A cubical element of a structural part made of mild steel is subjected to a tri-axial compressive stress as shown in the figure. The vertical compressive stress is σ1. The Modulus of Elasticity and Poisson's Ratio are E and μ, respectively. What should be the uniform lateral pressure σ2 in terms of σ1 and μ, so that lateral strain is prevented?
