The team knew the mathematics in nature by watching documentaries, book reading, and online searches. The team tried to make a flexiable “Jingu Bang” as an common telescopic device. The team used Pantograph as the prototype through brainstorm and matrix, and then extended the 6-Bar structure to N-Bar.A prototype of “Jingu Bang” was created. Finally the team did the quantitative analysis on the infinite repeat pattern of the parallelogram. The conclusions were successfully applied to this season.


There is nothing here.

This year,in the VIQC STEM Research Project about "Mathematics in Nature", the 80066B Burning Brain Team chose the topic of making a flexiable “Jingu Bang” based on the infinite repeat pattern of geometric shapes . The team learned about the mathematics in nature through watching documentaries, library research, and online searches, and became very interested in infinite repeat pattern of geometry shapes in nature. At the same time, the team tried to solve the problem of redesigning and validating the retractable device in recent seasons by making a flexiable "Jingu Bang" for future seasons. A brainstorming session was held in the group, and the team decided to use Pantograph as the prototype with the help of the matrix . By extending the 6-Bar mechanical structure to N-Bar, an infinite repeat pattern based on parallelograms was realized, and a prototype of a mechanical Jingu Bang was produced. Then using 14-size Bar as the basic material, the team derived the quantitative relationships between the quantities of bars and the maximum telescopic length . Finally, the conclusions were successfully applied to this VIQC season's extension device, and the team summarized the project in a group presentation.
