Question

calculate poisson's ratio o for brass.
Given : Y= 8x100 N/m²&k=8x100 N/m²
​

Answer 1

For silver, Young's modulus is 7.25×10

10

Nm

−2

and Bulk modulus is 11×10

10

Nm

−2

. The Poisson's ratio will be:

A

−1

B

0.5

C

0.39

D

0.25

MEDIUM

Answer

We have the relation as

Y=3K(1−2σ)

Substituting we get

7.25×10

11

=3×11×10

10

(1−2σ)

or

σ=0.39
