2. A point mass m is strung on a vertical ring of radius R, and it oscillates freely with respect to its equilibrium point located at the lowest point of the ring. An external moment of force is applied that causes the ring to oscillate about its center in the form α =α cost where a is the angle of rotation. Determine the general movement of the mass m, and under what circumstances this movement enters into resonance, detailing this phenomenon.

Forced undamped vibrations

In mechanical engineering, vibration is expressed as the term that occurs due to an object's backward and forward movement about a point of equilibrium. Generally, there are three types of vibrations which are,

A thin, circular ring of mass m and radius r is suspended at 0. Determine the natural frequency of small oscillations of this ring in the xy plan. y Hint: The moment of inertia of a thin, circular ring of mass m and radius r about its central axis is I = mr². In this problem, the ring rotates about point 0; therefore, we need to use the Parallel Axis Theorem.
