What is the physical meaning of each term in the parallel-axis theorem?
I=I com +Mh^2
I=I com +Mh^2
Not sure what you mean by 'physical' meaning, but:Duane said:What is the physical meaning of each term in the parallel-axis theorem?
I=I com +Mh^2
Icom is the moment of inertia of an object about an axis through the centre of mass. I is the moment of inertia of the object about an axis that is parallel to the axis through the centre of mass (com) and separated from it by a distance h. M is the mass of the object.Duane said:What is the physical meaning of each term in the parallel-axis theorem?

The Parallel-axis theorem, also known as the Huygens-Steiner theorem, is a mathematical law that relates the moment of inertia of a body about an axis parallel to its center of mass to the moment of inertia of the same body about an axis through its center of mass.
The Parallel-axis theorem can be calculated using the formula I = I_{cm} + md^{2}, where I is the moment of inertia about the parallel axis, I_{cm} is the moment of inertia about the center of mass, m is the mass of the body, and d is the distance between the two axes.
The Parallel-axis theorem is an important concept in physics and engineering, as it allows for the calculation of the moment of inertia of an object about any axis, not just the center of mass. This is useful in various applications such as calculating the stability of structures and predicting the behavior of rotating objects.
Yes, the Parallel-axis theorem can be applied to any rigid body, regardless of its shape or size. It is a fundamental law of physics that holds true for all objects.
The Parallel-axis theorem is directly related to rotational motion, as it allows for the calculation of the moment of inertia, which is a crucial parameter in rotational dynamics. It is used to determine the resistance of an object to changes in its rotational motion.
