span
spick and spanTotally clean and/or organized. I plan to spend the day cleaning so that this place is spick and span when my mother-in-law arrives.See also: and, spanspick and spanNeat and clean, as in When Ruth has finished cleaning, the whole house is spick and span. This term combines two nouns that are now obsolete, spick, "a nail" or "spike," and span, "a wooden chip." In the 1500s a sailing ship was considered spick and span when every spike and chip was brand-new. The transfer to the current sense took place in the mid-1800s. See also: and, spanspick and span mainly BRITISHIf a place is spick and span, it is very clean and tidy. Note: `Spick' is sometimes spelled `spic'. Ann was dusting the furniture, making sure her home was spick and span. The facilities were all spick and span. Note: You can also use spick-and-span before a noun. Its bright new buildings already resemble a spic-and-span Japanese car plant. Note: This expression has developed from an old-fashioned expression `spick and span-new', meaning `very new'. `Spick' probably came from a Dutch word meaning `new', and `span-new' meant `completely new'. See also: and, spanˌspick and ˈspan (also ˌspic and ˈspan) clean, tidy and fresh: The boss likes everything spick and span in the office.See also: and, spanspick and spanNeat and clean. This term is made up of two now obsolete words, spick, meaning a spike or nail, and span, meaning a wood chip. In the days of sailing ships, a spick and span ship was one in which every spike or nail and every (wooden) chip was new. The alliterative pairing of the two is very old indeed, although originally the expression meant “brand-new.” It appeared in Sir Thomas North’s translation of Plutarch’s Lives (1579): “They were all in goodly gilt armours, and brave purple cassocks upon them, spicke, and spanne newe.”See also: and, spanspic and spanNeat and clean. A “spick” was a nail (as in “spike”), “span” was a wood shaving, and a new wooden object had shiny spicks in it and fresh spans around it. Over the years the meaning of newness was replaced by that of something fresh and clean (as a new object usually was).See also: and, span, spicspan
span1. Psychol the amount of material that can be processed in a single mental act 2. short for wingspan3. a unit of length based on the width of an expanded hand, usually taken as nine inches SpanThe interval between any two consecutive supports of a beam, girder, or truss or between the opening of an arch.   Span of a bridge, the part of a bridge that extends between the bridge piers and carries various loads, such as transportation vehicles, pedestrians, and winds, which it transfers to the piers. A span consists of such bearing components as longitudinal beams or trusses, crossbeams or diaphragms, and slabs for the roadway. In arch bridges the main bearing components are the arches, which support the structure above them. Loads carried by spans are transferred to piers through bearing parts. The roadway slab of a span supports a roadbed and pedestrian sidewalks. The surface of the slab is paved with a layer of topping of asphalt or cement concrete and waterproofing. The material used for a span may be a metal, such as an aluminum alloy or steel, plain or reinforced concrete, native stone, or wood. The span is the most important part of a bridge. The structural design of a bridge and its static diagram depend on the static diagram of the span. The span may be of the girder, frame, arch, suspension, guy, or combination type. The general architectural composition of a bridge is essentially dependent on the type of span. Ordinarily a span is rectilinear as viewed from the top, although the spans of modern bridges, viaducts, and overpasses over the junctions of transportation lines may have more complicated shapes and be spiraled, ringed, or branched. The static diagram and the structural material used determine the way in which a span is constructed. Spans are usually built from prefabricated units manufactured in specialized plants or yards.
Span in buildings and structures, the distance between the neighboring supports of horizontal structural elements. There are spans, for example, between the columns that support a roof truss and between the piers that support a bridge span. Standardized span dimensions that conform to the Unified Modules System are currently used in construction in the USSR. span[span] (aerospace engineering) The dimension of a craft measured between lateral extremities; the measure of this dimension. Specifically, the dimension of an airfoil from tip to tip measured in a straight line. (engineering) A structural dimension measured between certain extremities. (mathematics) For a set A, the intersection of all sets that contain A and have some specified property. Also known as hull. For a set of vectors, the set of all possible linear combinations of those vectors. Also known as linear span. (statistics) The difference between the highest value and the lowest value in a range of values. bearing distance, spanThe length of a beam between its bearing supports.
span1. The interval between two terminals of a construction. 2. The distance apart of any two consecutive supports, esp. as applied to the opening of an arch. 3. A structural member (or part of a member) between two supports.span  i. The tip-to-tip distance of a wing. Winglets, tip tanks, and tip pods are not included while measuring the span.
ii. The operating radial distance from the root to the tip of a rotating airfoil, such as helicopter rotors or turbine or compressor blades.span
