Is it possible to move the earth with a lever?

Theoretically, yes, but it's too hard.

I'll give you a copy of it for you to see.

Give me a fulcrum, and I'll pry up the earth! According to legend, this is the words of Archimedes, who discovered the principle of levers in ancient times. Archimedes knew that if he used a lever, he could lift anything heavy with a minimum force, just by putting that force on the long arm of the lever and letting the short arm act on the weight.

However, if this great ancient scientist had known how massive the earth was, he might not have boasted about it like that. Let's imagine that Archimedes really found another earth to serve as a fulcrum; Imagine that he has made a lever long enough. Do you know how long it takes him to lift a weight equal to the mass of the Earth, even if it is only 1 cm?

At least 30 trillion years!

Earth's mass astronomers know that if it were to be weighed on Earth, it would weigh about 6 000 000 000 000 000 000 000 000 000 tons.

If a person can only lift a weight of 60 kg directly, then in order to "lift the earth", he has to put his hand on a lever of this length, and his long arm should be equal to 100 000 000 000 000 000 000 times his short arm!

A simple calculation shows that if you raise the end of the short arm 1 cm high, you have to draw a large arc in the universe with the end of the long arm, and the length of the arc is about 1 000 000 000 000 000 000 km.

This means that if Archimedes were to lift the earth by 1 cm, his lever-holding hand would have to move such an unimaginable distance! So how much time will it take him to get this done? If we consider that Archimedes can lift a 60kg weight by a meter in a second (this is almost equal to one horsepower!). Then, if he wants to lift the earth by 1cm, it will take 100 000 000 000 000 000 000 000 000s, or 30 trillion years! It can be seen that Archimedes could not complete this task.

According to Newton's second law ... You tap it in the universe and it will move ... You can use it with or without leverage.

Theoretically, but not in practice, because there is no fulcrum and a lever that is large enough!

It's Euclid's principle of leverage, as long as you have a fulcrum and a long enough distance.

The ancient Greek scientist Archimedes famously said, "Give me a fulcrum, and I can pry up the whole earth!" There is a strict scientific basis for this statement.

F1L1=F2L2 And the earth's F1L1 is constant, the problem now is that the human force is much less than the earth's gravity, so when the larger L2 is used, that is, the increasing force arm can reduce F2 that is, F1L1=F2L2 F1L1 is constant, and the increase L2 F2 decreases. In the process of increasing L2, there is always a moment when F2 is within the power of man. So the earth can be moved.

But in reality, this fulcrum is just an ideal model, which does not exist in reality. So, if you can find such a fulcrum, you can move the earth.

Yes, Archimedes said, the principle of leverage.

Actually, no, not (although theoretically).

This is unrealistic and can only be held up theoretically.

How is the mass of the Earth measured? Giving you a lever, can you really pry the earth?

The first person to discover the principle of the lever was Archimedes of ancient Greece. The discovery of the principle of lever formed the basis for the development of machinery. To a large extent, it liberated the labor force and laid the foundation for the development of material society.

Archimedes' research on lever meditation was not only theoretical, but also led to a series of inventions. In the battle to defend Syracuse from the Roman navy, Archimedes used the principle of levers to create long-range and close-range catapults, which were used to shoot various missiles and boulders to attack the enemy.

There have also been records of leverage in Chinese history. Mozi of the Warring States Period once proposed that there are two special records of the principle of leverage in the Book of Ink.

Archimedes is most widely known as: "If you give me a fulcrum, I can pry the earth!" Of course, such a fulcrum and lever cannot be found, but theoretically, if any, Archimedes is the number of rubber attacks that can pry the earth.

Theoretically, these words are very likable, it is very magical, and many ideas that are difficult to realize will bring people an illusory truth. Theories often have to be combined with practice, and they are the fulcrum for the implementation of ideas. The emergence of any problem is the product of the combination of ideology and environment, and in dealing with problems, the ideological environment should be grasped with both hands, and conclusions should be drawn after analyzing the environment and specific problems.

The textbook knowledge we learn only gives us theory, practice produces true knowledge, and learning from things.

Not nonsense.

After discovering the principle of the lever, Archimedes exclaimed, "Give me a fulcrum, and I can pry the earth."

Archimedes' emotion is nothing more than a theoretical emotion.

The principle of the lever is: power arm power = resistance arm resistance.

The power here is the force that man (i.e., Archimedes) can exert himself; Resistance is the mass of the Earth.

According to the principle of leverage, it can be obtained: power = (resistance arm power arm) resistance.

Suppose the force that Archimedes can exert is 100 kilograms, and the mass of the earth is 6 10 24 kilograms. Substituting the above formula, there are:

100 = (resistance arm, power arm) 6 10 24

Power Arm Resistance Arm = 6 10 22

Power arm = 6 10 22 resistance arm.

It can be seen that as long as we can find a lever that is long enough and find a fulcrum so that the length of the power arm is 60 trillion times the length of the resistance arm, Archimedes can pry the earth!

But even if such a lever and fulcrum can be found, Archimedes can support it to the earth and the fulcrum, and can go to the other end of the lever, and the weight of this lever is 0.

If Archimedes wants to pry the earth by 1 millimeter, Archimedes has to push the lever to travel 6 quadrillion kilometers, which is more than 40 million times the distance from the earth to the sun!

Hope it solves your problem.

How is the mass of the Earth measured? Giving you a lever, can you really pry the earth?

