A general basic vibratory system consists of mass and spring.Figure Q1 shows the vibration knowledge application of multipleparallel springs installed in between the Caterpillar diesel enginegenerator and the foundation slab (inside the red dash box). Giventhat the mass of the diesel engine generator is W =450 kg, the spring equivalent stiffness iskeq = 1.5x106 N/m andthe generator revolution per minute is RPM =3300 RPM. Assume that the system is a single degreeof freedom and undergoes only vertical translationalmovement.

(ii) Compare the value of spring displacement, x for the freevibration and force vibration of 10 kN if the diesel enginegenerator excites 1 m/s2 during operation. Neglect thegravitational effect. (8 marks)
(iii) Determine the number of cycles per second for the dieselengine generator. (2 marks)
