Although the scale is small, it weighs thousands of pounds. He slammed the false fire.

Although the scale is small, it can press thousands of pounds and use the lever principle. The lifting rope is equivalent to the fulcrum, the weighing pan is equivalent to the resistance point, and the weighing stone is equivalent to the force point, because the distance from the force point to the fulcrum is greater than the distance from the force point to the fulcrum, so it is a labor-saving lever.
Related Notes:Equivalent to weights. If a small piece of the scale of the rod scale with an accurate scale is excavated, the reading is larger than the actual mass of the object.
Weighing effect: It is because everyone has a scale in their hearts, but the scales are not consistent and fixed. As the psychology changes, so does the scales.
When the scale becomes smaller, the weight of the object it weighs is larger, and when the scale becomes larger, the weight of the object it weighs is smaller. People's perception of things is influenced by this scale. In interpersonal communication, learn to keep a low profile, so that others will not blame you too much.

Using the principle of leverage, you can use this principle to carry out related work very well, this method is very convenient.
-
The principle of leverage, although the scale may seem small, can play a very important role in this thing.
-
Although the scale is small, it can be understood as "a small number can represent a big meaning". The number on the weighing stone represents the weight, although the weighing stone is small, but it can press the object of thousands of catties, this is because it is in equilibrium with the weighed object, that is, the weight of the weighing stone is equal to the weight of the weighed object. In the same way, the number is small, but the weight it represents is huge.
Therefore, "although the scale is small and weighs thousands of pounds", you can guess the three numbers respectively. 0 represents the weight of the weighing stone, 1 represents the weight of the weighed object, and 2 represents the total weight of the weighing stone and the weighed object.
-
Guess what the three numbers are.

"Although the scale is small, it can weigh thousands of catties", it seems that a small piece of the scale can hold down the weight of a thousand catties. The metaphor is unobtrusive on the outside, but it actually works. "Although the scale is small, it can press thousands of catties", which is a typical phenomenon in the use of lever tools, such as: rod scale.
The rod scale uses the principle of leverage. The position of the rope is equivalent to the fulcrum of the lever, the position of the weighing pan is equivalent to the resistance point, the position of the weighing stone is equivalent to the force point, the gravity of the weighed object is equivalent to the resistance, and the gravity of the weighing stone is equivalent to the power force.
Sentence formation: 1. Although the urine bubble is large, there are no catties, and although the scale is small, it can press thousands of catties.
2. The size is relative, although the scale is small, it can weigh thousands of catties, I don't know what to do more and more, and the more scruples I have.
3. Although the scale is small, it can weigh thousands of catties, but Ganluo is not a prime minister at the age of three.
4. You haven't heard that people can't look good, and the sea can't fight! Although the scale is small, it can weigh thousands of pounds, I haven't seen the real chapter, how do you know how powerful I am!
5. Although the scale is small, it can press thousands of catties; Although the scale is small, it can weigh people's hearts; Although the interests are high, do not take ill-gotten gains.

Leverage principle. Leverage principle. The rope on the scale rod is the fulcrum, and the power arm at both ends * power = resistance arm * resistance.
Although people of small status and qualifications, they play a vital role in the collective. It also refers to the details that determine success or failure.
According to the lever balance condition, it can be obtained: the gravity of the weighing stone The distance from the weighing stone to the fulcrum = the gravity of the kilogram object The distance from the kilogram object to the fulcrum. The mass of the scale is relatively small, but its force arm is relatively large; On the contrary, although the mass of the jack object is large, the force arm is relatively small; Therefore, "although the scale is small and the weight is thousands" can be explained by the principle of lever balance (or leverage).
Application of Leverage Balance:
1. When using a lever, in order to save effort, you should use a lever that is longer than the resistance arm.
2. 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.
3. 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."
