Mechanical Pendulums vs DR.Osci.HD

In mechanics, in the area of dynamical system, a N-tuple pendulum is a set of N simple pendulums attached to each other. These N-tuple pendulums are physical systems that exibits rich dynamical behavior. For certain energies, are the motion of these mechanical pendulums often chaotic. You can influence the motion of the pendulums by holding your device in different positions. The equations of motions of these pendulums has been derived using the Sophia mechanical package. The different set of differential equations are solved using the 4:th order Runge-Kutta method for the time stepping. Within this application you can switch between these mechanical pendulums: - Double - Triple - Quadruple - Quintuple - Sextuple - Octuple - Symmtric Double - Simple 3-Dimensional The visualization of the pendulums can be viewed in either a Quartz view or in an OpenGL view.

In this simulation of a spring pendulum a mass is attached to two springs. You can touch the mass and move it out of its stable position. Or you can tilt your iOS device and watch gravity work. At all times you can alter the damping (k), the flexibility of the spring (D) and the mass of the steel ball (m). Take some time and play around with these parameters to become an expert in harmonic and not so harmonic oscillations. If you have found an interesting one, tap the graph button to record the displacement over the time. Tap the info button to enable or disable gravity and to export graphs into your photo library.
