From Cooling Towers to the Twisted Tower
★Exhibit Content: Hyperboloid ★Interaction: Electromechanical Interaction ★Operation: Operate different knobs or buttons separately to observe the shape changes of the ruled surface model. ★Exhibit Description: The exhibit mainly consists of an interactive platform, moving discs, elastic ropes, and a driving device. Through changes in the diameter of the upper and lower discs, the exhibit pulls the elastic ropes on the grooves to move continuously. Individually, each elastic rope is a straight line, but when many straight lines combine and rotate, they present various curved surface shapes in front of us, constantly changing, sometimes becoming a thick and sturdy large cylinder, sometimes becoming a shape with thick ends and a thin middle like a slender waist. ★Scientific Principle: A hyperboloid is a surface generated by rotating a hyperbola around its axis of symmetry. A hyperboloid is a type of quadric surface, divided into hyperboloid of one sheet, hyperboloid of two sheets, and hyperboloid of revolution. Hyperboloids not only have a beautiful appearance but also good stability, and are widely used in the construction industry. In reality, the cooling tower structures of many power plants are hyperboloids.
