(e) Eigenvalue Buckling Part

 The eigenvalue buckling analysis can be now performed.
The data from the static structural analysis (model, mesh,
solution, etc.) can be transferred directly to the buckling
analysis.
 Drag the Eigenvalue Buckling icon from the Analysis
Systems Toolbox window and drop it on to the Solution
cell of the highlighted Static Structural in the Project
Schematic window.
 Retype the name in the lower blue tab as the desired project
name, e.g., Eigenvalue Buckling, and hit Enter.

 Double click on Setup under Eigenvalue Buckling, a new
window of Multiple System appears. Right click on
Solution under Eigenvalue Buckling and select Solve, the
buckling analysis is now performed.
 Click on Solution and select Total Deformation under
Deformation tab. Right click on Total Deformation and
select Evaluate All results, the fundamental mode shape
will appear as shown in the figure with the computed Load
Multiplier of 6727.2.
 Because the input force P is 1 N, this means the critical load
is 6727.2 N.
