摘要

拔河是一项以实力著称的运动，但实力较弱的队伍也可以通过适当的团队合作赢得比赛。建立了一个数学模型，表明团队合作或节奏频率对胜利起着重要作用。根据节奏的不同，即使绳子被拉向相反的方向，也有可能获胜。为了保证两队在实力基本相同的情况下获胜，给出了节奏频率的判定标准。此外，绳子也可以用来移动重物，这个原理可能被用于建造古埃及的大金字塔。最后讨论了具有特殊热塑性性能和可控频率的神奇苎麻绳。

Magic ramie rope for the tug-of-war game

The tug of war is a sport known for strength, however a weaker team can also win the game by a suitable team co-operation. A mathematical model is established, showing that the team co-operation or rhythmical frequency plays an important role in victory. A team can win even the rope is pulled to the opposite direction depending upon the rhythmical frequency. A criterion for rhythmical frequency is obtain to guarantee victory when the strength is almost same for both teams. Additionally the rope pulling can be also used for moving a heavy weight object, the principle might be used for building the great pyramids in ancient Egypt. Finally magic ramie ropes with special thermoplastic properties and controllable frequency are discussed.

期刊介绍： The main aims of Thermal Science to publish papers giving results of the fundamental and applied research in different, but closely connected fields: fluid mechanics (mainly turbulent flows), heat transfer, mass transfer, combustion and chemical processes in single, and specifically in multi-phase and multi-component flows in high-temperature chemically reacting flows processes present in thermal engineering, energy generating or consuming equipment, process and chemical engineering equipment and devices, ecological engineering, The important characteristic of the journal is the orientation to the fundamental results of the investigations of different physical and chemical processes, always jointly present in real conditions, and their mutual influence. To publish papers written by experts from different fields: mechanical engineering, chemical engineering, fluid dynamics, thermodynamics and related fields. To inform international scientific community about the recent, and most prominent fundamental results achieved in the South-East European region, and particularly in Serbia, and - vice versa - to inform the scientific community from South-East European Region about recent fundamental and applied scientific achievements in developed countries, serving as a basis for technology development. To achieve international standards of the published papers, by the engagement of experts from different countries in the International Advisory board.
