Answer 2

Answer:

Modulus of elasticity or Young's Modulus (E), Shear Modulus (G), Bulk Modulus (K) and Poisson's Ratio (u) are the elastic constants.

Relationship between elastic constants.

E = 2G × (1+u)

E = 3K × (1-2u)

E = 9KG/(3K+G)

u = (3K-2G)/(6K+2G)

Here, in this question we should to use,

E = 3K × (1-2u)

E = 3 × 255 × (1-2×0.3)

E = 765 × 0.4

E = 306

Thus, modulus of elasticity, E = 306 GPA.
