Vector Mechanics for Engineers: Statics and Dynamics
A collar with mass $m$ that slides on a frictionless horizontal rod is attached to a spring with constant $k$ and is acted upon by a periodic force with a magnitude of $P=P_{m} \sin \omega_{f} t .$ Determine the range of values of $\omega_{f}$ for which the amplitude of the vibration exceeds three times the static deflection caused by a constant force with a magnitude of $P_{m}$.
