The correct Answer is:
To solve the problem, we need to evaluate the two statements regarding the modulus of elasticity. ### Step 1: Analyze Statement 1 **Statement 1:** The value of modulus of elasticity depends on the magnitude of the stress and strain. - The modulus of elasticity is defined as the ratio of stress to strain within the elastic limit of a material. However, it is a material property and remains constant for a given material under normal conditions. - It does not change with the magnitude of stress and strain applied to the material. Therefore, this statement is **false**. ### Step 2: Analyze Statement 2 **Statement 2:** A given material has different moduli of elasticity depending on the type of stress applied. - This statement is true. Different types of stress result in different moduli of elasticity: - **Young's Modulus** is used for tensile or compressive stress. - **Shear Modulus** is used for shear stress. - **Bulk Modulus** is used for volumetric stress. - Hence, the modulus of elasticity does depend on the type of stress applied, making this statement **true**. ### Step 3: Conclusion Based on the analysis: - **Statement 1 is False.** - **Statement 2 is True.** Thus, the correct option is that Statement 1 is False and Statement 2 is True. ### Final Answer: - Statement 1: False - Statement 2: True
