### MAGIC RAMIE ROPE FOR THE TUG-OF-WAR GAME

**ABSTRACT**

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.
