Rotation of a meridian from its unloaded position

Rotation of a meridian from its unloaded position

Where used:
E = Modulus of Elasticity (lbs/in2)
v = Poisson's ratio
P = Total force applied (lbs)
σ1,2 = Stress, (lbs/in2)
R2 = Radius (in)
R = Distance as indicated (in)
y = Depth as indicated (in), Must be equal too or less than d
t = Wall thickness (in)
θ = Angle (deg.)
θo = Angle (deg.)
ψ = Rotation of a meridian from its unloaded position, positive when that meridional rotation represents an increase in ΔR when y or θ increases;

(Note: θo is the angle to the lower edge and cannot go to zero without local bending occurring in the shell)
