This is a simulation of a circular object mounted on an axis through its center with a constant torque applied. Objects with varying rotational inertia (solid sphere, spherical shell, solid cylinder, cylindrical shell) can be chosen, and the mass and radius of the object can be adjusted.
Use the checkboxes to select the type of circular object. Use the sliders to adjust the radius and mass of the circular object, as well as the amount of force applied at the object's rim. Press the Start button to begin the animation. Soon the amount of torque acting and the object's angular acceleration will be shown. Press the Reset button to reset the animation.
