The Hollow Cylinder Moment of Inertia calculator computes the MOI of a hollow cylinder about a central axis based on the mass and dimensions of a hollow cylinder.

INSTRUCTIONS: Choose units and enter the following:

• (m) Mass of Hollow Cylinder
• (R1) Inner Radius
• (R2) Outer Radius

Moment of Inertia (MOI): The moment of inertia is returned in kilogram⋅meters squared (kg·m²).

The Math / Science

The formula for the moment of inertia for a Hollow Cylinder is:

I = 1/2 m ( ri² + ro²)        

 where

• m = mass of hollow cylinder
• R1 = distance between axis and inside of hollow cylinder
• R2 = distance between axis and outside of hollow cylinder
