Why in a tug of war, whichever side has more friction wins?

The action of the force is mutual, and the pulling force received by both parties is equal, while the opposite of this force is the frictional force.

If the friction is greater than the pulling force, the side will retreat and win.

According to Newton's third law.

That is, when object A gives object B one.

A force is applied to object B at the same time.

The action and reaction forces are equal in magnitude, opposite in direction, and in the same straight line).

For the two teams in the tug-of-war, how much pull A exerts on B, B also produces the same amount of pull on A at the same time. It can be seen that the pull between the two sides is not the factor that determines the victory or defeat.

A force analysis of the two teams in the tug-of-war shows that as long as the tensile force is less than the maximum static friction with the ground, it will not be pulled. Therefore, increasing the friction with the ground becomes the key to victory or defeat.

First of all, wear shoes with a concave and embossed soles to increase the coefficient of friction.

increase friction; In addition, the heavier the weight of the players, the greater the pressure on the ground, and the greater the friction. When it comes to tug-of-war between adults and children, adults easily win, and the key is that adults weigh more than children.

Also, in the tug-of-war competition.

Victory or defeat also depends largely on people's skills. For example, if you push the ground, you can put more pressure on the ground than you think on in a short period of time. Another example is when a person leans back, using the other party's pull to increase the pressure on the ground, and so on.

The aim is to maximize the friction on the ground against the soles of the feet.

The balance of the two forces is the same, so the friction wins.

The force acts on each other, the force on both sides of the rope is equal, and if there is no friction, there is no victory or defeat.

Both parties are in the same straight line, and in order to pull each other, you have to pull more on the other than the friction on the other side.

If there is a lot of friction, it is not easy to be pulled by the other party.

If the friction is high, the pulling force will be great.

The greater the friction, the greater the resistance.

The action of force is reciprocal.

The rope deformation is equal everywhere.

Tug-of-war is a powerful sport that maximizes the potential of athletes on the field and has a high viewing value. In the preparation stage of this sports meeting, Bian Xiao carefully collected the relevant techniques of tug-of-war and submitted them here.

The focus of tug-of-war is not the amount of tension, but the amount of friction between people on both sides of the ground. So, looking at the tug-of-war, the people with more fat people win more. This is not only because they are strong, but also because they are heavy.

According to the friction calculation formula, the greater the pressure on the plane, the greater the friction! Tug-of-war is easy to win.

In tug-of-war, whoever gets more friction from the ground wins. Friction is related to the pressure on the ground, the roughness of the contact surface between the feet and the ground. Therefore, in order to win, it is necessary to first choose a player with a larger weight to participate, which plays a role in increasing gravity, increasing ground pressure, and increasing friction on people.

Moreover, wearing sneakers with rough bottoms will increase the roughness of the contact surface and increase friction.

However, if the correct tug-of-war posture is adopted, the friction will increase even further.

The correct posture is to lean back, so that the angle between the body and the horizontal plane is less than 45 degrees, reduce the center of gravity to improve stability, and increase the pressure on the ground. Athletes are used as stress targets to analyze stress conditions. In tug-of-war, athletes are affected by three forces: tension, gravity, and friction.

Friction is the winning force, as the body leans backwards, the pull and gravity combine into one force, the pressure on the ground increases, and the friction increases.

When adopting an upright or semi-squatting position, vertical tension and gravity do not increase the pressure on the ground, and the body leans forward due to tension and friction, which is prone to malfunction. So this posture is not advisable.

As long as you master the skills of tug-of-war, you can win with strength.

In the tug-of-war competition, the position is very important, the light weight person stands in front of the heavy person behind the back, the body inclination should reach more than 45 degrees during the tug-of-war, and finally there is the question of rhythm. One person should be asked to shout 123 and then force together.

I think that in a tug-of-war competition, the feet of each player are separated by a certain distance, and their feet are on top of each other, and they lean back when they exert force, so that the maximum effect can be played.

I think it's to gradually press the rope to the lowest level, and everyone leans back collectively. will exert the maximum force.

At the beginning of the game, feel the size and rhythm of the opponent's force, and at the same time exert the force to balance it, when the opponent is in the gap between the two forces, seize the opportunity, quickly exert force, and make a big move, at this time the force exerted can only be larger and larger, not reduced.

Everyone listens to the slogan, leans back, pulls back together, stands with their feet crossed, and everyone has the confidence to win.

Surely, whichever side has the most strength will win.

2 times together, everyone's center of gravity presses down.

To wear shoes with a lot of friction, the tug-of-war people are arranged on one left and one right to keep the rope balanced. Before starting, you should use some force on the rope, and when the whistle is blown, it is best to have a person standing next to you to lead the rhythm, and the people in the tug-of-war shout the slogan "while pulling" to ensure that there is a rhythm of force. When these things are done, there will be a better chance of victory than the other person.

Tug-of-war skills

The first is the standing position of the personnel. The small man in front and the big man in the back cross positions in a T-step order. The front leg is 120-130 degrees, the back leg is 90-110 degrees, and the distance between the two feet is slightly greater than the shoulder, which can not only save space, but also ensure that the collective force acts on the rope in a straight line.

It's best to wear shoes with embossed soles to compete to bring out the best in everyone.

The second is the grip. A good grip is the best way to win. The traditional grip is to hold the rope with both hands, two points and one line, and connect the front and back.

