Using the program CHOLJAC, solve for the eigenvalues and eigenvectors for the 4 X 4 beam in Example 10.5-1.
Example 10.5-1
The beam in Fig. 10.5-1 is considered as two equal elements of length l/2, whose stiffness and mass matrices are given by Eqs. (10.2-1) and (10.2-10). With l/2 substituted for I, the element matrices are as folIows:
