WebThird, in case of forced vibrations the dam was considered as an elastic body, hence, as a result plastic deformations occurring in the body were neglected. In consequence of this the degree of the dam stability reliability was artificially increased. WebAny forced oscillation consists of two distinct regimes: An initial transient period during which the oscillations are established, and A steady state period during which the oscillations have constant amplitude and a frequency equal to the driving frequency, ω ω.

Forced Oscillations, Free Oscillations, and Resonance

WebExplanation: The phenomenon of oscillation with improved amplitude when the frequency of the forced oscillator is near to natural frequency is known as resonance. Hence, the vibrations of the external oscillator that match the vibrations of particles that oscillate are the reason for this increase. Thus, there is a net increase in vibrations. WebJun 16, 2024 · (a) In forced oscillations, a body oscillates under the effect of an external periodic force of frequency other than its natural frequency. (b) In resonant oscillations, the frequency of the periodic force is always equal to natural frequency of oscillation of the object. Answer. Answer: (a) True (b) True optics cylance
