A rectangular steel block is 3.0 inches long in the x-direction, 3.0 inches long in the y-direction, and 4.5 inches long in the z-direction. The block is subjected to a tri-axial loading of three uniformly distributed forces as follows: 50 kips tension in the x-direction, 60 kips compression in the y-direction, and 54 kips tension in the z-direction. If Poisson's ratio is 0.30 and E = 29 x 106 psi, find the uniformly distributed load that must be added in the x-direction to produced no deformation in the z-direction. Your final answer should include two decimal places
