As Valery already pointed out - look at your definition of lambda - is this really what you intended?

My first guess was that you had a unit mis-match,especially after reading Luc's rant about lambda, but you don't.
Prime is notorious for getting the "labels" wrong. It's possible (in Prime) to have two things look exactly or nearly the same and be different things; you can have a variable m and it can be six meters long and write m := 6 m. If the first is labeled "variable" or "-", and the second is "unit" Prime will happily continue. But if you created something in the red rectangle with one label, and in the rectangle it has a different label, Prime will refuse to continue.
Check that.
if not wrong, You refer this.
The problem that you can't solve it because shear stress. just put psi because it from testing and result with square root but it keeping still Stress unit .
Hope it useful.
Yes, as Fred already wrote its an interesting workaround to be able to use an empiric formula where f is expected in psi and the square root of it is taken.
Guess most of us would have done it the "usual" way: remove the unit by dividing by the asked for unit, do the calculation (root) and then add the proper unit.
