Solving quadratic equation

[ptc-5120737]

I'm having some problems solving a quadratic equation. It's telling me one of my values should be a scalar, but I had units in functions before. I've attached the problem. Basically, I want to get my positive root (should be in length units) out of this, which represent depth to the netural axis of my section.

Thanks

I figured it out. Should have been A.c(c.s) in the function definition.

Noel,

For completeness I would suggest uploading the worksheet with the solution in.
