Question

For a natural frequency of 100 Hz, and a damping ratio of 0.7, compute the input
frequency range for which the system in the figure will have an amplitude ratio of
1±0.01.

Answer 1

Answer:

Write the equation of the amplitude ratio.

…… (1)

Here, initial force is , spring constant is , input frequency is , natural frequency is, mechanical friction is c, and critical damping factor is .

Substitute 100 Hz for and 0.7 for in Equation (1).
