Square Wheel Car - Science Museum Exhibits Scheme
What It Shows
Exhibition items allow visitors to experience the magical charm of mathematics by actually operating square wheel carts.
Science Behind It
The curved track of the square wheel car is composed of meshing blocks with a surface shape of inverted catenary lines. The degree of arch bending of the meshing blocks is determined by the catenary curve, and the total length of each arch inverted catenary line is equal to the side length of the square wheel.

Reminder: A catenary is a type of curve, named after its similarity to the shape of a rope hanging at both ends that falls under uniform gravity. When the square wheel performs non sliding rolling on the appropriate inverted catenary meshing block track, the undulations of the track cancel out the changes in the center of gravity height caused by the square wheel, and the center of the square wheel always remains at the same height.
How to Take Part
Ride on an overhead bike and try riding on a curved track.
Description
Exhibition items are set with two square wheeled bicycles of different sizes, allowing visitors to ride smoothly on the curved track without any bumps up or down, source factory of science museum exhibits - Shanghai Inertia Automation Co., Ltd. The reason for this is that the track on which the wheels travel is a carefully designed catenary, and the length of the catenary is exactly equal to the side length of the square wheel. During the driving process, the distance between the center of the wheel and the ground can be kept constant, thus achieving a smooth driving effect.
