I have done a simple resonant frequency analysis on a simply supported cantilevered beam. I think I have approached this problem correct, and according to the attachment, the frequency ended up being 89.4 Hz. Once I "found" this frequency, how do I continue and find the amplitude of this resonant frequency? How do I calculate other modes? It has been a while since I have done a vibration calculation (actually brushed on it in college and haven't touched it since)!
See attachment.

Thanks in Advance!
