SMath Solver Problem 1

[dik]

Any idea of why the following gives a No Real Root Error?

maybe better to attach the input file.....

 

[dik]

Sure.... thought the beginning program was pretty simple...

Deleting out the units from all of the variables (q, L) allow the solve command to run. I'm not sure why the units are stopping the solve command from working, it looked like they were balanced to me. I believe that's where the error is though.

Shotzie... will try that... units are balanced but could be a program issue. Thanks...

Mathcad had similar issues with units; some functions operated perfectly well with units and others, not so well.

TTFN (ta ta for now)
I can do absolutely anything. I'm an expert!

Thanks, Dik

Thanks IRS... that was the case for the solve.

After skimming this forum post Link it appears that adding 'ft to the x variable will allow the solve command to run, although I don't believe it will assign units to the "res" variable you've set. I've updated your previously attached file with the change. Not sure if this is the best way to solve the problem but seems to be a workaround for now.

will try that... again, thanks

Nope... current edition attached.

Shotzie... missed that, thanks.
