Moment of Inertia in different bodies

Different rigid bodies have different values of the moment of inertia and hence different formulas to calculate it. Also, the Moment of Inertia in a body depends upon the axis of rotation. So here is a table of moment of inertia in different bodies depending upon the axis of rotation.

S.NRigid Bodyaxis of rotationMoment of Inertia
1.thin rodperpendicular to its plane and passing through a centerI = \frac{1}{12}ML^2
2.thin rodperpendicular to its plane and passing through one endI = \frac{1}{3}ML^2
3. circular ringperpendicular to its plane and passing through a centerI = MR^2
4.circular ringabout any diameterI = \frac{1}{2}MR^2
5.circular ringin a plane about any tangent I = \frac{3}{2}MR^2
6. circular diskperpendicular to its plane and passing through a centerI = \frac{1}{2}MR^2
7. circular diskabout any diameterI = \frac{1}{4}MR^2
8. circular diskabout any tangent in a planeI = \frac{5}{4}MR^2
9. rectangular laminaperpendicular to its plane and passing through its centerI = \frac{1}{12}M\left(l^2 + b^2 \right)
10rectangular laminaaxis along the edge of the lengthI = \frac{1}{3}Mb^2
11.solid spherethrough its centerI = \frac{2}{5}MR^2
12. solid sphereabout any tangentI = \frac{7}{5}MR^2
13.hollow spherethrough its centerI = \frac{2}{3}MR^2
14.hollow sphereabout any tangentI = \frac{5}{3}MR^2
15.solid cylinderabout any symmetry axisI = \frac{1}{2}MR^2
16.hollow cylinderabout its axisI = MR^2
