Labratory measurements show that when a certain material has a grain diameter of 2.33x10-2 mm it's yield strength is 107 MPa. When the material's grain diameter decreases to 1.84x10-2 mm it's yield strength increases to 117 MPa.

When the average grain diameter is increased to 3.20x10-2 mm, what is the modulus of resilience (in J/m^3) if the modulus of elasticity is known to be 134 GPa?
