Stability Model

3D Learning Model: Individual Tracks to Demonstrate Types of EquilibriumThis educational 3D-printed model consists of three separate tracks, each representing a different type of mechanical equilibrium: stable, neutral, and unstable. The tracks are independent of one another and can be placed in any order or used individually during demonstrations.Designed specifically for classroom use, this model is ideal for teaching physics, engineering concepts, or flight theory (e.g., glider pilot training). It allows students to observe and understand how systems react to small disturbances in a direct and tangible way.Each track works with a standard table tennis ball (40 mm diameter) and demonstrates a specific equilibrium behavior:The concave track demonstrates stable equilibrium – the ball returns to its original position after being displaced.The flat track represents neutral equilibrium – the ball remains in its new position without returning or moving further away.The convex track shows u
