Sample Vibrations Problems Solved Part 3

In this video, 3 vibrations problems with solutions are provided: Free vibrations of a 2DOF system (double pendulum with small angles) and finding the natural frequencies, mode shapes and node locations; Rayleigh's method for estimation the fundamental frequency of a beam with weights on it, and Free vibrations of a continuous system (a torsional shaft with a fixed end and a torsional spring on the other end).
