  2. Six-dimensional space - Wikipedia

    en.wikipedia.org/wiki/Six-dimensional_space

    The 6-sphere, or hypersphere in seven dimensions, is the six-dimensional surface equidistant from a point. It has symbol S6, and the equation for the 6-sphere, radius r, centre the origin is. The volume of the space bounded by this 6-sphere is. which is 4.72477 × r7, or 0.0369 of the smallest 7-cube that contains the 6-sphere.

  3. Dimension - Wikipedia

    en.wikipedia.org/wiki/Dimension

    In mathematics. In mathematics, the dimension of an object is, roughly speaking, the number of degrees of freedom of a point that moves on this object. In other words, the dimension is the number of independent parameters or coordinates that are needed for defining the position of a point that is constrained to be on the object.

    They ordered a new special 2-6-2T from (Werkspoor, N.V., Amsterdam), Netherlands with specifications has a maximum axle weight of 10 tons with an effective tractive force of 5000 kg, could pass on the 3 ft 6 in (1,067 mm) gauge Riggenbach rack line between Jambu–Bedono–Gemawang which has 6.5% incline with 8 carriages or wagons at a speed of ...

  5. Two-dimensional space - Wikipedia

    en.wikipedia.org/wiki/Two-dimensional_space

    Two-dimensional space. A two-dimensional space is a mathematical space with two dimensions, meaning points have two degrees of freedom: their locations can be locally described with two coordinates or they can move in two independent directions. Common two-dimensional spaces are often called planes, or, more generally, surfaces .

  6. 2-6-6-6 - Wikipedia

    en.wikipedia.org/wiki/2-6-6-6

    The 2-6-6-6 (in Whyte notation) is an articulated locomotive type with two leading wheels, two sets of six driving wheels and six trailing wheels. Only two classes of the 2-6-6-6 type were built. One was the "Allegheny" class, built by the Lima Locomotive Works. The name comes from the locomotive's first service with the Chesapeake and Ohio ...

    en.wikipedia.org/wiki/Slowly_changing_dimension

    Slowly changing dimension. A slowly changing dimension ( SCD) in data management and data warehousing is a dimension which contains relatively static data which can change slowly but unpredictably, rather than according to a regular schedule. [1] Some examples of typical slowly changing dimensions are entities such as names of geographical ...

    The L52 (also called Vortec 3500 ), is a straight-5 DOHC engine produced from 2004 through 2006. It displaces 3.5 L; 211.1 cu in (3,460 cc), with a 93 mm × 102 mm (3.66 in × 4.02 in) bore and stroke. Dynoed at the flywheel it produces 220 hp (164 kW) at 5,600 rpm and 225 lb⋅ft (305 N⋅m) at 2,800 rpm. The engine redline is 6,300 rpm.

  9. Dimension (vector space) - Wikipedia

    en.wikipedia.org/wiki/Dimension_(vector_space)

    Dimension (vector space) A diagram of dimensions 1, 2, 3, and 4. In mathematics, the dimension of a vector space V is the cardinality (i.e., the number of vectors) of a basis of V over its base field. [1] [2] It is sometimes called Hamel dimension (after Georg Hamel) or algebraic dimension to distinguish it from other types of dimension .
