For any material, the modulus of elasticity at a point can be given by Ex, Ey, Ez. Which of the following properties is true for a homogeneous material ?
1
Ex = Ey = Ez, at a point and Ex ≠ Ey,≠ Ez at the other points throughout the material
2
Ex = Ey ≠ Ez at a point and Ex = Ey = Ez at the other points throughout the material
3
Ex ≠ Ey ≠ Ez, at a point and Ex = Ey = Ez at the other points throughout the material
4
Ex ≠ Ey ≠ Ez at a point and the same property exists at all the points throughout the material
