  3. A bar of elastic material is subjected to a direct compressive stress σ1 in the longitudinal direction. Suitable lateral compressive stress σ2 is applied along each of the other two lateral directions to limit the net strain in each of the lateral directions to half the magnitude of what it could be under σ1 acting alone. If μ is the Poisson's ratio of the material, then the magnitude of σ2 is
