To compare the engineering stress-strain curve with the true stress-strain curve.

To identify the type of material being tested.

To determine the modulus of elasticity of the material.

To calculate the true strain of a steel rod. (correct)

The engineering curve is used for compression, while the true curve is used for tension.

The engineering curve is for brittle materials, while the true curve is for ductile materials.

The engineering curve is based on the original dimensions of the material, while the true curve is based on the instantaneous dimensions. (correct)

The true curve is a measure of the material's strength, while the engineering curve is a measure of its toughness.
