5. A rectangular block has dimensions of 3 in, 4 in, and 5 in along the x-, y-, and z- axes, respectively. The block is subjected to triaxial loading of three uniformly distributed loadings of 30 kips (C), 45 kips (T), and 60 kips (C) along the x-, y-, and z- axes, respectively. If the strain along the x- axis and the z-axis are 0.00021 (C) and 0.00042 (C), respectively, determine the Poisson's ratio and the modulus of elasticity of the material. Also, what is the change in volume of the material
