There's definitely some stuff I still don't understand about how all this works. I'm going to type out my thought process from what I have tried so far.
So if I do b.deflection() I can see the deflection equation which has 'x' and 'I' as variables. If I do b.deflection().subs(x,4) that equation simplifies so that only 'I' is variable. do the above as my 'eqn' and do solve(eqn, I) I get an empty list []. But that's probably because it's trying to solve the value of deflection not the value of I. So I need to solve the equation for second_moment If I do b.second_moment() hoping to get an equation I can solve I get the error: 'Symbol' object is not callable Looking through the beam examples pages I didn't see any of solving for anything other than reactions. Would you know of any other pages that have examples of solving in Sympy specifically within the Beam library. -- You received this message because you are subscribed to the Google Groups "sympy" group.
