What is the meaning of strain in English literature?

What is the strain of something?
countable/uncountable pressure caused by a difficult situation. a strain on something: This war will put a great strain on the economy. the strain of something: I can’t take the strain of another move.
What is strain explain?
Strain is the amount of deformation experienced by the body in the direction of force applied, divided by the initial dimensions of the body. The strain is a dimensionless quantity as it just defines the relative change in shape.
What are the different types of strain?
Hint: There are three types of strain namely normal or longitudinal strain, shearing strain and volumetric or bulk strain which have been categorized on the basis of type of distortion produced by them.
What is strain unit?
The unit for strain in the SI (Système International) is “one” i.e. 1 ε= 1 = 1 m/m. In practice, the “unit” for strain is called “strain” and the symbol e is used. Usually, strain is in the order of um/m, i.e. 10-6, and therefore, the unit “µε” (microstrain) is most commonly used.
What is strain in human body?
A strain is when a muscle or tendon (tissue that attaches muscle to bone) is stretched too far. A strain is sometimes called a “pulled muscle.” Depending on the level of muscle strain, it may heal within a few weeks, but reinjury can happen.
What is the cause of strain?
What causes a strain? A strain is caused by twisting or pulling a muscle or tendon. Strains can be acute or chronic. An acute strain is caused by trauma or an injury such as a blow to the body; it can also be caused by improperly lifting heavy objects or over-stressing the muscles.
What is the physical meaning of strain?
Strain, in physical sciences and engineering, number that describes relative deformation or change in shape and size of elastic, plastic, and fluid materials under applied forces. In the case of elongation, or lengthwise compression, the normal strain is equal to the change in length divided by the original length.
What is true stress and true strain?
True stress is the applied load divided by the actual cross-sectional area (the changing area with respect to time) of the specimen at that load. Engineering strain is the amount that a material deforms per unit length in a tensile test.
What does the name strain mean?
Strain(noun) hereditary character, quality, or disposition. Strain(noun) rank; a sort. Strain(adj) to draw with force; to extend with great effort; to stretch; as, to strain a rope; to strain the shrouds of a ship; to strain the cords of a musical instrument.
What is the plural of strain?
The noun strain can be countable or uncountable. In more general, commonly used, contexts, the plural form will also be strain.
What does strain mean?
Strain(noun) the act of straining, or the state of being strained. Strain(noun) a violent effort; an excessive and hurtful exertion or tension, as of the muscles; as, he lifted the weight with a strain; the strain upon a ship’s rigging in a gale; also, the hurt or injury resulting; a sprain.
What is the dimension of strain?
Strain is the ratio of this change in length of the body to the original lenght. That is strain =change in length/original length. Hence both numerator and denominator have same dimension (lenghth), the strain is dimension less.
