Apply the Forces

Next, we apply downward nodal forces to the vertices around the edge of the hole in the horizontal part.

1. Click inside the hole in the horizontal part, near its edge, to select the surface.
2. Right-click and choose Select Related Vertices. All of the nodes belonging to the previously selected surface are now selected, as shown below.

   

3. Click Setup Loads Force. Notice that the title bar of the dialog indicates the number of selected nodes.
   1. Type 2500/24= in the Magnitude field. This field now shows the total force divided by the number of selected nodes (=104.167), which is necessary because the specified magnitude is the load applied to each individual node.
   2. Activate the Z radio button.
   3. Click the Flip Direction button ( ), negating the sign of the Magnitude value. We are making the force negative because we want it to act in the -Z (downward) direction.
   4. Click OK.   

   The model displays as shown in following image.
