Solver App - Newbie needs help

[pinkman]

Hi,
The Solver App is a numerical Solver, it won’t rewrite expressions.

Can you give us a more precise expression of your equation?
Are Mz, Iz, Iy, Izy (...) variable? Or the constants and variables are M, I, y, z...?
The last part of the equation is (.../Izy)*My or (...)/(Izy*My)?

Thanks
