Bead on a Rotating Hoop
Requires a Wolfram Notebook System
Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.
This Demonstration uses Lagrangian mechanics to simulate a system in which a bead is free to slide along a frictionless hoop. The plane of the hoop is horizontal, and its center travels on a horizontal circle about a given point with constant angular velocity.
