I'm working on an analysis problem using Abaqus. I would like to compare my results with an exact equation. My problem is modeled as a simply supported beam with a lumped mass at the end. The equation that I'm using for the exact solution is as follows:(adsbygoogle = window.adsbygoogle || []).push({});

k=3EI/L^{3}

ω_{n}=[itex]\sqrt{k/(M + 0.23m)}[/itex]

How do I incorporate the mode number to find what the exact solution is at say mode 2 or 3?
