Question

for a given material, the young's modulus is 2.4 times that of the modulus of rigidity. its poison's ratio is

Answer 1

Young's Modulus = 2 x Rigidity Modulus x ( 1 + Poisson's Ratio ) 
given, Young's Modulus = 2.4 x Rigidity Modulus
2.4 = 2 x ( 1 + Poisson's Ratio ) 
1.2 = 1 + Poisson's Ratio
Poisson's Ratio = 0.2

Answer 2
