Bucklandite, английский
Buckle, английский
- Also called "oil canning"; a distortion of a metal surface, appearing as a bulge or
- A mast buckles when it suffers by compression, so that the fibre takes a sinuous form, and the grain is upset. also, in polar regions, the bending or arching of the ice upwards, preceding a nip.
- The bend in a piece of drill-stem equipment induced by excessive feed pressure.
- The deformation of component members of a drill derrick, tripod, or mast, caused by attempting to hoist too heavy a load or by applying excessive strain when pulling on stuck casing, etc.
- (1) indentation on a flat face of a casting that may be caused by expansion of molding sand or by the dip coat of an investment casting peeling away from the pattern. (2) local waviness in rolled metal sheet or bar stock, usually transverse to the rolling direction. (3) failure mode of a compressed component that is characterized by unstable lateral deflection.

(2) local waviness in rolled metal sheet or bar stock, usually transverse to the rolling direction. (3) failure mode of a compressed component that is characterized by unstable lateral deflection. burnt-in sand: in manufacturing, discontinuity consisting of mixture of sand and metal cohering to surface of casting.
Buckle (track), английский
A substantial displacement of track from its original design alignment caused by longitudinal thermal stresses overcoming the lateral resistance of the track
Buckle guy, английский
Line attached to the middle of a spar tree or steel tower (32).
Buckler, английский
An ornament used in the decoration of friezes; sometimes circular or lozenge-shaped. buffer 145
Bucklers, английский
Two blocks of wood fitted together to stop the hawse-holes, leaving only sufficient space between them for the cable to pass, and thereby preventing the ship taking in much water in a heavy head-sea. they are either riding or blind bucklers (which see).
Buckley, английский
Buckling, английский
- The collapse of a slender vertical element which has been subjected to compression, leading to a sudden sideways deflection.
- Прогиб
- Выпучивание, образование бухтин
- Деформация buck-passing 1. передача маркера; 2. с передачей маркера
- Образование перегиба в кристаллах
- The breaking out of fragments along the surface of a column or tunnel
Buckling -, английский
Прочность при продольном изгибе; предел устойчивости при продольном изгибе
Buckling length, английский
The length of drill rod that will with¬stand flexure or bending when subjected to a specific feed pressure or compressional load.
Buckling length:, английский
- Length of an equivalent uniform member with pinned ends, which has the same cross-section and the same elastic critical force as the verified uniform member (individual or as a component of a frame structure).
- System length of an otherwise similar member with pinned ends, which has the same buckling resistance as a given member or segment of member
Buckling load, английский
- The load, 1 under which a structural member distorts under compression. buckling load, brit. crippling load the axial load at which a perfectly straight column or structural member starts to bend.
- The maximum load expressed in pounds or tons that can be imposed on a string of drill rods, casing, or pipe, or on a drill tripod, derrick, or mast without the string; also, a part being bent or buckled. compare collapsing strength.
Buckling mode, английский
Buckling strength, английский
Buckling stress, английский
Buckling:, английский
The ultimate limit state where the structure suddenly loses its stability under membrane compression and/or shear. it leads either to large displacements or to the structure being unable to carry the applied loads.
Resistance, английский
- Property of a conductor that opposed the current flow produced by a given difference of potential. the ohm is the practical unit of resistance.
- Уровень сопротивления - уровень цен, при котором активные продажи могут приостановить или развернуть тенденцию к повышению;
- Сопротивление (параметр)
- Сопротивление
- Сопротивление, т. е. уровень цен, при котором активные продажи могут приостановить или развернуть тенденцию к повышению.
- 1. the ability of a person not to get a disease 2. the ability of bacteria or a virus to remain unaffected by a drug the bacteria have developed a resistance to certain antibiotics. 3. opposition to a force
- Resistencia
- Устойчивость; резистентность resource for child health (reach)
- Устойчивость; резистентность
- The property of opposing movement, for example [1] electrical conductors offer resistance to the flow of electricity and dissipate some of its energy, usually as heat. [2] water resists the movement of vessels or other objects by parasitic drag, consuming some of the power available to drive the vessel forward.
- Imperviousness of the coating to mechanical, chemical, physical or weather influences
- Capacity of a member or component, or a cross-section of a member or component of a structure, to withstand actions without mechanical failure e.g. bending resistance, buckling resistance, tension resistance
- A material’s ability to restrict the flow of electrical current through itself. measured in ohms.
- The opposition of a circuit to the flow of current . resistance is measured in ohms, and can be calculated by dividing the voltage by current.
- The ability to impede (resist) the flow of electric current. with the exception of superconductors, all substances have a greater or lesser degree of resistance. substances with very low resistance, such as metals, conduct electricity well and are called conductors. substances with very high resistance, such as glass and rubber, conduct electricity poorly and are called nonconductors or insulators.
- An effective upper bound on prices achieved because of many willing sellers at that price level.
- Capacity of a component, or cross section of a component of a structure to
- The opposition to the flow of an electrical current through a conductor or circuit that does not include inductive or capacitive elements. it can be expressed as the ratio of the applied voltage to the current.
- Resistance is the opposition to the flow of an electrical current through a conductor. its unit is the ohm.
Resistance, французский
Resistance (r), английский
The property of a conductor, which opposes the flow of an electric current resulting in the generation of heat in the conducting material. the measure of the resistance of a given conductor is the electromotive force needed for a unit current flow. the unit of resistance is ohms.
Resistance (resistivity), английский

Сопротивление продольному изгибу, русский
Сопротивление материалов, русский
- , наука о прочности и деформируемости элементов сооружений и деталей машин. основные объекты изучения - стержни и пластины, исследуемые теоретическими и экспериментальными методами. главная задача сопротивления материалов - создание методов расчета элементов (деталей) на прочность, жесткость, устойчивость и колебания при действии статической и динамической нагрузок. эти методы используются в инженерной практике для определения наибольших напряжений и перемещений в элементах и сравнения их с нормативными величинами, безопасными для эксплуатации сооружения (машины).
