For this question 3, this is part 2

20 ' kg was observed to vibrate badly at frequency
A mass of flexible machine part, m, of
of 10 Hz. The vibration was caused by the application of a harmonic force, F of
the flexible part. A judgment was made by a mechanical engineer that the vibration was
excessive because the frequency of the harmonic force coincides with the natural frequency
of the flexible part.
100 N to
(d)
If the flexible machine part is operated in the speed range of 500 to 750 rpm, justify
whether the design of vibration absorber in Q3(c) is safe to be used or not.
