List of moments of inertia. Moment of inertia, denoted by I, measures the extent to which an object resists rotational acceleration about a particular axis, it is the rotational analogue to mass (which determines an object's resistance to linear acceleration ). The moments of inertia of a mass have units of dimension ML 2 ( [mass] × [length] 2 ).
Heptagonal bipyramid. Properties. Convex semiregular. Vertex figure. 3D model of a (uniform) heptagonal prism. In geometry, the heptagonal prism is a prism with heptagonal base. This polyhedron has 9 faces (2 bases and 7 sides), 21 edges, and 14 vertices. [1] [2]
The Weld-Blundell Prism ("WB", dated 1800 BCE) is a clay, cuneiform inscribed vertical prism housed in the Ashmolean Museum in Oxford. [2] The prism was found in a 1922 expedition in Larsa in modern-day Iraq by British archaeologist Herbert Weld Blundell. [3] The four sides, about 20 cm high and 9 cm wide, are inscribed in the Sumerian language ...
A total station or total station theodolite is an electronic/optical instrument used for surveying and building construction. It is an electronic transit theodolite integrated with electronic distance measurement (EDM) to measure both vertical and horizontal angles and the slope distance from the instrument to a particular point, and an on-board computer to collect data and perform ...
The vertical bar, |, is a glyph with various uses in mathematics, computing, and typography. It has many names, often related to particular meanings: Sheffer stroke (in logic ), pipe, bar, or (literally the word "or"), vbar, and others.
A prism transom bends light passing through the upper part of the window upwards. Prism lighting is the use of prisms to improve the distribution of light in a space. It is usually used to distribute daylight, and is a form of anidolic lighting . Prism lighting was popular from its introduction in the 1890s through to the 1930s, when cheap ...
Cuboid. In geometry, a cuboid is a quadrilateral -faced convex hexahedron (a polyhedron with six faces). "Cuboid" means "like a cube ", in the sense of a convex solid which can be transformed into a cube by adjusting the lengths of its edges or/and the angles between its adjacent faces. In general mathematical language, a cuboid is a convex ...
Look up trapezoid in Wiktionary, the free dictionary. In geometry, a trapezoid ( / ˈtræpəzɔɪd /) in North American English, or trapezium ( / trəˈpiːziəm /) in British English, [1] [2] is a quadrilateral that has at least one pair of parallel sides. The parallel sides are called the bases of the trapezoid. The other two sides are called ...
