A square steel plate 2 m × 2 m and 10 mm thick at the bottom of a tank must support salt water at a height of 3 m, as shown in Figure P12-11. Assume the plate to be built in (fixed all around). The plate allowable stress is 100 MPa. Let E = 200 GPa, v = 0.3 for the steel properties. The weight density of salt water is 10.054 kN/m3. Determine the maximum principal stress in the plate and compare to the yield strength.
