What is tensile strain?

The ratio of change in length to the original length

The ratio of tensile force to the change in length

The ratio of original length to the change in length

The ratio of change in length to the tensile force applied

Correct Answer : The ratio of change in length to the original length

Explanation : The tensile stress is the ratio of tensile force to the change i length. It is the stress induced in a body when subjected to two equal and opposite pulls. The ratio of change in length to the original length is the tensile strain.
