Question

What is strain?

A) The ratio of the applied force to the cross-sectional area of an object
B) The maximum breaking strength of the material from which the object is made when stretched
C) The ratio of the change in an object's length to its original length when stretched or compressed.
D) The elastic property of the material from which the object is made related to stretching or compression.

Answer 1

C) The ratio of the change in an object's length to its original length when stretched or compressed.

Step-by-step explanation:

The formula for strain is:

Strain = Change in Length/Origin Length

Hence, it can be described as the percentile of change in the dimension with respect to the original dimension. So, whenever a tensile or a compressive force is applied on a body, its length changes. The ratio of this change to original length is called strain. So, the correct option is:

C) The ratio of the change in an object's length to its original length when stretched or compressed.
