Orthogonal Cross Mill
★Exhibit Content: Cardan Ellipsograph ★Interaction: Mechanical Interaction ★Operation: Read the instruction board to understand the working principle of the Cardan ellipsograph; push the operating lever to observe the motion trajectories of the two sliding points and the moving rod. ★Exhibit Description: This exhibit consists of a display stand, a mechanical interactive device, and graphic instructions. The main body of the exhibit is a model of an ellipsograph. By moving the handle along an elliptical trajectory on the exhibit plane, the working principle of the Cardan ellipsograph is demonstrated. Push the grinding disc while keeping the handle position fixed, and the trajectory traced around the grinding disc is an ellipse. Visitors can hold the handle and move it within the permitted range of the ellipsograph to verify whether the motion trajectory coincides with an ellipse. ★Scientific Principle: By moving the handle along an elliptical trajectory on the exhibit plane, the working principle of the Cardan ellipsograph is demonstrated—a person pushes the grinding disc while keeping the handle position fixed, and the trajectory traced around the grinding disc is an ellipse. This exhibit shows visitors the basic principle of the ellipsograph. The trajectories of two points fixed on a lever intersect at right angles. A movable slider is mounted on a cross-shaped slide groove. Below the slider is a rotating rod. This rotating rod is connected to both the longitudinal and transverse sliders as one unit. Participants push the slider and move it accordingly; the two sliders in the track move smoothly without colliding, the two sliders move in two slots, and the trajectory of each point on the moving rod is an ellipse with different major and minor axes.
