List of top Mechanical Engineering Questions on Vibrations asked in CUET (PG)

For an underdamped system: A. Damping ratio is unity
B. Motion is periodic
C. System stop within least possible time
D. System vibrate at damped natural frequency

Assertion (A): Transmissibility is the ratio of force applied to the force transmitted.
Reason (R): Transmissibility is a measure of effectiveness of vibration isolating material.

What is the effect of mass of spring \(m_s\) on equivalent mass \(M\) of system with mass \(m\)?

The equation of free vibration of a system is \( X + 36\pi^2 X = 0 \). Its natural frequency is:

The undamped natural frequency of system is 80 rad/sec. A damper is provided in the system having damping factor 0.7. The damped natural frequency of the system in rad/sec will be:

A solid disc of mass \( m \), radius \( r \) is resting on a horizontal smooth surface. A spring of stiffness \( k \) is connected to the disc at distance \( e \) directly above the centre of the disc. Another end of the spring is connected to the vertical wall. For small angular displacement of the disc, the natural frequency of the system in radians per second will be:
