A single cylinder vertical petrol engine has a mass of 300 kg and is placed on a chair frame. The static deflection of the chair is given as 2.4 mm. The reciprocating mass of the engine is equals18 kg and the stroke of the engine is 100 mm. The dashpot connected has a damping coefficient of 4 N/mm/s. In steady state vibration, determine the amplitude of vibration (in mm) if the shaft rotates at 500 rpm.
