How can I plot this amplification diagram?

I have to plot the amplification diagram of a nonlinear mechanical system which has harmonic excitation. The amplitude of the system can be calculated by solving the following equation:
where μ and ω are known system parameters, A is the amplitude of the system, is a proportional parameter to the amplitude of the harmonic excitation, Ω is the angular frequency of the harmonic excitation.
I have to plot the amplification diagram, which means I have to plot this equation on the plane (Yes, A is between absolute value brackets).
How can I do that. is arbitrary positive.

Hi,
As per my understanding you are trying to plot two variables Ω and |A| based on the fo value that you want to give parametrically. Since you want to visualize it as a diagram there need to be a limit placed on Ω and A for plotting.
Similarly, I assume fo is independent of Ω and A so instead of giving a single value of fo to plot I suggest plotting it in a specific range using fimplicit3. In this you may define the given equation which have three variables (Ω, A and fo) and mention the interval in which you want to plot.
As darova pointed in the comments that even if fo is parametric, for showing the equation on a graph it requires some values so that different curve can be visualized for fo values.
Hope it helps.
