Driven pendulum (forced oscillation)

Original project Driven pendulum (forced oscillation)

There are three springs all driven by external force with different frequency.
The resonance frequency is determined by $\omega_0=\sqrt{k/m}$ where k is the spring constant, m is the mass (k,m can be adjusted with slider).
When sync check box is checked:
The driven frequency for left spring is $ratio*w_0$ ,
The driven frequency for center spring is $w_0$ ,
The driven frequency for right spring is $ratio/w_0$ .

You can find the phase between oscillation and external force.
A damping force is introduced to prevent the amplitude become infinity.
