There is an analogous equation for rotary motion. We have T = J*Θ where “T” is the torque applied to some object having a moment of inertia “J” which experiences a rotary acceleration called “Θ” which ...

The area moment of inertia (also called the second moment of area) defines the resistance of a cross-section to bending, due ...

Moment of inertia is different than mass, ... This equation says – take each mass. Multiply the mass by the distance to the axis squared and add up all these terms.
