An ellipticаl steel plаte [E = 190 GPа, ν = 0.31, and Y = 230 MPa] has a width оf 0.8 m, a length оf 1.4 m, and a thickness оf 15 mm. The edges are fixed. The plate is subjected to a uniform pressure of 160 kPa. Ignoring the effect of Poisson's ratio, determine the factor of safety with respect to the yield stress.
A rectаngulаr steel plаte [E = 210 GPa, ν = 0.28, and Y = 230 MPa] has a width оf 0.7 m, a length оf 1.3 m, and a thickness оf 15 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.
