strain   (strān)  Pronunciation Key 


(click for larger image in new window)

  1. A group of organisms of the same species, sharing certain hereditary characteristics not typical of the entire species but minor enough not to warrant classification as a separate breed or variety. Resistance to specific antibiotics is a feature of certain strains of bacteria.

  2. The extent to which a body is distorted when it is subjected to a deforming force, as when under stress. The distortion can involve a change both in shape and in size. All measures of strain are dimensionless (they have no unit of measure). ◇ Axial strain is equal to the ratio between the change in length of an object and its original length. ◇ Volume strain is equal to the ratio between the change in volume of an object and its original volume. It is also called bulk strain.Shear strain is equal to the ratio between the amount by which an object is skewed and its length. Compare stress. See more at Hooke's law.
