In construction, cylindrical or tapering piece of metal or plastic (or formerly wood) with a helical groove cut into it. Each turn of a screw moves it forward or backward by a distance equal to the pitch (the spacing between neighboring threads).
Its mechanical advantage equals 2 r/P, where P is the pitch and r is the radius of the thread. Thus the mechanical advantage of a tapering wood screw, for example, increases as it is rotated into the wood.
The thread is comparable to an inclined plane (wedge) wrapped around a cylinder or cone. + prikaži više

ETYM Old Eng. toth,tooth, as. tôth.
(Irregular plural: teeth).
1. Hard bonelike structures in the jaws of vertebrates; used for biting and chewing or for attack and defense.
2. Toothlike structure in invertebrates found in the mouth or alimentary canal or on a shell.
3. Something resembling the tooth of an animal.
In vertebrates, one of a set of hard, bonelike structures in the mouth, used for biting and chewing food, and in defense and aggression. In humans, the first set (20 milk teeth) appear from age six months to two and a half years. The permanent dentition replaces these from the sixth year onward, the wisdom teeth (third molars) sometimes not appearing until the age of 25 or 30. Adults have 32 teeth: two incisors, one canine (eye tooth), two premolars, and three molars on each side of each jaw. Each tooth consists of an enamel coat (hardened calcium deposits), dentine (a thick, bonelike layer), and an inner pulp cavity, housing nerves and blood vessels. Mammalian teeth have roots surrounded by cementum, which fuses them into their sockets in the jawbones.
The neck of the tooth is covered by the gum, while the enamel-covered crown protrudes above the gum line.
The chief diseases of teeth are misplacements resulting from defect or disturbance of the tooth-germs before birth, eruption out of their proper places, and caries (decay).
A genetically engineered protein able to stimulate the recovery of tooth tissue in decayed teeth was undergoing trials 1993. + prikaži više
