A rectаngulаr steel plаte [E = 190 GPa, ν = 0.30, and Y = 230 MPa] has a width оf 0.9 m, a length оf 1.3 m, and a thickness оf 30 mm. All four edges are simply supported. The plate is subjected to a uniform pressure of 170 kPa. Considering the effect of Poisson's ratio, determine the maximum bending stress in the plate.
