Ncube-2, a Norwegian CubeSat (10 cm (3.9 in) cube). A CubeSat is a class of small satellite with a form factor of 10 cm (3.9 in) cubes. [1] CubeSats have a mass of no more than 2 kg (4.4 lb) per unit, [2] and often use commercial off-the-shelf (COTS) components for their electronics and structure.
The royal gur-cube (Cuneiform: LU 2.GAL.GUR, 𒈚 ð’„¥; Akkadian: šarru kurru) was a theoretical cuboid of water approximately 6 m × 6 m × 0.5 m from which all other units could be derived. The Neo-Sumerians continued use of the royal gur-cube as indicated by the Letter of Nanse issued in 2000 BCE by Gudea.
Visualisation of a diamond cubic unit cell: 1. Components of a unit cell, 2. One unit cell, 3. A lattice of 3 × 3 × 3 unit cells. Diamond's cubic structure is in the Fd 3 m space group (space group 227), which follows the face-centered cubic Bravais lattice.
If the normal unit vector n of the surface (pointing from Q towards P) is assumed fixed, the normal component can be expressed by a single number, the dot product T · n. This number will be positive if P is "pulling" on Q (tensile stress), and negative if P is "pushing" against Q (compressive stress) The shear component is then the vector T ...
The cube can be dissected into six 3-orthoschemes, three left-handed and three right-handed (one of each at each cube face), and cubes can fill space, so the characteristic 3-orthoscheme of the cube is a space-filling tetrahedron in this sense.
The unit, named after Blaise Pascal, is an SI coherent derived unit defined as one newton per square metre (N/m 2). [1] It is also equivalent to 10 barye (10 Ba) in the CGS system. Common multiple units of the pascal are the hectopascal (1 hPa = 100 Pa), which is equal to one millibar , and the kilopascal (1 kPa = 1000 Pa), which is equal to ...
Nintendo predicted 50 million GameCube units by 2005, [231] but only sold 22 million GameCube units worldwide during its lifespan, [8] [232] placing it slightly behind the Xbox's 24 million, [233] though it did manage to outsell the Xbox in Japan, [234] and well behind the PlayStation 2's 155 million. [235] Its sales exceeded that of the Xbox ...
The kilogram per cubic metre (symbol: kg·m −3, or kg/m 3) is the unit of density in the International System of Units (SI). It is defined by dividing the SI unit of mass, the kilogram, by the SI unit of volume, the cubic metre. [1]
