Hyperbolic Slot
★Exhibit Content: Hyperboloid ★Interaction: Mechanical Interaction ★Operation: Press the start button and see what happens. ★Exhibit Description: The exhibit consists of a display stand, a rotating motor, a rotatable straight rod, and an acrylic plate with a hyperbolic slot. Press the start button, and you will find that it can magically pass through the curved slot on the acrylic plate. ★Scientific Principle: What is the mystery behind this? When the inclined straight rod rotates around the vertical axis, it traces a hyperboloid in space. Since the acrylic plate is a plane passing through the vertical axis, the curved slot is exactly the intersection line of the acrylic plate and the hyperboloid. When the straight rod rotates, it passes exactly through the curved slot. The cooling tower structure of a thermal power plant is a hyperboloid shape, which can be constructed with straight steel beams. This reduces wind resistance and also maintains structural integrity with the least amount of material.
