<p>A bending beam is fixed on the left side with a corresponding force on
the right side. All nodes on the left side of the model are fixed in the x-axis
direction. The node on the lower-left side is also fixed in the y-axis
direction. A force of 40N is applied on the right side in a positive direction
of the y-axis.
