The Moment of Inertia of an Annulus calculators computes the moment of inertia of an annulus of uniform density with outer radius a and inner radius b about an axis along a diameter of the annulus.
INSTRUCTIONS: Choose the preferred units and enter the following:
Moment of Inertial (MoI): The moment of inertia is returned in kg•m².
The amount of torque needed to cause any given angular acceleration (the rate of change in angular velocity) is proportional to the moment of inertia of the body.
