Linearly Varying Radial Pressure

Meridional Stress

Circumferential or Hoop Stress

Radial Displacement of Circumference

Change in height dimension y

Rotation of a meridian from its unloaded position

Where used:

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

v = Poisson's ratio

σ_{1,2} = stress, (lbs/in^{2})

t = Cylinder thickness, (in)

l = Length of cylinder, (in)

y = Length of linearly increasing load, (in)

R = Radius, (in)

q = Applied unit load (lbs/in^{2})

q_{o} = Peak applied unit load (lbs/in^{2})

ψ = Rotation of a meridian from its unloaded position, positive when that meridional rotation represents an increase in ΔR when y or θ increases;
