Choose the correct relationship between Poisson ratio $(σ)$ , bulk modulus (K) and modulus of rigidity $(η)$ of a given solid object :

Accepted Answer

Poisson ratio ( $σ$ ), bulk modulus (K) and modulus of rigidity ( $η$ ) are related by

$∵ 2 η (1 + σ) = 3 K (1 - 2 σ)$

$2 η + 2 η σ = 3 K - 6 K σ$

$σ = \frac{3 K - 2 η}{2 η + 6 K}$
