6. Circular plates
A circular plate 120mm diameter and 10mm thick is constructed from steel E = 208GN/m2 and  = The plate is subjected to a pressure of 5 MN/m2 on one side. Determine:
(a)   the maximum deflection clamped at the edges
(b)   the maximum deflection simply supported at the edges.
(c)   The maximum radial stress (a)

7. Circular plate with central piston
A circular dish 150mm in diameter and 12mm thickness is clamped around the periphery and built into a piston of diameter 60mm at the centre, assuming that the piston remains rigid determine the maximum deflection of the disk when the piston carries a load of 5kN.
E = 208 GN/m2
 = [0.0035mm]
