Hi ! We need help to solve a problem about beams. We would like to use the 'GreenFunction' and we already write this :
Tests GreenFunction
Eyoung = 210000;
d = 20;
Ig = (\[Pi]*d^4)/64;
L = 500;
equ = Eyoung*Ig*w''''[x]
GreenFunction[{equ, w[0] == 0, w[L] == 0}, w[x], {x, 0, L}, x0]
It doesn't work and we don't know why. We used the "help" of Mathematica but we can't solve the problem.
Thanks for your answers. C.
