The stress- strain graphs for materials ...

The stress- strain graphs for materials `A` and `B` are as shown. Choose the correct alternative

A

material `A` is stronger than material `B`

B

material `B` is stronger than material `A`

C

Young's modulus of `A` is greater than that of `B`

D

Young's modulus of `B` is greater than that of `A`

Text Solution

Verified by Experts

The correct Answer is:
B, C
Since the elastic limit of `B` is greater than that of `A`, `B` is stronger than `A`
Since for a given stress, strain in `A` is smaller than that of `B`. Since `Yxx(1)/(strain)`, Young's modulus of `A` is greater than that of `B`
