I am dealing with a problem in engineering mechanics, but my when using maple to solve the governing nonlinear equation with 4 bcs, I meet with error. 

Error, (in dsolve/numeric/bvp) initial Newton iteration is not converging

my code is :

deq := diff(y(x), `$`(x, 4)) = -.364*(diff(y(x), x))^2*(diff(y(x), `$`(x, 2)))+1.74*10^(-7)

bc := y(0) = 0, (D(y...
