Home » Mechanics and Structural Analysis » Mechanical and structural analysis miscellaneous » Question

The stress-strain diagram for two materials A and B i s shown below:

The following statements are made based on this diagram:
(I) Material A is more brittle than material B.
(II) The ultimate strength of material B is m ore than that of A.
With reference to the above statements, which of the following applies?

1. Both the statements are false
2. Both the statements are true
3. I is true but II is false
4. I is false but II is true.

Correct Option: C

For material A failure occurs suddenly them material B,
∴ A is more brittle than B.
From the graph, it is clear material A is having more ultimate strength.
