A captive James Bond is strapped to a table beneath a huge pendulum made of a 3.0-m-diameter uniform circular metal blade rigidly attached, at its top edge, to a 5.5-m-long, massless rod. The pendulum is set swinging with a 10∘ amplitude when its lower edge is 3.8 m above the prisoner, then the table slowly starts ascending at 1.0 mm/s.  What is the period of the deadly blade-pendulum? How many oscillations will the deadly blade-pendulum make before it reaches James Bond (provided he doesn't stage a dramatic escape first)?

Forced undamped vibrations

In mechanical engineering, vibration is expressed as the term that occurs due to an object's backward and forward movement about a point of equilibrium. Generally, there are three types of vibrations which are,
