A rectаngulаr steel plаte [E = 205 GPa, ν = 0.29, and Y = 260 MPa] has a width оf 0.8 m, a length оf 1.2 m, and a thickness оf 35 mm. The two longer edges are fixed, and the two shorter edges are simply supported. The plate is subjected to a uniform pressure of 60 kPa. Considering the effect of Poisson's ratio, determine the maximum bending stress in the plate.
