You can start and pause the simulation by pressing the Play/Pause button. Pressing the Reset button resets the cylinder positions to the top of the inclined plane.
R outer is the outer radius of the cylinder, you may vary it between 0.05 and 0.3 meter. R inner is the inner radius of the cylinder, it can be varied between 0 and the outer radius.
At inclination angle you can set the angle of the inclined plane. The plane is always 2 meters long, whereas the height is adjusted according to the inclination angle.
The text underneath the I red-label denotes the moment of inertia of the red cilinder, I blue denotes the moment of inertia of the blue one.
The simulation time is displayed underneath the t blue and t red-labels, it stops running when the respective cylinder has reached the end of the slope and touches the horizontal plane.
The simulation stops when the slowest cylinder reaches the end of the inclined plane.
