The transfer function of the mass-spring-damper system discussed above is determined to be: G(s) = X(s) F(s) = 100 s²+5s+100 where x(t) is the displacement of the mass and f(t) is an arbitrary force input. We wish to study how the system responds to changing the frequency of the input, w when the forcing function is a sinusoid f(t) = A sin(wt) with A = 2. As part of your analysis, the following is requested:

Transcribed Image Text:2 Problem The transfer function of the mass-spring-damper system discussed above is determined to be: G(s) - X(s) F(s) = 100 s²+5s+100 where x(t) is the displacement of the mass and f(t) is an arbitrary force input. We wish to study how the system responds to changing the frequency of the input, w when the forcing function is a sinusoid f(t) = A sin(wt) with A = 2. As part of your analysis, the following is requested:
1. Find an analytical expression for the sinusoidal transfer function and simplify it such that
it has real and imaginary part in the form:
G(iw) Gx+iGy
=
(In other words, ensure there are no complex numbers in the denominator.)
2. Find an analytical expression for the the steady-state output-input ratio as a function of
frequency |G(iw)|
3. Find an analytical expression for the phase of the response, &, as a function of frequency
4. Write an expression for the steady state response, x(t), as a function of frequency using
your answers above. The only variables on the right-hand-side of your expression should
be w and t.
