Rotation of a meridian from its unloaded position
ψ = 0

Where used:
E = Modulus of Elasticity (lbs/in2)
v = Poisson's ratio
q = Applied pressure (lbs/in2)
σ1,2 = Stress, (lbs/in2)
R2 = Radius (in)
R = Distance as indicated (in)
t = Wall thickness (in)
θ = 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;
