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. WebbBernoulli-Euler Assumptions. The two primary assumptions made by the Bernoulli-Euler beam theory are that 'plane sections remain plane' and that deformed beam angles (slopes) are small. The plane sections remain plane assumption is illustrated in Figure 5.1. It assumes that any section of a beam (i.e. a cut through the beam at some point along ...
