I am trying to solve an equation using find but it seems not working. it says that "this variable is undefined". Really appreciate your help. The file is attached.
With Find you need a Given, together with an initial guess for M. However, that still doesn't seem to work here (doesn't want to converge to a solution. Luckily this is easy to represent as a quadratic which is simple to solve:

You can get it to work with Given Find by first dividing through by (0.8SMYS)^2. (Note: you also need to make sigma.h multiply the third term. As originally written it had no multiply sign, so MCAD thought the third term was a function.)
