How to mark the scale of steelyard?

Determine the zero scale first, don't put objects, hang the heavy objects here, and the position just balanced is the zero scale, and then determine the scale. Using the lever principle, taking the knob as the fulcrum, the weight of the heavy object multiplied by the arm of force is equal to the weight of the object multiplied by the arm of force, and the scale is even. Just mark the corresponding quality value on the corresponding scale line;

The steelyard consists of the first lever, and its center of gravity is at the outer end of the fulcrum. When weighing, according to the weight of the weighed object, move the weight and the weighting rope on the balance beam to keep the balance. According to the star point on the balance beam corresponding to the counterweight rope during balance, the quality indication value of the weighed object can be read out. Accurate steelyard must meet the weight × scale spacing of 65438 +0kg = the distance from the lifting button to the hanging point of the weighing pan;

The main value of steelyard

1. As a traditional weighing instrument independently invented by China, the steelyard is no less scientific than the electronic scale. It has been used in China for thousands of years, and its social value can be said to be everywhere, which proves that the steelyard still has its application value, and in a certain sense, it still retains the original ecological and sustainable green measurement tool;

4. The steelyard is more humanized than the electronic scale. In business, the seller shouted "Look, the scale is high" with a big smile on his face. The buyer looked at the steelyard tilted high, and felt that he really got great benefits and paid with joy. It has humanistic characteristics, and the business done with steelyard reflects the uniqueness of China culture.

13. Its rise and fall records the history of social life changes. Under the global background that the big industrial civilization challenges the handicraft civilization, China has restricted, criticized, reformed and cracked down on the traditional steelyard and its production for decades in terms of ideology, technical methods and industrial system.
