Re: phi in both sides of formula 14-1

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Eugenio:
   You are misinterpreting the equation.  It's not an algebra type equation that
you solve for Pnw.  The design axial strength is phi(Pnw) and to calculate this
you evaluate the right side of the formula.

   I hope that makes sense.
