### Dynamics of Rotational Motion: Rotational Inertia | Physics

That is, rF = mr2α. or. τ = mr2α. This last equation is the rotational analog of Newton's second law ( F = ma ) where torque is analogous to force, angular acceleration is analogous to translational acceleration, and mr2 is analogous to mass (or inertia). The quantity mr2 is called the rotational inertia or moment of inertia of a point ...

### Chapter 9 Rotation - nhvweb.net

theory works in terms of the moment of inertia, angular acceleration, and torque of the bat. Determine the Concept The closer the rotation axis to the center of mass, the smaller the moment of inertia of the bat. By choking up, you are rotating the bat about an axis closer to the center of mass, thus reducing the bat's moment of inertia.

### What Is Moment of Inertia in Physics? - ThoughtCo.com

Apr 21, 2019· The moment of inertia of an object is a calculated measure for a rigid body that is undergoing rotational motion around a fixed axis: that is to say, it measures how difficult it would be to change an object's current rotational speed. That measurement is calculated based upon the distribution of mass within the object and the position of the axis, meaning that the same object can have very ...

### MIG Problems and Remedies - Lincoln Electric

Some wire feeding problems occur because the inertia from the wire reel causes it to coast after the gun trigger is released. Remedy If the reel continues to coast, the wire on the reel will loosen and the wire may come off or become tangled. Most wire feeding systems have an adjustable brake on the wire reel.

### Moment of Inertia

• The moment of inertia (MI) of a plane area about an axis normal to the plane is equal to the sum of the moments of inertia about any two mutually perpendicular axes lying in the plane and passing through the given axis. • That means the Moment of Inertia I z = I x +I y.
