Results
Plot the result for radial displacement variation with applied load at
points A and B.
Process the results of the analysis using graphing software to
generate the graph.
The Y-axis shows
displacements
in inches and the X-axis
shows
the applied load P in pounds. The blue line shows the radial displacement
at point A and the red line shows the radial displacement at point B.
The force-deflection curves agree with the finite element solution provided
in the reference.
