I read an article that the author simulated this problem statically:

In the shaft has been radius all 0.003 m in size. He consider AISI 1050 steel with Young's elasticity modulus of 206.8 GPa and Poisson modulus of 0.28, Suit = 690 Mpa, S = 580 Mpa.

So he did it:

And your result was:

I know his results is correct, obviously, but when I try to do the same thing:

Results:

Am I using the correct displacement?
