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 =400 kg, thespring equivalent stiffness is keq = 1 x 10^6 N/m and thegenerator revolution per minute is RPM = 3700 RPM. Assume thatthe system is a single degree of freedom and undergoes onlyvertical translational movement.
1.Sketch free body diagram of the system together with theaction and reaction force magnitude and direction
2.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.
3.Determine the number of cycles per second for the dieselengine generator
