The correct Answer is:
To solve the question, we need to analyze the terms provided in the options and understand their definitions in the context of elasticity. ### Step-by-Step Solution: 1. **Understanding the Question**: The question asks for the term that describes the internal restoring force acting per unit area of the cross-section of a deformed body. 2. **Defining the Terms**: - **Strain**: This is a measure of deformation representing the displacement between particles in a material body. It is a dimensionless quantity and does not refer to force. - **Stress**: This is defined as the internal restoring force per unit area of the cross-section of a material. It quantifies how much force is exerted within a material when it is deformed. - **Elastic Limit**: This is the maximum extent to which a solid may be stretched without permanent alteration of size or shape. It does not refer to a force. - **Volumetric Strength**: This term is not commonly used in the context of internal forces and typically refers to the strength of a material in terms of its volume. 3. **Identifying the Correct Answer**: Among the options, "stress" is the only term that directly relates to the internal restoring force acting per unit area of the cross-section of a deformed body. 4. **Conclusion**: Therefore, the correct answer to the question is **stress**. ### Final Answer: The internal restoring force acting per unit area of cross-section of the deformed body is called **stress**. ---
