Multivariable algebrain equations
Multivariable algebrain equations
(OP)
I'm trying to do Castigliano's theorem in Mathcad. Integrating in Mathcad is pretty easy, but is there a way to implicitly define functions?
For example, I would like to be able to enter
-M + F*0.026m + Q*0.036m = 0
(which is a force balance on a free body diagram)
and let Mathcad turn the above expression into
M = F*0.026m + Q*0.036m
so that it's an explicit expression for M, a moment term.
Is this possible? Or do I have to write out the steps manually?

RE: Multivariable algebrain equations
1) Write out your original expression, using the Ctrl= (the bold equal sign).
2) Highlight the variable you are interested in solving for.
3) Select Symbolics -> Variable -> Solve
4) Mathcad will display the solution. You will have to provide the "M :=" at the beginning of it.
Good luck

But is it possible to make Mathcad define the separated variable M as the explicit function? I'd like Mathcad to output something like
M(Q) = F*0.026m + Q*0.036m
where F is a constant.
Doing it by hand is like 1 extra line, but it would look a lot cleaner if I could do it automatically.
Also, what's the function of the Boolean equal sign here? I don't understand how to use them.

Great solution - I was not familiar with live symbolics 'til you showed it in your worksheet.
