You can't do it, no you can't do it, no you can't do it
Hey lady what you say
How about some fun today?
Is it yes? Is it no?
Whatever it is just let me know
Don't fake me out, out
Oh, you make me shout
Alligator woman, you don't care
You ignore my desires, it ain't fair
You just want to tease me and turn me on
I wish you would leave but I don't want to be alone, no
Hey, babe I love you so
You know I don't want to go
Even though you're real laid back
You're dressed in black
And your hair is laid back
Hey lady what you say
How about some fun today?
Is it yes? Is it no?
Whatever it is just let me know
Don't fake me out, out
Oh, you make me shout
Alligator woman, you don't care
You ignore my desires, it ain't fair
You just want to tease me and turn me on
I want you to go but I don't want to be alone, ho
You're a mess, I must confess
You make me hot, with what you've got
Your big behind, it makes me blind
Don't take me gross but you're the most
You're a mess, I must confess
You make me hot, with what you've got
Your big behind, it makes me blind
I must be gross
Aw girl, aw girl
Aw girl, aw girl
Alligator woman, you don't care
You ignore my desires, it ain't fair
You just want to tease me and turn me on
I don't want you to stay but I don't want to be alone, now
You're a mess, I must confess
You make me hot, with what you've got
Your big behind, it makes me blind
Don't take me gross but you're the most
You're a mess, I must confess
You make me hot, with what you've got
Your big behind, it makes me blind
