engineering recuitment GATE ME 2023-24 Test Series Mechanical Vibrations Forced Vibration Damping Coefficient and Damping Ratio
A spring-mass-damper system is subjected to excitation force with an amplitude of 240 N. The angular frequency of the force of excitation is 100 rad/s. The stiffness of the spring used in the system is 12.1 kN/m and the mass of the body attached to the spring and damper is 4 kg. The resonance amplitude of the mass is found to be 37.86 mm. The damping coefficient of the system will be ______ N.s/m.
