Apply the Forces in the -X Direction

Now we apply the four 175 lbf forces in the -X direction to the center of the model.

1. Click and drag to draw a box enclosing the center of the model as shown in the following image.  
   
2. Click Setup Loads Force.
   1. Type -87.5 in the Magnitude field
   2. Select the X radio button. Again, we have cut the force in half because there are two nodes at each vertex, one per part.
3. Type 2 in the Load Case / Load Curve field and click Curve. The Multiplier Table Editor dialog box displays for defining a load curve.
   1. Click Add Row three times so that there is a total of four rows in the table.
      • Type 2 in the second row of the Time column.
      • Type 2.25 in the third row of the Time column
      • Type 1 in the third row of the Multiplier column.
      • Type 4 in the fourth row of the Time column.
      • Type 1 in the fourth row of the Multiplier column.
   2. Press Enter. The load curve should appear within the dialog as shown below.
