Apply the Forces

Next, we will apply the nodal forces to the top corner nodes.

1. With the Selection Shape Point or Rectangle and Selection Select Vertices commands active, click the upper-left node of the model.
2. Hold down the Ctrl key and click the upper-right node. Two vertices should now be selected, as shown below.

   

3. Click Setup Loads Force.
   1. Type 5000 in the Magnitude field.
   2. Activate the Z radio button. Each node receives the specified force magnitude, so we have applied a total force of 10,000 lbf.
   3. Click the Flip Direction button ( ) to invert the sign of the Magnitude, reversing the direction of the load. We want the force to act in the -Z direction (downward).
   4. Click OK.
