The direction of the grain of the way is in y-axis, because when cutting the piece of wood, they do it radially, so that the force is generated perpendicular to the fiber. 


 With regard to that I wanted to ask you one thing, how the direction of the wood is on the shaft and, it is expected that this is the one that handles the Young module with the most value, I wanted to change those parameters by reversing the values in the properties of the materials, but it does not seem to be allowed to use a value on the y-axis (of the Young module) greater than the x-axis. Do you know how if there is any way to solve that?
