In case of forced oscillation of a body
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. WebBalloon pumps are employed to assist cardiac function in cases of acute myocardial infarction, ventricular arrhythmias, cardiogenic shock, unstable angina, refractory ventricular failure, or cardiac surgery. Counterpulsation, through increasing the diastolic pressure and reducing the systolic pressure, increases coronary perfusion and assists the heart to …

Web(iv ) Forced oscillations. When a vibrating body is maintained in the state of vibration by a periodic force of frequency (n) other than its natural frequency of the body, the vibrations are called forced vibrations. ... In the case of forced vibration, if the frequency difference is small, the amplitude will be large (Fig.). 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.
