Thin, homogeneous bars OA and AB each have a mass of m and length L. OA is pinned
to ground at A, and the two bars are pinned together at A, as shown in the figure below.
Rotational springs (each of stiffness K) connect OA to ground and OA to AB at pins O
and A, respectively. (See Appendix VI of...
