For a given material, the Young's modulus is \(2.4\) times that of rigidity modulus. Its poisson's ratio is
- A \(2.4\)
- B \(1.2\)
- C \(0.4\)
- D \(0.2\)
Answer & Solution
Correct Answer
(D) \(0.2\)
Step-by-step Solution
Detailed explanation
\(Y=2 \eta(1+\sigma)\)
\(\Rightarrow \quad 2.4 \eta=2 \eta(1+\sigma)\)
\(\Rightarrow \quad 1.2=1+\sigma\)
\(\Rightarrow \quad \sigma=0.2\)
\(\Rightarrow \quad 2.4 \eta=2 \eta(1+\sigma)\)
\(\Rightarrow \quad 1.2=1+\sigma\)
\(\Rightarrow \quad \sigma=0.2\)