Aki did say this, the Leaning Tower of Pizza is also true, Newton was smashed to discover that the earth's gravity really had little effect, and Newton only used his previous life to engage in physics, and the rest of his life was engaged in finance, there are indeed problems with Chinese textbooks, and I don't want to say much about national conditions, the earth should be the meaning of the world at that time.

"Give me a fulcrum, and I will pry the earth. This famous quote of the ancient Greek mathematician Archimedes is still recited today.

For thousands of years, "Give me a fulcrum, and I will move the earth." The meaning of this sentence has long gone beyond the initial context of what Archimedes said, and has been attached to more philosophy of life and other aspects of humanistic and social implications by later generations. If it is clear and unambiguous that Archimedes used this sentence to express the great power of the principle of leverage and mathematical logic, then it is difficult to grasp the connotation of this sentence after it has been added to the meaning of humanities and social sciences beyond the mathematical world.

Do you want to express that "I" can do anything, even the earth can be moved, or do you want to convey a kind of helplessness and confusion that cannot find a fulcrum? As a symbolic or figurative body, what is the "fulcrum"? What is the "earth" to be leveraged?

In different linguistic contexts and expressions, the implication of these two points is also multimillion.

It is a practical problem illustrated by the principle of leverage: when we have certain conditions, we can do many seemingly impossible things. For example, it's hard to imagine that we can pry the earth, but when we have a fulcrum, it's not a problem.

According to scientists' calculations, the lever that moves the Earth needs to extend beyond the Milky Way!

Yes, but not such a long leverage.

Principle of Leverage Balance: The main focus is to highlight the impact of leverage on balance. However, I personally think that this sentence has the meaning of "everything is possible".

The principle of leverage is also known as the "leverage equilibrium condition". For a lever to be balanced, the magnitude of the two forces acting on the lever (the force point, the fulcrum, and the resistance point) is inversely proportional to their force arms. Power Power Arm = Resistance Resistance arm, expressed algebraically as f1· l1 = f2·l2.

where F1 represents the power, L1 represents the power arm, F2 represents the resistance, and L2 represents the resistance arm. From the above formula, it can be seen that in order to balance the lever, the power arm is several times that of the resistance arm, and the power is a fraction of the resistance.

When using a lever, in order to save effort, you should use a lever that is longer than the resistance arm; If you want to save distance, you should use a lever that is shorter than the resistance arm. Therefore, the use of levers can save effort and distance. However, if you want to save effort, you must move more distance; If you want to move less distance, you have to work harder.

It is impossible to achieve it with less effort and less distance. It was from these axioms, on the basis of the theory of the "center of gravity", that Archimedes discovered the principle of the lever, that is, "when the double objects are in balance, their distance from the fulcrum is inversely proportional to their weight." The fulcrum of the rod does not have to be in the middle, and the system that satisfies the following three points is basically a lever:

Fulcrum, force point, force point. The formula reads: Power Power Arm = Resistance Resistance Arm, i.e. F1 L1 = F2 L2 This is a lever.

Power arm extension.

There are also low-effort levers and labor-intensive levers, both of which have different functional performances. For example, there is a pump that is stepped on by the foot, or a juicer that is pressed by hand, which is a labor-saving lever (force arm > force distance); But we have to press down a large distance, and there is only a small movement on the stressed end. There is also a laborious lever.

For example, the crane on the side of the road, the hook for fishing things is at the tip of the whole rod, the tail end is the fulcrum, and the middle is the hydraulic press (torque > force arm), which is the laborious lever, but the laborious exchange is that as long as the middle force point moves a small distance, the hook at the tip will move a considerable distance. Both levers are useful, but where they need to be used to evaluate whether they need to save effort or range of motion. There is also something called the axle, which can also be used as a lever, but the performance may sometimes be added to the calculation of rotation.

The ancient Greek scientist Archimedes had such a famous saying that has been passed down through the ages:"If you give me a fulcrum, you can pry up the earth"This sentence is not only an inspiring aphorism, but also has a strict scientific basis.

Archimedes famously said that as long as the lever is long enough and there is a fulcrum, the earth can be leveraged.

This is what Archimedes said, according to the principle of physical leverage, the force multiplier arms on both sides of the fulcrum are equal.

Discovered by Archimedes, the principle of leverage.

Your questions are all wrong, you should have to give a fulcrum...

Hahaha.

The best excuse you can find for your abilities.

Principle of Leverage Balance: The main focus is to highlight the impact of leverage on balance.

However, I personally think that this sentence has the meaning of "everything is possible".

When we were in junior high school, we learned a sentence in physics books, if you give me a lever, I can pry up the whole earth, and here we learn the principle of levers, which was proposed by Archimedes. So how long of leverage do you need to pry the earth? If the moon is used as a fulcrum to pry the earth, then the distance from the earth to the moon is about 38,000 kilometers, and this unit cannot be a meter or a kilometer as a unit of length, but is measured in light years.

The radius of the solar system is so long. Because the mass of the earth is very large, the lever arm required is very long, at least as long as the radius of the solar system, to pry the earth.

It doesn't matter how long it should be, it stands to reason that as long as there is a fulcrum and a lever long enough, it can be leveraged, but this is an idealized state, and the reality is impossible.

It takes a 346.5 billion light-year lever to move the Earth, which is 40 times the diameter of the Milky Way.
