I'm solving the natural frequency of a structure. Pleas help. See attached file. How to do this in Mathcad Prime 3.0?
I can't do it in Prime (limited by Express), but here's how to do it (Using Mathcad 11), Prime should be similar.
Your problem is like:
Then to solve for omega:
Success!
Luc
on the other side, results:
So, what is the solution? Who knows?
Luc showed one way and this seems to answer your question about solving for a variable used in a matrix.
It uses Mathcads symbolics because using a numeric solve block would only give you one solution, depending on a guess value.
For your specific example you could also use the built-in function "genvals".
Anyway I get quite the same results as Luc and they differ from the values given in your picture!??
