If the difference between the maximum and the minimum recorded values in 8mm, Find the amplitude of motion of the vibrating structure when its frequency is 40 rad/sec.

$w_n = 4r/sec$

$\xi$ = 0.2

W = 40 rad/sec

2Z = 0.0008 m

= 0.004m

enter image description here

Y = ?

$\frac{Z}{Y} = \frac{ …
