For the same system, the damped natural frequency can be greater than the undamped natural O a False Ob True.
To double the undamped natural frequency of a mass-spring system, we must: O a. Divide the mass by 2 O b. Divide the mass by 4. O c. Multiply the mass by 4. Od Multiply the mass by 2
Spring-Mass-Damper System is consider as critically damped system if the damping ratio is equal O a 2 O b. 1 OC 0. Od 4.
Spring-Mass-Damper System will have vibration if the damping ratio is: O a Smaller than 1. O b. Greater than 1. Oc. Infinite number Od Zero
In forced vibration system with sinusoidal input, the resonance occur when: O a the sinusoidal input is having an infinite angular frequency O b. the sinusoidal input is having an angular frequency equal to the natural frequency O c. the sinusoidal input is having an angular frequency equal to zero. Od the sinusoidal input is having an angular frequency equal to 1.
