Answer:
The maximum acceleration amplitude is 40.28 g.s.
Explanation:
Given that,
Full scale suspension = 25 mm
Frequency = 20 Hz
We need to calculate the maximum frequency
Using formula of maximum frequency
Put the value into the formula
We need to calculate the maximum acceleration amplitude
Using restoring force
Using equation of S.H.M
On differentiating
On differentiating again
Maximum acceleration =ω²A
Which is at the maximum amplitude
Hence, The maximum acceleration amplitude is 40.28 g.s.
