A 40 kg mass is supported on four (4) similar mountings as in vibrator accelerometer Fig.Q14.1. A vibrator is then used to provide a sinusoidal force 40 kg P = 200 sin 50t N. It was found that the amplitude of the force Force transducer transmitted to the floor measured by the force transducer, is 200 N and mountings the steady- state amplitude of the mass is 1.8 mm. Find the stiffness and the damping coefficient for the mountings. FIG. Q 14.1
