Flying Butterflies
★Exhibit Content: Rolling friction, principle of gravitational balance ★Interaction: Mechanical interaction ★Operation: 1. Visitors approach the exhibit and read the operation instructions; 2. Turn the handwheel to control the transmission mechanism; 3. Observe the butterfly model rising and descending on the rope to understand the relationship between friction and gravity. ★Exhibit Description: The exhibit consists of a handwheel, transmission mechanism, PU belt, and colorful butterfly models. Visitors turn the handwheel to drive the transmission mechanism, which moves the PU belt, making the butterfly models 'dance' on the rope. When the rolling friction from the wheel exceeds gravity, the butterfly model moves upward along the rope; when friction is less than gravity, the butterfly model slowly descends under gravity, intuitively demonstrating the balance between rolling friction and gravity. ★Scientific Principle: Rolling friction is the force that resists the rolling motion of an object when it rolls, generated at the contact surface. In this exhibit, the transmission mechanism drives the wheel to rotate, and the rolling friction between the wheel, PU belt, and rope acts on the butterfly model. When friction exceeds the model's gravity, it is driven upward; when friction is less than gravity, the model descends under gravity. Through this process, visitors can clearly observe the dynamic balance between friction and gravity, and understand the key role of friction in mechanical transmission.
