An ellipticаl steel plаte [E = 200 GPа, ν = 0.31, and Y = 270 MPa] has a width оf 0.7 m, a length оf 1.1 m, and a thickness оf 25 mm. The edges are fixed. The plate is subjected to a uniform pressure of 200 kPa. Ignoring the effect of Poisson's ratio, determine the factor of safety with respect to the yield stress.