But there is one to do so"Fatal", the interval between the front and rear two people is dismantled, and the elongated jujube battle line is not easy to control the straight line force, and in the evenly matched competition, a little mistake will lead to "tail swinging", and even lose the whole game.

To three points and one line, both hands plus the "back" armpit, tightly clamp the rope, in addition, the back of the team members from the armpit into the front of the two hands of the middle position to hold the rope, in this way, the team's battle line is short, the effect of the straight line acting on the rope is obvious, even in the case of teammates mistakes can also ensure timely adjustment.

The third is rhythm. Speed up the rhythm of the attack, use one-half of the beat, adopt the quick combat method of 1 force pure and 2 stuffy, do not give an inch, press step by step, break the opponent's rib rhythm and overall tactics, put pressure on the opponent, and achieve the effect of surprising victory.

Finally, seize the moment. At the beginning of the game, it is necessary to stabilize the rope in advance, and the leader of the platoon is under unified command, at this time, you must not be careless, and try to prevent the opponent from exerting force in advance, so as to prevent you from being caught off guard and failing in a daze.

In the tug-of-war competition, the two parties are A and B, and first of all, it should be clarified that the pull force of A to B and the pull force of B to A are the action force and the reaction force, and the action force and reaction force have nothing to do with the state of motion. These two forces, one is the force of A to B, B is the force object, and A is the force object, which is expressed as f A to B; The other is the force of B against A, A is the object of force and B is the object of force, which is expressed as f B to A. f A to B and f B to A are in a straight line, in opposite directions, and these two forces are action and reaction.

It can be seen that in the tug-of-war between teams A and B, the force of team A against team B and the force of team B against team A are a pair of action and reaction forces, and their magnitude is equal.

Secondly, the movement of the teams depends on the maximum static friction experienced by the teams. Assuming that the ground is level, the rope in the tug-of-war is also horizontal, and Team B is pulled because the force of Team A against Team B is greater than the maximum static friction experienced by Team B. So if you want to win in a tug-of-war, finding a way to increase the maximum static friction is the key.

Tug-of-war is a rally competition in which two people or groups of people pull against each other, and in the end, whoever gets the rally to reach the breaking point first wins. There are two sides participating in the tug-of-war, one is the team that pulls the team, and the other is the team that blocks the team. The two teams pull each other apart, and in the end, whichever team can pull the other team to the breaking point wins.

In a tug-of-war, the key to success lies in the balance of power between the two sides of the tug-of-war. The two sides of the tug-of-war should exert force at the same time when pulling, but the degree of force should be mastered within a certain range, otherwise there will be an imbalance in the strength of pulling, when the strength of one side is greater than the strength of the other side, it will make the pull of the other side reach the breaking point and win.

In addition, the part of the puller in the tug-of-war is also very important, generally speaking, the two sides should try to be consistent in the part of the pull, so that the strength of the two teams is as balanced as possible, so that the two sides can better play the puller game and win.

All in all, the key to winning the tug-of-war lies in the balance of power of both sides, the reasonableness of the pulling point, and the degree of force of both sides in the tug-of-war.

Then one of the most important reasons to win a race is weight and strength. We have all participated in tug-of-war competitions organized by schools or units.

So when we select the personnel for the tug-of-war competition, we must always choose some comrades who are strong or look a little larger to participate. It's never about picking some skinny people or people who look weak to participate, so we all know that tug-of-war is won by strength. <>

But despite this, it's not just the big or the big guys who can win the gameThe most important thing is also the people who shout slogans and the strategy. For example, our unit was halfway through the game some time ago, and in the tug-of-war competition, one team pulled three units in a row and won the final victory. In addition to selecting many young adults to participate, they also sent a teacher with a voice shouting slogans and regular teachers to shout at them.

Like tug-of-war, it can't be said that as soon as the factory is opened, it will be pulled back, but it must be loosened and tightened regularlyBut Song didn't mean to send the rope to the other side and let the other side take it, but to keep it still and pull it back as much as possible when the strength was there, so the person who shouted was very important, and he would directly determine whether everyone's strength was at the same point in time, so if it was scattered, he would never be able to pull the other party over, but everyone needed to use their strength at the same point in time, so as to win with one move. <>

In addition, the position is also very important, generally speaking, the first person should choose the larger of the questionsBecause the first person should be stable and not cross the line, once they meet, it is easy to be pulled by the other party, and the last person should also choose a larger weight. The last place is equivalent to a "scale", to stabilize the whole team at the origin, and the middle person to occupy the place to stagger the hands and feet, everyone to integrate their strength together, so that in the Ba River can pull the other party across the line in the fastest way.

The key to winning in the tug-of-war competition is weight, because tug-of-war is to put it bluntly, it is to compare the weight of both sides, and the side with the greater weight has a big advantage, and the other party wants to pull you over, so you need to pay the same strength as your weight to be able to pull, so the key to winning is weight.

The weight of all team members, from the point of view of physics, the traction force needs to be greater than the maximum static friction force to produce movement, and the maximum static friction force depends on the weight of the participating players in the game, as long as the overall weight of the team members is large enough, the chance of losing is smaller.

In the tug-of-war, the last person must choose the one with more strength and heavier weight to have a chance of winning.
