Rearrange Equation to find unknown variable #260

Closed sapmaskey closed 4 months ago

sapmaskey commented 4 months ago

Would it be possible to rearrange an equation to report unknown variable?

For example: Phi = 0.9 Mn = 100 kip.ft Fy = 50 ksi PhiMn = FyZx Zx = ?

This could be helpful for longer equations.

Please point me to the post if this already a feature.

Thanks for your time.

Hi!

If you mean to solve for the variable Zx symbolically and get Zx = Phi*Mn/Fy, Calcpad cannot do that. It is a numerical package and does not include symbolic evaluations. It can only calculate the formulas you enter in the code.

We do not plan to develop a symbolic engine. It is a huge task and there are many symbolic CAS's already available.
