Rolling Out Patterns
★Exhibit Content: Tangent, Hypocycloid ★Interaction: Electromechanical Interaction ★Operation: Press the "Start" button and observe the movement trajectory of the small animal model. ★Exhibit Description: The exhibit mainly consists of a display stand, three sets of demonstration models and small animal models, etc. In each set, the fixed large circle is the same, and the diameters of the small discs that can perform internal tangent motion with the large circle are 1/2, 1/5, and 1/8 of the large disc diameter respectively, and an animal model is fixed at any point on the edge of the small disc. ★Scientific Principle: In geometry, a tangent line is a straight line that just touches a point on a curve. More precisely, when a tangent line passes through a certain point on a curve (i.e., the point of tangency), the direction of the tangent line is the same as the direction of the curve at that point. In plane geometry, a line that has only one common intersection point with a circle is called a tangent to the circle.
