Unsolvable Solver Section That Needs a Solve
I've avoided solvers since the begining. I never can get them to behave how I want. My most recent attemp to try and get over this self inflicted restriction (because solvers would be super useful) is shown below in a snapshot.. Any idea why it's not solving? U_max should be ~0.97 or something but even when I put in an initial guess it can't figure it out.
HELP!!!!!
Text output for anyone trying to re-create it:
R_u=30 kip
Φ=1
F_y=46 ksi
t=0.465 in
t_p=0.5 in
B=10 in
l_b=2 in*2+3 in*2 = 10 in
R_u=ΦR_n
ΦR_n=Φ*(F_y*t^2/(1-t_p/B))*(2*l_b/B+4*Sqrt(1-t_p/B)*Q_f)
Q_f=Sqrt(1-U_max^2)
