Math Problem Statement
On a cube element, a vertical compressive stress of 20 ksi is applied. The resulting lateral compressive stress is 12 ksi in both orthogonal lateral directions. The modulus of the material is 23,000 ksi and the Poisson’s ratio is 0.25. Calculate the vertical compressive strain of the cube element.
