The amplitude of the output vibration is equal to the input vibration (i.e. T= 1) when the frequency of excitation, w=V2w | B. Increased damping does not change the vibration isolation efficiency at high frequencies (r> 1). C. The amplitude of the output vibration is less than the input vibration at all frequencies above the resonant frequency. D. Increased damping reduces the frequency of the peak transmissibility amplitude. A Moving to another question will save this response.
Question 3 Consider these 3 statements: 1. Over time, the total energy of a conservative system may increase but cannot decrease. ii. When driven by a time-varying force f(t), the motion of a linear mass-spring-damper system will be sinusoidal, irrespective of the form off (t). iii. Typically, the addition of an undamped vibration absorber to a single degree of freedom system will largely eliminate one natural frequency but create two new ones. Which of the following are correct? Select one answer only. O A. Only (iii) O B. (ii) & (111) OC.() & (ii) O D. None of them.
