Plotting eigenvectors corresponding to zero eigenvectors for a 3 bar truss system
Assume the following case of a 3 bar truss system:



Where a=b=1, and the three bar properties consist of; E=2 and A=3. This means for all elements, $$\ k=\frac{(EA)}{L}=\frac{(2*3)}{1}=6 $$

The system can be described as $$\ \mathbf{K} * \mathbf{v}= \mathbf{\lambda\ }* \mathbf{v} $$

Where $$\ \mathbf{K} $$ is the 6x6 stiffness matrix for the contrained system.
