Nominal stress is quoted with respect to the strength of a material and is qualified by the type of stress, such as tensile strength, compressive, or shear strength.

• A. Elastic Modulus
• B. Tensile, Compressive, or Shear strength
• C. Poisson's ratio
• D. Hardness

Answer: (B)

In materials terms, the value used to represent how strong a material is depends on how you load it. Nominal stress is tied to the strength figure you’re referencing, and you need to specify the loading mode to know what that strength means. The best fit here is tensile, compressive, or shear strength because those describe the failure stress under the different types of loading. Elastic Modulus tells you how stiff a material is (how much it deforms under load), not how much stress it can withstand before failing. Poisson's ratio describes how dimensions change laterally when stretched or compressed, not the strength itself. Hardness measures resistance to indentation, which is a different property from the strength under tension, compression, or shear. So, the nominal stress is quoted with respect to the strength corresponding to the loading type—tensile strength for pulling apart, compressive strength for crushing, or shear strength for sliding between planes.
