Question: a state the three steps to solve a vibration problem...

Question details

(a) State the three steps to solve a vibration problem (b) The period of vibration of the system shown in Fig. Q5 was observed to be 0.8 s. When block A was removed, the period becomes 0.7s. Determine the following: (i) (ii) The mass of block C The period of vibration if both blocks A and B are removed from the system. (c) A 20 kg flow measuring instrument is placed on a laboratory bench A pad of stiffness 200 kN/m and damping ratio 0.1 is placed between the apparatus and the bench. The bench is bolted to the laboratory floor which has a steady state amplitude of displacement vibration of 5 mm at a frequency of 30 Hz.Find: (i) The amplitude of displacement of the instrument (ii) The amplitude of acceleration of the instrument 3 ke Fig. Q5
