WebFor this calculation, we will use an internal radius r1and external radius r2. As we know the moment of inertia is incomplete without the mass M so we will be using it as well. So, the final equation we get is as follows: I= 1 ⁄ 2 M (r2² + r1²) Likewise, we can also get the moment of inertia of a hollow cylinder with a thin wall; I=Mr². WebThe classic equation for hoop stress created by an internal pressure on a thin wall cylindrical pressure vessel is given in Eq. (1.6): (1.6) where P, the internal pressure; t, the wall thickness; r, the radius of the cylinder. The SI unit for P is Pascal, while t and r are in meters.
