Question

Strength of a material is its ability to resist:

• A. Deformation due to stress
• B. Fracture due to high load
• C. External forces applied with yielding or break down
• D. The flow

Hint:

Material strength is an essential property in engineering. It defines the maximum stress that a material can withstand before undergoing significant deformation or fracture.

Answer 1

The Correct Option is C

The strength of a material refers to its ability to withstand external forces without undergoing permanent deformation, yielding, or fracture. This property is crucial for materials used in structural applications where high loads and forces are applied.
- Deformation due to stress is incorrect because deformation refers to any change in shape due to stress, but it doesn't necessarily mean the material has withstood the stress without failure.
- Fracture due to high load is incorrect because strength refers to the ability to resist fracture, not to cause it.
- The flow is incorrect because it doesn't relate directly to strength in a material context.
Therefore, the correct answer is (3), External forces applied with yielding or break down.
