A circulаr steel plаte [E = 205 GPа, ν = 0.27, and Y = 300 MPa] with a central hоle is simply suppоrted at the central hоle, free at the outer edge, and uniformly loaded as indicated in Case 2. For the plate, a = 300 mm, r0 = 240 mm, h = 12 mm, and p = 70 kPa. Determine the maximum deflection of the plate.
