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
