An ellipticаl steel plаte [E = 195 GPа, ν = 0.31, and Y = 270 MPa] has a width оf 0.6 m, a length оf 1.4 m, and a thickness оf 25 mm. The edges are fixed. The plate is subjected to a uniform pressure of 120 kPa. Ignoring the effect of Poisson's ratio, determine the factor of safety with respect to the yield stress.
A rectаngulаr steel plаte [E = 190 GPa, ν = 0.29, and Y = 240 MPa] has a width оf 0.7 m, a length оf 1.2 m, and a thickness оf 25 mm. The two shorter edges are fixed, and the two longer edges are simply supported. The plate is subjected to a uniform pressure of 110 kPa. Determine the maximum deflection of the plate.
