breg [ muški rod ]

cam [ imenica {mehanika} ]
Generiši izgovor

ETYM Dan. kam comb, ridge; or cf. W., Gael., and Irish, cam bent. Related to Comb.
Part of a machine that converts circular motion to linear motion or vice versa. The edge cam in an automobile engine is in the form of a rounded projection on a shaft, the camshaft. When the camshaft turns, the cams press against linkages (plungers or followers) that open the valves in the cylinders.
A face cam is a disc with a groove in its face, in which the follower travels. A cylindrical cam carries angled parallel grooves, which impart a to-and-fro motion to the follower when it rotates.
Shaped rotating disk to convert circular into linear motion.

crest [ imenica ]

ETYM Old Fren. creste, French cręte, Latin crista.
The top line of a hill, mountain, or wave.
A showy growth of e.g. feathers or skin on the head of a bird or other animal.
(Heraldry) In medieval times, used to decorate a helmet.

hill [ imenica ]

(1862-194English physicist. In 19he shared with his son Lawrence Bragg the Nobel Prize for Physics for their research work on X-rays and crystals.
Crystallography had not previously been concerned with the internal arrangement of atoms but only with the shape and number of crystal surfaces. The Braggs' work gave a method of determining the positions of atoms in the lattices making up the crystals, and for accurate determination of X-ray wavelengths. This led to an understanding of the ways in which atoms combine with each other and revolutionized mineralogy and later molecular biology, in which X-ray diffraction was crucial to the elucidation of the structure of DNA.
Bragg was born in Westward, Cumberland. He obtained a first-class degree in mathematics from Cambridge 18and was immediately appointed professor of mathematics and physics at the University of Adelaide, South Australia. In 19he returned to the UK as professor at Leeds; from 19he was professor at University College, London.
Bragg became convinced that X-rays behave as an electromagnetic wave motion. He constructed the first X-ray spectrometer 191He and his son used it to determine the structures of various crystals on the basis that X-rays passing through the crystals are diffracted by the regular array of atoms within the crystal.
