An ellipticаl steel plаte [E = 190 GPа, ν = 0.28, and Y = 250 MPa] has a width оf 0.6 m, a length оf 1.2 m, and a thickness оf 25 mm. The edges are fixed. The plate is subjected to a uniform pressure of 130 kPa. Ignoring the effect of Poisson's ratio, determine the factor of safety with respect to the yield stress.
