2 criticalF m 2m2 A) For a frictionless system, resonance occurs when the system is driven at the natural frequency wo vk/m. If we take the friction out of the spring-mass system. we're studying, we have m 1 and k 26 still. Calculate the natural frequency of this frictionless system, compare it to the critical driving frequency for the system with friction included, and draw a conclusion about the effect of friction on the frequency at which resonance occurs. B)...
1. Oscillating system performs damped oscillations with frequency 1000 Hz. Determine the frequency of natural oscillations if the resonance frequency is 998 Hz. 2. Amplitude of vibrations during 5 minutes decreased by 2 times, during which time the amplitude reduced by 8 times? 3. For 8 minutes amplitude decreased 8 times. Find damping factor. 4. Determine how much resonance frequency is different from the natural oscillation frequency (1kHz) when the damping factor is 400 s decreased 20 times 6. The...
Problem 17. A) In steady state, does a damped, driven oscillator oscillate at the frequency of the driving force, the natural frequency of the oscillator or neither of these frequencies? B) Ella Fitzgerald could break a wine glass with her voice but Louis Armstrong could not. Is this likely because Ella could sing louder than Louis? Justify your answer. C) What happens to the width of the average-power-delivered vs driving frequency curve if the damping is increased? D) What happens...
A 290-g mass is attached to a spring. Its natural angular frequency is 69 rad/s, and it is in a damping medium. At what angular frequency should it be driven so its speed is a maximum? Answer in rad/s.
