Question

IF the yong modulus of the meterial is 3time its modulus of rigidity then its volume elasicity will be

Answer 1

Answer:

Correct option: (B) infinity

Explanation:

Y = 3K(1 – 2σ) (1)

Y = 2η(1 + σ) (2)

Given Y = 3η

from (2)

3η = 2η (1 + σ) i.e. σ = (3/2) –1 = (1/2)

from eqn (1),

K = [Y / {3(1 – 2σ)}] = [Y / {3(1 – 2 × {1/2})}] = ∞

Hence volume elasticity = ∞
