The stress-strain and curvature of the mid-plane

QUESTION 1
Using the stress-strain and curvature of the mid-plane in sections of a thin plate parallel to XZ and YZ planes, write the Equations for the Stresses in X and Y directions. Explain all the terms in the expressions.
QUESTION 2
A uniform load of 4KN/m2 is applied at the center of a spherical plate, fixed at the edge, of radius 1m thickness 3mm. Determine the deflection caused at the center by this load, using the given expressions. Take E for steel to be 205kn/mm2 and Poisson’s ratio ν as 0.3.
Fixing moment, M = (-pr^2)/8, Flextural Rigidity,D = (Eh^3)/12(1-ν^2 ) and deflection w = (pr^4)/(16D(1+ν))
