Stress strain curve of three types of material is given in the figure below. Please identify the correct combination.
- A. E- brittle, F - ductile, G - plastic
- B. E- plastic, F - brittle, G - ductile
- C. E- brittle, F - plastic, G - ductile
- D. E- ductile, F - plastic, G - brittle
Answer: A. E- brittle, F - ductile, G - plastic
Explanation: Curve E is steep and fractures without much plastic deformation, which is characteristic of a brittle material. Curve F shows significant strain before fracture, characteristic of a ductile material. Curve G is completely flat (horizontal), indicating continuous deformation at a constant stress, which is perfectly plastic.
