The ropes of tug-of-war

Tug-of-war is a popular sport which many people can play together irrespective of when and where they play or who they play with. It is also a good full-body workout, especially for arms and legs.

However, it is quite wrong to think of it as a contestof strength.

According to Newton’s third law of motion, when a force acts on a body due to another body then an equal and opposite force acts simultaneously on that body. Therefore, if the two teams have the same weight and keep a firm grip on the rope and the friction resistance is zero, one team can drag the other by pulling the rope by a certain distance.

This means that not being pulled is more important than pulling in a tug-of-war game.

In order to win, first of all, you should make sure that the rope does not slip off your grip and, therefore, you should hold it tight and make your hands less slippery.

And then the friction resistance of the floor should be as strong as possible.

So you should wear special shoes whose material and structure are designed to have great friction resistance.

It is also important to maximize the downward pressure of shoe soles.

Actually, the pressure applied to the floor in a game can be increased with several tricks besides the increment of body weight.

For example, if you tread heavily on the floor with both feet, the pressure on the floor can be more than the downward force given by your body.

And you can induce the pulling force of the opponent to increase the pressure on the floor by bending your upper body backward.

Thus, a tug-of-war game is a match of not just strength but intelligence and a contest of science and technology.
