Webb25 juni 2024 · Double Pendulum. This is a simulation of a double pendulum. For large motions it is a chaotic system, but for small motions it is a simple linear system. You can change parameters in the simulation such as mass, gravity, and length of rods. You can drag the pendulum with your mouse to change the starting position. The small-angle approximation also appears in structural mechanics, especially in stability and bifurcation analyses (mainly of axially-loaded columns ready to undergo buckling). This leads to significant simplifications, though at a cost in accuracy and insight into the true behavior.
