Disc brakeA disc brake is a type of brake that uses the calipers to squeeze pairs of pads against a disc or a "rotor" to create friction. This action slows the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary. The energy of motion is converted into waste heat which must be dispersed. Hydraulically actuated disc brakes are the most commonly used form of brake for motor vehicles, but the principles of a disc brake are applicable to almost any rotating shaft.
AdobeAdobe (əˈdoʊbi ; aˈðoβe) is a building material made from earth and organic materials. Adobe is Spanish for mudbrick. In some English-speaking regions of Spanish heritage, such as the Southwestern United States, the term is used to refer to any kind of earthen construction, or various architectural styles like Pueblo Revival or Territorial Revival. Most adobe buildings are similar in appearance to cob and rammed earth buildings. Adobe is among the earliest building materials, and is used throughout the world.
Brick and mortarBrick and mortar (or B&M) is an organization or business with a physical presence in a building or other structure. The term brick-and-mortar business is often used to refer to a company that possesses or leases retail shops, factory production facilities, or warehouses for its operations. More specifically, in the jargon of e-commerce businesses in the 2000s, brick-and-mortar businesses are companies that have a physical presence (e.g., a retail shop in a building) and offer face-to-face customer experiences.
BrickworkBrickwork is masonry produced by a bricklayer, using bricks and mortar. Typically, rows of bricks called courses are laid on top of one another to build up a structure such as a brick wall. Bricks may be differentiated from blocks by size. For example, in the UK a brick is defined as a unit having dimensions less than and a block is defined as a unit having one or more dimensions greater than the largest possible brick. Brick is a popular medium for constructing buildings, and examples of brickwork are found through history as far back as the Bronze Age.
Brick GothicBrick Gothic (Backsteingotik, Gotyk ceglany, Baksteengotiek) is a specific style of Gothic architecture common in Northeast and Central Europe especially in the regions in and around the Baltic Sea, which do not have resources of standing rock (though glacial boulders are sometimes available). The buildings are essentially built using bricks. Buildings classified as Brick Gothic (using a strict definition of the architectural style based on the geographic location) are found in Belgium (and the very north of France), Netherlands, Germany, Poland, Lithuania, Latvia, Estonia, Kaliningrad (former East Prussia), Denmark, Sweden and Finland.
Rational root theoremIn algebra, the rational root theorem (or rational root test, rational zero theorem, rational zero test or p/q theorem) states a constraint on rational solutions of a polynomial equation with integer coefficients and . Solutions of the equation are also called roots or zeros of the polynomial on the left side. The theorem states that each rational solution x = p⁄q, written in lowest terms so that p and q are relatively prime, satisfies: p is an integer factor of the constant term a0, and q is an integer factor of the leading coefficient an.
