Q. In vibration analysis 'Beat' frequency is (Solved)
1. The frequency at which vibrations of a system are damped
2. Said to occur when two vibrations of almost equal frequency are present
3. The frequency when a system exceeds the vibrations frequency from the critical value
4. The frequency below which vibrations do not cause appreciable damage to equipment
5. One at which the vibrations of a system act exactly opposite to the other thereby causing damping
- b. Said to occur when two vibrations of almost equal frequency are present
