+b=-2.93*10**-3

+y_c=3*P*L**3*(8*n*E*b*t**3)**-1 //Deflection (//Equation 1)
+sigma=3*P*L*(2*n*b*t**2)**-1 //stress
+//Dividing Equation 1 by Equation 2 we get
+//y_c*sigma**-1=L**2*(4*E*t)**-1
+//After substituting values in above equation and further simplifying we get
+t=190*10**6*0.7**2*(1.8*10**-2*4*200*10**9)**-1*10**3 //thickness of plate
+b=12*t //Width of plates
+
+//sigma=3*2**-1*P*L*(n*b*t**2)**-1 //stress
+//After substituting values in above equation and further simplifying we get
+n=3*3.5*10**3*0.7*(2*190*10**6*0.077583*(6.465*10**-3)**2)**-1
+
+//Now sigma*y**-1=E*R**-1 
+//simplifying above equationwe get
+R=200*10**9*6.465*10**-3*(2*190*10**6)**-1 //Radius of Curvature
+a=L*10**-2*(2*n)**-1*10**3 //Overlap
