Hardness and Strength are they Same…?

No, hardness and strength are not the same, although they are related properties of materials.

Hardness refers to a material's resistance to indentation, scratching, or abrasion. It is a measure of how easily a material can be scratched or deformed by an external force. Hardness is typically determined by conducting specific tests, such as the Rockwell hardness test or the Vickers hardness test. Hardness is usually expressed using a scale, such as the Mohs scale for minerals or the Rockwell scale for metals.

Strength, on the other hand, refers to a material's ability to withstand an applied load or force without deformation or failure. It is a measure of how much stress a material can handle before it starts to deform or break. Strength is usually measured in terms of tensile strength, compressive strength, or shear strength, depending on the type of loading the material experiences.

While there can be some correlation between hardness and strength in certain materials, it is not a direct relationship. For example, a material can be very hard but relatively weak, meaning it can resist scratches but has low resistance to deformation or breaking. Conversely, a material can be softer but have high strength, indicating it can be easily scratched but has a high resistance to deformation or breaking.

In summary, hardness and strength are distinct properties that measure different aspects of a material's behavior under different conditions
