(I) Sketch free body diagram of the system together withthe action and reaction force magnitude and direction
(II) Compare the value of spring displacement, x for thefree vibration and force vibration of 10 kN if the diesel enginegenerator excites 1 m/s2 during operation. Neglect thegravitational effect.
(III) Determine the number of cycles per second for thediesel engine generator.
A general basic vibratory system consists of mass and spring. Figure Q1 shows the vibration knowledge application of multiple parallel springs installed in between the Caterpillar diesel engine generator and the foundation slab (inside the red dash box). Given that the mass of the diesel engine generator is W=Qkg, the spring equivalent stiffness is keq=RN/m and the generator revolution per minute is RPM=S RPM. Assume that the system is a single degree of freedom and undergoes only vertical translational movement.
