Question

Is it possible to design a vibrometer with a mass m-0.003kg that can effectively measure displacements at 2 KHz if the total allowable travel space within the sensor is 0.04 mm? Justify your answer. 7. A Front loading washing machine weighing 180 kg operates at 50 rpm, the 8,

Answer 1

It is a very simple problem Since it is a static are so we can use Right Method From that w = squareroot 9/8 where w = circular frequency = 9.81/0.04 times 10 6 -3 = 495.22 rad/s Now f = w/2 pi = 495.22/2 times pi = 78.81 Hg 78.81 Hg is the maximum lens but given frequency is 2 kHz so 78.81 less than 2 k H z This system cannot measured this frequency
