Question
Physics Question on Stress Strain Curve
The stress-strain graphs for two materials A and B are shown in figure. (Assume same scale)
A
Material A is more brittle than material B
B
Material B is more brittle than material A
C
Materials A and B have the same brittleness
D
Information is insufficient
Answer
Material B is more brittle than material A
Explanation
Solution
If the ultimate tensile strength and fracture points are close, the material is said to be brittle. Hence, material B is more brittle than material A.
