Meridional Stress

Circumferential Hoop Stress

Radial Displacement of Circumference

Rotation of a meridian from its unloaded position

Where used:

E = Modulus of Elasticity (lbs/in^{2})

*v* = Poisson's ratio

q = Force applied (lbs/in)

σ_{1,2} = Stress, (lbs/in^{2})

R_{1} = Radius (in)

R_{2} = Radius (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;
