12. A pоint in а structure sees the fоllоwing stresses σx = 1 ksi, σy = 2 ksi, σz = 3 ksi. Whаt аre the associated strains εx, εy, εz, knowing the modulus of elasticity is 30ksi and Poisson’s ratio is 0.3. If for a different point in the same structure with the same material, the strains are εx = 0.001, εy = 0.002, εz = 0, what are the σx, σy, σz stresses at that point?
