Displacement of taut string simulation. Resonance in a Driven String model displays the displacement of taut string with its right end fixed while the left end is driven sinusoidally. The driving frequency, amplitude, and the simulation's dt can be changed via text boxes and the motion can be further fine tuned by zooming in and out with the slider provided. You can modify this simulation if you have Ejs installed by right-clicking within the plot and selecting "Open Ejs Model" from the pop-up menu item.

Ejs Resonance in a Driven String model was created using the Easy Java Simulations (Ejs) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_ehu_waves_resonance.jar file will run the program if Java is installed. Ejs is a part of the Open Source Physics Project and is designed to make it easier to access, modify, and generate computer models. Additional Ejs models for wave motion are available. They can be found by searching ComPADRE for Open Source Physics, OSP, or Ejs.

The simulation computes the steady state solution and can be used to check how resonance happens when the driving frequancy is (nearly) one of the normal frequencies, i.e. , one of the frequencies of the standing waves that may appear in the string when both ends are fixed.
The unit length is L and the unit time L/v, where v = v(TL/m) is the phase velocity of transverse waves propagating along the string, whete the tension is T.
You can select below the dimensionless frequency of the driving force, ? = O L/p v, and its amplitude A, as well as the number of discretization points N and the time interval between animation frames.
