Calculation of Modulus of Elasticity

Modulus of elasticity can be calculated using the following formula:

Modulus of Elasticity (E) = 2 × Modulus of Rigidity (G) × (1 + Poisson's Ratio (ν))

Given, Modulus of Rigidity (G) = 100 GPa and Poisson's Ratio (ν) = 0.25

Substituting the values in the formula, we get:

Modulus of Elasticity (E) = 2 × 100 GPa × (1 + 0.25)

= 2 × 100 GPa × 1.25

= 250 GPa

Therefore, the value of modulus of elasticity in GPa is 250 (option D).
