61. A material has a positive volumetric strain. What type of stress is most likely applied to the material?

1. Shear stress
2. Compressive stress
3. Tensile stress
4. No stress applied

Answer

The correct answer is: C) Tensile stress

Explanation

When a material is being tugged or stretched, tensile stress occurs in volume expansion, which is shown by a positive volumetric strain.
