haruspex said:It doesn't seem to me that it would be a useful approach. It does not simplify anything. You need to slice it into elements that have an easily calculated MI, such as discs perpendicular to the axis of rotation.

Welcome to Physics Forums,
Have you tried it? You must show what you have tried to get help on PF (forum rules).

chocophysuny said:"To find MI from the element, we need element of volume and element of MI, isn't it?"
chocophysuny said:But my lecture say this method is easy enough to solve.
And, actually i confused to find the element of volume and element of MI.
So, in your opinion, this is not solvable?
The "Proofing Moment of Inertia Solid Sphere" is a physical property that describes how an object's mass is distributed around its rotational axis. It is a measure of an object's resistance to changes in its rotational motion.
The formula for calculating the "Proofing Moment of Inertia Solid Sphere" is I = 2/5 * mr², where I is the moment of inertia, m is the mass of the object, and r is the radius of the object.
The "Proofing Moment of Inertia Solid Sphere" is important in physics because it helps us understand and predict an object's rotational motion. It is also used in the design and engineering of various objects, such as wheels, gears, and flywheels.
The "Proofing Moment of Inertia Solid Sphere" can be measured or determined experimentally by using various methods such as the torsion pendulum, compound pendulum, or parallel-axis theorem. These methods involve measuring the object's period of oscillation or its mass and distance from the axis of rotation.
The "Proofing Moment of Inertia Solid Sphere" and the "Proofing Moment of Inertia Hollow Sphere" differ in that the solid sphere has a higher moment of inertia compared to the hollow sphere of the same mass and radius. This is because the mass is distributed farther from the axis of rotation in a solid sphere, resulting in a greater resistance to changes in rotational motion.
