the ration of change in length to it is original length is called....... strain
Answers
Explanation:
The tensile stress is the ratio of tensile force to the change i length. ... The ratio of change in length to the original length is the tensile strain.
Strain is a force that pulls or stretches something to an excessive or harmful extent. When an item is subjected to an external force per unit area (stress), it develops a deformation in its shape. The body's interatomic particles struggle to return to their original place. When the body's elastic limit is exceeded. The strain is a situation in which the internal restorative force fails to restore the body to its former shape. The elastic strain has the feature of being irreversible.
The term "longitudinal strain" is used to describe the strain that occurs throughout time. Return of an object's length to its initial length. It is symbolised by the Greek character epsilon and is caused by longitudinal tension.
∴ The ratio of change in length to it is original length is called longitudinal strain.
