For a ring of mass m and radius straight r connected to a thin rod, the total moment of inertia about an axis is .
<h3>What is a moment of inertia?</h3>
The sum of the products of the mass of each particle in the body with the square of its distance from the axis of rotation expresses a body's tendency to resist angular acceleration.
The given data in the problem is;
m is the ring's mass.
r is the radius of a ring.
L is the rod length = 2r
The total Moment of Inertia about an axis;
According to the parallel axis theorem,
The total Moment of Inertia about an axis will be;
Hence for a ring of mass m and radius straight r connected to a thin rod, the total moment of inertia about an axis is .
