You need to run some vibrations tests and your lab has an accelerometer (2nd order system) that has a natural frequency (resonance) at 3,000 Hz and damping ratio of 0.05. The vibrations you wish to measure are in the range of 100 - 1,200 Hz. a. What are the amplitude error (in %) and phase shift (in degrees) expected at the upper end of the vibration frequency range (1,200 Hz)? b. What is the maximum frequency that you can measure to have no more than 1% error in the amplitude of the reading? c. Is this a suitable choice of accelerometer for this measurement? Why or why not?

QUESTION 4 The amplitude of vibration of an undamped system is measured to be 1 mm. The phase shift from t=0 is measured to be 2 rad and the natural frequency is found to be 5 rad/s. a) Calculate the initial conditions (x(0) and v(0)) that caused this vibration to occur. Assume the response is of the form x(t) = Asin(wnt + p). b) Sketch its position in relation with time.

It was found that viībration improves or contributes also to the effciency of certain industrial processes. 3. If the system is damped, some energy is stored in each cycle of vibration and must be replaced by an external source if a state of steady vibration is to be maintained. 4. Basically, the oscillation of a pendulum would naturally stop due to the resistance offered by the gravity. 5. The work done in deforming a spring is stored as strain or potential energy is represented by the area of a triangle. 6. In an octave band, it can be…
