Prob. 2.12
Prob. 2.13
2.13 A device for recording ship vibration is shown in the figure. Determine the
natural frequency of the vertical vibration of the weight W, if the moment
of inertia I of this weight along with that of bar BD about the fulcrum B is
known.
2.14 Determine the natural frequency of the cantilever beam of negligible mass
having two weights attached as shown in the figure by Rayleigh’s method.
Prob. 2.14
2.15 Determine the natural frequency in torsion for the shaft carrying two discs as
shown.
