Rocking Semicircular Hoop Model Description

Shows the dynamics of an object rocking without slipping on an horizontal surface Rocking Semicircular Hoop Model is a free program that shows the dynamics of a simple object rocking without slipping on a horizontal surface. The object, a semicircular hoop with radius R, is acted on by gravitational, frictional, and normal forces. Although the system executes simple harmonic motion at small angles, its large angle oscillations are nonlinear. The angular acceleration for the semicircular hoop can be derived through Lagrangian dynamics or by computing the torque about the point of contact. The paper by Turner and Turner derives the equation of motion from an analysis of the torque and the Rocking Semicircular Hoop model displays the numerical solution and shows how the forces and torques evolve in time.
