I can't solve the equation below, I tried two options but none worked. Someone could help?

Please: attach the document for the missing data.

Let's start by observing that:
1) the "solve" function is native to smath but does not accept units of measurement (if you want to use it you must temporarily get rid of the units of measurement)
2) the "FindRoot" function you have defined relies on "solve" (see above)
3) in the "nonlinear Solver" plugin you will find a "FindRoot" function that can do for you and that manages the units of measurement
4) there are other features and plugins that can help you. I suggest you also consult Martin Kraska's Interactive SMath Handbook with lots of information and practical examples (you can find it in the tool you use to install plugins)

Yes. It is attached or attached.Modelo_Planilha de Calculos_OM_rev02.sm (2 MiB) downloaded 35 time(s).

Thank you.

a quadratic equation, solved algebraically?

MPa^2=((σ.solda)/(a.cordao))^(2)+3*((P.total)/(2*h*a.cordao))^(2)

===>

sys(a.cordao≡-sqrt(4*h^2*σ.solda^2+3*P.total^2)/{2*MPa*h},a.cordao≡sqrt(4*h^2*σ.solda^2+3*P.total^2)/{2*MPa*h},2,1)
