Shear stress
| Oil glossary |
- Frictional force overcome in sliding one "layer" of fluid along another, as in any fluid flow. the shear stress of a petroleum oil or other newtonian fluid at a given temperature varies directly with shear rate (velocity). the ratio between shear stress and shear rate is constant; this ratio is termed viscosity of a newtonian fluid, the greater the shear stress as a function of rate of shear. in a non-newtonian fluid
- Напряжение сдвига. обусловленная вязкостью сила, действующая в районе сдвига ветра (си. wind shear) (bmg).
- A unit of frictional force overcome in sliding one layer of fluid along another. this is typically measured in pounds per square foot, with pounds representing the frictional force, and square feet representing the area of contact between the sliding layers.

Касательное напряжение, русский
(1) составляющая напряжения, касательная к плоскости, на которую действуют силы. (2) напряжение, появляющееся, когда параллельные плоскости в металлических кристаллах скользят поперек друг друга.

Shear, английский
- Hydraulically operated scissorlike device for crosscutting the stem of a tree. one type of tree shear uses a cutting blade, which closes parallel to the anvil (22).
- A condition of stress or strain where parallel planes slide relative to each other.
- In an adhesively bonded joint, stress, strain, or failure
- Сдвиг
- An iron spear, of three or more points, for catching eels.
- Учёт воздействия сдвига; ~ for
- Сдвиг, разрыв. см. shear stress; wind shear —напряжение сдвига; сдвиг ветра (вектор сдвига).
- A discontinuity formed by shear movement, often occurring as a "seam"
- That type of force which causes or tends to cause two contiguous parts of the same body to slide relative to each other in a direction parallel to their plane of contact.
Shear (shore, shorn), английский
Shear angle, английский
Угол сдвига (при резании); угол скалывания
Shear bands, английский
Shear block, английский
Plywood that is face nailed to short (2 x 4's or 2 x 6's) wall studs (above a door or window, for example). this is done to prevent the wall from sliding and collapsing.
Shear bolt, английский
Срезной винт, применяемый для постановки клина при направленном бурении
Shear break, английский
Open break in metal at the periphery of a bolt, nut, rod or member at approximately a 45 degree angle to the applied stress. shear breaks occur most often with flanged products. also called shear crack.2,5

An interconnection between the concrete and steel components of a composite member that has sufficient strength and stiffness to
Shear connector, английский
Usually metal connectors fitted inside a timber joint to transfer shear across a wide area of grain.

Temperature, английский
- Température
- Dry-bulb - temperature of air as indicated by a standard thermometer.
- An expression of thermal energy density. how hot or cold an object is.
- The measure of the intensity of heat that a substance possesses.
- Температура
- Температура тмр test methods and procedures методы проведения испытаний и последовательность их проведения тмр theodolite measuring point кинотеодолитная станция
- Temperatura, fiebre
- The condition attained when the wetted wick of a wet-bulb thermometer has reached a stable and constant temperature when exposed to moving air in excess of 900 ft (274.3 m) per minute.
- 1. the heat of the body or of the surrounding air, measured in degrees the doctor asked the nurse what the patient’s temperature was. his temperature was slightly above normal. the thermometer showed a temperature of 99°f. to take a patient’s temperature to insert a thermometer in someone’s body to see what his or her body temperature is they took his temperature every four hours. when her temperature was taken this morning, it was normal. 2. illness when your body is hotter than normal he’s in bed with a temperature. her mother says she’s got a temperature, and can’t come to work. comment: the average body temperature is about 37° celsius or 98° fahrenheit. this temperature may vary during the day, and can rise if a person has taken a hot bath or had a hot drink. if the environmental temperature is high, the body has to sweat to reduce the heat gained from the air around it. if the outside temperature is low, the body shivers, because rapid movement of the muscles generates heat. a fever will cause the body temperature to rise sharply, to 40°c (103°f) or more. hypothermia exists when the body temperature falls below about 35°c (95°f).
- Повышение температуры бетона ~ of truss высота фермы jet ~ высота подъёма горизонтальной неизотермической приточной струи, «всплывающей» над приточным отверстием
- Температура ~ of adiabatic saturation температура адиабатического насыщения
- Normal adult temperature varies among horses, but will usually range in degrees from 99.5°f to 100.5°f.
- A measure of the average kinetic energy of a material. the standard unit of temperature is a kelvin, (k). temperature determines the direction of heat flow between any two systems in thermal contact. heat will always flow from the area of higher temperature (t source) to one of lower temperature (t sink). temperature gradient (?t)
- A measure of the degree of molecular motion of a material compared to a reference point. temperature is measured in degrees farenheit (melting point of ice = 32 º f, boiling point of water = 212 º f) or degrees celsius (melting point of ice = 0 º c, boiling point of water = 100 º c).
- The degree of sensible heat of a body as measured by a thermometer or similar instrument.
- Measure of the intensity of particle motion in degrees celsius (°c) or degrees fahrenheit (°f) or, in the absolute scale, kelvin (k), where the increment of 1 k = 1 °c = 1.8 °f.
- Temperature of surrounding atmosphere. also called dry bulb temperature. compare standard atmospheric conditions. ampere (a): si unit of electric current. ampere per meter (a·m–1): si derived unit of magnetic field intensity. the measurement 1 a·m–1, for example, describes a current of 1 a flowing through a coil that is 1 m in diameter. compare oersted. ampere turn (at): in magnetic particle testing, unit for expressing the magnetomotive force required for magnetization using a coil in terms of the product of the number of coil turns and the current in amperes flowing through the coil. amplitude, echo: in ultrasonic testing, the vertical height of a received signal on an a-scan, measured from base to peak for a video presentation or from peak to peak for a radio frequency presentation.
- Measure of the intensity of particle motion in degrees celsius (°c), degrees fahrenheit (°f) or, in the absolute scale, kelvin (k) or degrees rankine (°r). an increment of 1 k = 1 °c = 1.8 °r = 1.8 °f. compare heat.
