Purpose & Scientific Principle
This exhibit mainly introduces the knowledge of catenary lines in mathematics. A catenary is a curved line, so named because its shape resembles the shape of a rope suspended at both ends when it falls under the action of uniform gravity. The track of a square wheel car is composed of meshing blocks whose surface shape is an inverted catenary. The degree of arch curvature of the meshing block is determined by the catenary curve. The horizontal size depends on the size of the square wheel, that is, the full length of the inverted catenary is equal to the side length of the square wheel. When the square wheel rolls without sliding on a suitable inverted catenary meshing block track, the undulations of the track offset the changes in the height of the center of gravity caused by the square wheel, and the center of the square wheel always remains at the same height. Therefore, a square wheel rolls almost as smoothly and smoothly as a round wheel rolls along a flat surface.
How to Operate
The exhibition consists of two sets of tracks and trolleys, one is a square wheel trolley and a catenary curve track, and the other is a gear trolley and a gear track. Spectators slide the car and try to make it move. See if the square wheel car can walk on uneven tracks? Compare the driving differences between the two groups of cars?
Operation method: The audience slides the car and tries to make the car move. See if the square wheel car can walk on uneven tracks?
