The principal stem or horn of a stag or other deer, which bears the antlers, or branches
A beam is a long thick bar of wood, metal, or concrete, especially one used to support the roof of a building. The ceilings are supported by oak beams. see also off-beam. In building construction, a horizontal member spanning an opening and carrying a load. The load may be a wall above the opening (see post-and-beam system) or it may be a floor or roof. Beams may be of wood, steel or other metals, reinforced or prestressed concrete, plastic, or even brick with steel reinforcement. For weight reduction, metal beams are I-shaped, having a thin vertical web and thicker horizontal flanges where greater stress occurs. A joist is any of a series of small parallel beams supporting a floor or roof. See also girder, spandrel
A unidirectional flow of radio waves concentrated in a particular direction A term commonly used to refer to an antenna's radiation pattern by analogy with a light beam It is most often used to describe the radiation pattern of satellite antennas The intersection of a satellite beam with the earth's surface is referred to as the (beam's) footprint
1 In radio interferometry, the inverse Fourier transform of the u-v sampling distribution, or of a weighted u-v sampling distribution, possibly convolved with a gridding convolution function: the idealized response to a point, or unresolved, radio source 2 A numerical approximation to 1 3 A digitized version of 2, sampled on a regular grid (usually regarded as an image) 4 Synonymous with point spread function 5 (Occasionally) as above, but taking into account instrumental effects, so that the beam depends on position in the sky See dirty image Occasionally, any one of the above, other than 5, is termed the synthesized beam
One of the principal horizontal timbers of a building; one of the transverse members of a ships frame on which the decks are laid - supported at the sides by knees in wooden ships and by stringers in steel ones
The main part of a plow, to which the handles and colter are secured, and to the end of which are attached the oxen or horses that draw it
