Answer:
A) i) Dynamic error ≈ 3.1%
ii) phase shift ≈ -12°
B) 79971.89 rad/s
Explanation:
Given data :
Damping ratio = 0.5
natural frequency = 18,000 Hz
<u>a) Calculate the dynamic error and phase shift in accelerometer output at an impart vibration of 4500 Hz</u>
i) Dynamic error
This can be calculated using magnitude ratio formula attached below is the solution
dynamic error ≈ 3.1%
ii) phase shift
This phase shift can be calculated using frequency dependent phase shift formula
phase shift ≈ -12°
<u>B) Determine resonance frequency </u>
Wr = 2
( 18000 
) = 79971.89 rad/s
C) The maximum magnitude ratio that the system can achieve
E is the answer because there’s not enough information to answer the question
We use the kinematic equation,
Here, s is the distance traveled by elevator u is the initial velocity and t is time.
As elevator accelerates uniformly from rest to a speed of 2.5 m/s in 12 s, so
Thus, the distance the elevator travels during 12 s time is
Answer:
D). 
Explanation:
As we know that temperature scale is linear so we will have
now we have
so the relation between two scales is given as
now we know that in kelvin scale the absolute temperature is 600 K
so now we have
so correct answer is
D).
Hope this helps
