Coupled Pendula with Cobra3
Principle: Two equal gravity pendula with a particular characteristic frequency are coupled by a "soft" spiral spring. The amplitudes of both pendula are recorded as a function of time for various vibrational modes and different coupling factors using a y/t recorder. The coupling factors are determined by different methods.
Tasks:
1. To determine the spring constant of the coupling spring.
2. To determine and to adjust the characteristic frequencies of the uncoupled pendula.
3. To determine the coupling factors for various coupling-lengths using
a) the apparatus constants
b) the angular frequencies for "inphase" and "in opposite phase" vibration
c) the angular frequencies of the beat mode.
4. To check the linear relation between the square of the couplinglengths and
a) the particular frequencies of the beat mode
b) the square of the frequency for "in opposite phase" vibration.
5. To determine the pendulum's characteristic frequency from the vibrational modes with coupling and to compare this with the characteristic frequency of the uncoupled pendula.
