Questions
If the Young's modulus of the material is 3 times its modulus of rigidity, then its volume elasticity will be
a
zero
b
infinity
c
2 × 1010 N/m2
d
3 × 1010 N/m2
detailed solution
Correct option is B
Y=2η(1+σ)⇒3η=2η(1+σ)⇒σ=32−1=12Now, substituting the value of 0- in the following expressionY=3K(1−2σ)⇒ K=Y3(1−2σ)=∞Talk to our academic expert!
