See lessMoment of inertia of a ring of mass M and radius R about an axis passing through the centre and perpendicular to the plane is l. What is the moment of inertia about its diameter?
The moment of inertia about the axis of rotation is merely a function of the distribution of its mass with regards to that axis; for a given mass and radius for a ring, it represents how the same mass is concentrated at the distance uniformly distributed from its center. However, if we were to consiRead more
The moment of inertia about the axis of rotation is merely a function of the distribution of its mass with regards to that axis; for a given mass and radius for a ring, it represents how the same mass is concentrated at the distance uniformly distributed from its center. However, if we were to consider it about one of its diameters, things would change based upon the principles of rotational dynamics.
By the perpendicular axes theorem, for any planar object, the moment of inertia about an axis perpendicular to its plane equals the sum of its moments of inertia about two mutually perpendicular axes lying in the plane and passing through the same point. In the case of a ring, the two perpendicular axes in its plane are its diameters, and they are identical due to symmetry. Therefore, the moment of inertia about a single diameter is half of that about the perpendicular axis through its center.
This relation further shows that moment of inertia is dependent on the geometry as well as the orientation of the axis of rotation. For the ring, the moment of inertia about its diameter comes out to be half the moment of inertia.

The angular momentum of a moving body remains unchanged unless an external torque is exerted on the moving body. Angular momentum denotes rotational motion around the axis in any object depending upon its distribution of mass and rotation velocity. By principle, there would be a lack of a change in time with respect to total angular momentum when no torque external to a system is given to it.
Rotational force, referred to as torque, affects the angular momentum due to a change in speed of rotation or rotation direction. With the application of external torque in a body, its angular momentum changes. Nonetheless, if torque is not external, the angular momentum remains unaffected, and its rotational motion keeps constant.
This concept is evident in various situations. For example, a figure skater spinning faster by pulling their arms inward demonstrates conservation of angular momentum. The skater changes the distribution of mass in their body without involving any external torque. Similarly, planets orbiting the Sun conserve their angular momentum because no external torque significantly affects their motion.
In essence, angular momentum remains constant only when there is no external torque; it ensures steady rotational motion. Therefore, a moving body will retain its angular momentum if no external torque is applied.

We can look at the forces acting on the sphere to find the linear acceleration of a solid sphere rolling down an inclined plane set at an angle of 30 degrees with the horizontal. The main forces are the gravitational force, which is the cause of the motion of the sphere, and the frictional force, which is required for rolling motion.
When the sphere rolls down the incline, gravity pulls it down, but the angle of the incline determines how this force is distributed. The gravitational force can be divided into two components: one that acts parallel to the slope, propelling the sphere downwards, and another that acts perpendicular to the slope, influencing the normal force experienced by the sphere.
As the sphere rolls without slipping, it is undergoing both translation and rotation simultaneously. The resulting linear acceleration would then be developed from the motion dynamics of a rolling sphere.
For a solid sphere rolling on a 30-degree incline, the acceleration in the line of motion ends up being just some fraction of g, weighted by the sine of the angle of inclination. In this problem, the specified conditions allow calculating the acceleration as the sphere rolls down the ramp to be 5g/14, so this is the right solution.
