A rectаngulаr steel plаte [E = 195 GPa, ν = 0.29, and Y = 270 MPa] has a width оf 0.7 m, a length оf 1.4 m, and a thickness оf 30 mm. All four edges are simply supported. The plate is subjected to a uniform pressure of 120 kPa. Ignoring the effect of Poisson's ratio, determine the maximum bending moment per unit width in the plate.
