A person holding a wooden stick prying the earth What does it mean Quick answer If the answer is com

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

Archimedes was the first to propose the principle of leverage in his book On the Equilibrium of Plane Figures. He first regarded some empirical knowledge in the practical application of leverage as "self-evident axioms", and then proceeded from these axioms and used geometry to derive the principle of leverage through rigorous logical argumentation. These axioms are:

1) Hang equal weights at the ends of the weightless rod at an equal distance from the fulcrum, and they will balance;

2) Hang unequal weights at the same distance from the fulcrum at both ends of the weightless rod, and the heavy end will tilt downward;

3) Hang equal weight at the two ends of the weightless rod at an unequal distance from the fulcrum, and the far end will be tilted down;

4) The action of one weight can be replaced by the action of several evenly distributed weights, as long as the position of the center of gravity remains the same. Conversely, several evenly distributed weights can be replaced by one that hangs at their center of gravity.

5) The center of gravity of similar graphs is distributed in a similar way ......

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."

Bite off more than one can chew. Huge potential.

Responsibility. Save.

The power of knowledge is infinite

It can be said in a sentence that "give me a fulcrum in the universe, I can pry up the earth" As for who said it, I forgot, you go check it!

I'm telling you that the man is Archimedes.

Archimedes said: Give me a fulcrum, and I can pry up the whole earth. But the problem is that the fulcrum doesn't exist yet, if you really want to do it, then you have to read a book!!

The implication is: reading is only a necessary condition for your success, but it is not your goal (like the fulcrum of the pole, you must have a fulcrum if you want to pry the earth, but it is your goal to pry the earth) But if you want to achieve the goal, you must have knowledge.

That book must be a physics book. You see what a domineering thing it is to be good at physics!

4.I live in a city where many wild animals are slaughtered in restaurants, I hear the voice of a county magistrate's wife who is worried about her husband's dismissal because he is out hunting, and I hear the roar of the lovely animals in the mountains falling.

5.There are those who only have their own interests and do not care about the feelings of Mother Earth6We should protect nature and not let it be harmed

7.Be sure to protect the planet.

1. As a primary school student, what would you do to protect the earth?

Answer: 1. Promote environmental protection knowledge. 2. Take care of flowers and plants. 3. Save every drop of water and every kilowatt-hour of electricity.

2. What is the meaning of the article titled "Tears of the Earth"?

A: It arouses people's thinking and gives them inspiration.

Just talk about what you think about protecting the environment.

We have to cherish the earth now, and if we don't cherish it well, then the only thing we can survive on is the earth. We have only one earth, cherish !!
