Question

which of the following relation is not correct Y = Young's modulus, K= Bulk modulus, n= rigidity modulus , poisson's ratio​
1) 1/Y = 9n K/(3K+n)
2) Y/n = 2(1+Poissons ratio)
3) Y/3 K= 1(-2 Poissons ratio)
4) (Y/n)+(Y/3K)=3

Answer 1

Answer:

Young's modulus of elasticity of a material is the ratio of longitudinal stress to the longitudinal strain produced in a body made of same material. Bulk modulus of elasticity is the ratio of hydrostatic stress to volumetric strain.
