This equation for stress computes the radial stress (`sigma_r`) on the inner wall of a cylindrical pressure vessel.¹ The radial stress is same around the inner circumference of the wall of a cylinder. For this equation the outer pressure is assumed to be` P_o = 0`.

Inputs

The stress is computed from:

• P - the pressure inside the closed cylinder
