Case 5: vibration measuring instrument.
1] Seismic instrument [vibrometer]
outputinput=zy=r2√(1−r2)2+(2ζr)2
Experimental value
R = 0 to 0.3 un damped accelerometer
R = 0.3 to 0.7 damped
R = 1 velometer
R = 3 to 7 vibrometer.
2] Velometer → zy.r=r√(1−r2)2+(2ζr)2
zy.wwn=r√1−r2)2+(2ζr)2
Z.wny.w=r√(1−r2)2+(2ζr)2
zy=r√(1−r2)2+(2ζr)2
3] Accelerometer → zy.r2=1√(1−r2)2+(2ζr)2
wn2.7w2.y=1√(1−r2)2+(2ζr)2
zy=1√(1−r2)2+(2ζr)2
