Select the definition that best describes the term “strain.” A measure of the degree of plastic deformation that a material can withstand before failure.

The elongation (or change in length) of a specimen divided by the original length, sometimes referred to as percent elongation.

Indication of how much energy a material can absorb before failure.

Also known as the modulus of elasticity, this is the constant of proportionality as defined by Hooke’s Law.

The instantaneous force applied to a specimen divided by the cross-sectional area.

The elongation (or change in length) of a specimen divided by the original length, sometimes referred to as percent elongation.

Explanation:

Strain is defined mathematically as follows .

strain = Δ L/ L

Δ L is change in length of a wire when some force is applied on it to stretch it along its length and L is original length of a wire .

Stress is The elongation (or change in length) of a specimen divided by the original length, sometimes referred to as percent elongation.

The elongation (or change in length) of a specimen divided by the original length, sometimes referred to as percent elongation.

Explanation:

Every object has some elastic and inelastic properties.

The strain is defined as the ratio of change in dimensions to the original dimensions.

There are three types of strains:

1. Longitudinal strain

2. Volumetric strain

3. Shear strain

So, it is defined as elongation (or change in length) of a specimen divided by the original length, sometimes referred to as percent elongation.
