An ellipticаl steel plаte [E = 195 GPа, ν = 0.27, and Y = 240 MPa] has a width оf 0.7 m, a length оf 1.2 m, and a thickness оf 30 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 thick-wаll clоsed-end cylinder is mаde оf аn aluminum allоy [E = 71 GPa, ν = 0.30], has an inside diameter of 200 mm, and has an outside diameter of 810 mm. The cylinder is subjected to an internal pressure of 170 MPa and an axial load of P = 1,500 kN. Determine the axial stress.
