These are the default parameters. Use them in all the assignments if not specified differently:

Most of the results can be checked using the Java simulation!!

Calculate $\omega_+$ and $\omega_-$ (you may use the small angle approximations).
Use $\omega_+$ and $\omega_-$ to calculate the beat and envelope frequency.
Adjust the parameters in such a way that $\omega_+$ is twice as much as $\omega_-$ . You may choose which parameters you change.
Do the same, but now adjust them in such a way that exactly 5 beats fit in 1 envelope.
Derive formula's for $\omega_+$ and $\omega_-$ if we not only set $\alpha_0=R$ but also $\dot \alpha_0=V$ .
The pendula have a lenght, width and a depth. Why is the depth never used in deriving the equations of motion?
Explain what you would expect to happen when the spring is not connected at the same height () for both pendula.
