Young's modulus is a measure of the stiffness of an elastic material, and it is defined as the ratio of stress to strain. Rocks with low Young's modulus tend to be ductile and rocks with high Young's modulus tend to be brittle.

Young's modulus is a measure of the stiffness or elasticity of a material. It quantifies the relationship between the longitudinal stress (or tension) and longitudinal strain of a material. When a material is subjected to an applied force along its length, it experiences deformation (strain) in the same direction as the force. Young's modulus helps us understand how much a material will stretch or compress under a given stress.
The correct answer to the question is option 'D': Young's modulus is defined as the ratio of longitudinal stress and longitudinal strain. Let's understand this in detail:
1. What is longitudinal stress and longitudinal strain?
- Longitudinal stress: When a force is applied to a material in the direction of its length, it creates stress within the material along that direction. This stress is called longitudinal stress.
- Longitudinal strain: The deformation or change in length of a material due to longitudinal stress is called longitudinal strain. It is a measure of how much a material elongates or contracts under a given stress.
2. Understanding Young's modulus:
- Young's modulus (E) is a material property that relates longitudinal stress (σ) and longitudinal strain (ε) through the equation: E = σ/ε.
- It represents the slope of the stress-strain curve in the linear elastic region, where the material behaves elastically and obeys Hooke's law.
- A higher Young's modulus indicates a stiffer material, meaning it requires a larger stress to produce a given strain.
3. Importance and applications:
- Young's modulus is a fundamental property used to characterize and compare the mechanical behavior of different materials, such as metals, polymers, and ceramics.
- It helps engineers and designers select appropriate materials for specific applications based on their desired stiffness or elasticity.
- Young's modulus is crucial in structural engineering, where it determines the deformation and stability of structures under various loads.
- It is also important in materials science research and development to understand the mechanical behavior and performance of materials.
In summary, Young's modulus is defined as the ratio of longitudinal stress and longitudinal strain. It quantifies the stiffness or elasticity of a material and is widely used to characterize and compare different materials.
