Coupled Pendulum Oscillations SK067

 

Exp-1 Study the characteristic frequencies of the uncoupled pendulum.
Exp-2 To determine the coupling factors for various coupling lengths, the angular frequencies or "in-phase" and "in opposite phase" vibration, and the angular frequencies of the beat mode.
Exp-3 To study the linear relation between the square of the coupling lengths, beat mode, and the square of the frequency for "in-opposite phase" vibration.
Exp-4 To determine the spring constant of the coupling spring.

Coupled Pendulum

Two equal length pendulums with same mass have a particular characteristic frequency are coupled by a spiral spring. The amplitudes of both pendulums are recorded as a function of time for various vibrational modes and different coupling factors using a motion detector. The setup can be used to study “in-phase”, “in-opposite phase”, and “beat” mode.
