- A scale or balance is a device used to measure weight or mass. These are also known as mass scales, weight scales, mass balances, and weight balances.
The traditional scale consists of two plates or bowls suspended at equal distances from a fulcrum. One plate holds an object of unknown mass (or weight), while known masses are added to the other plate until static equilibrium is achieved and the plates level off, which happens when the masses on the two plates are equal. The perfect scale rests at neutral. A spring scale will make use of a spring of known stiffness to determine mass (or weight). Suspending a certain mass will extend the spring by a certain amount depending on the spring's stiffness (or spring constant). The heavier the object, the more the spring stretches, as described in Hooke's law. Other types of scales making use of different physical principles also exist.
Some scales can be calibrated to read in units of force (weight) such as newtons instead of units of mass such as kilograms. Scales and balances are widely used in commerce, as many products are sold and packaged by mass.
The balance scale is such a simple device that its usage likely far predates the evidence. What has allowed archaeologists to link artifacts to weighing scales are the stones for determining absolute mass. The balance scale itself was probably used to determine relative mass long before absolute mass.
The oldest attested evidence for the existence of weighing scales dates to the Fourth Dynasty of Egypt, with Deben (unit) balance weights, from the reign of Sneferu (c. 2600 BC) excavated, though earlier usage has been proposed.Carved stones bearing marks denoting mass and the Egyptian hieroglyphic symbol for gold have been discovered, which suggests that Egyptian merchants had been using an established system of mass measurement to catalog gold shipments or gold mine yields. Although no actual scales from this era have survived, many sets of weighing stones as well as murals depicting the use of balance scales suggest widespread usage.
Examples, dating c. 2400-1800 BC, have also been found in the Indus River valley. Uniform, polished stone cubes discovered in early settlements were probably used as mass-setting stones in balance scales. Although the cubes bear no markings, their masses are multiples of a common denominator. The cubes are made of many different kinds of stones with varying densities. Clearly their mass, not their size or other characteristics, was a factor in sculpting these cubes.
In China, the earliest weighing balance excavated was from a tomb of the State of Chu of the Chinese Warring States Period dating back to the 3rd to 4th century BC in Mount Zuojiagong near Changsha, Hunan. The balance was made of wood and used bronze masses.

A simple device beautifully reconstructed. Nice job!
Thank you very much!
I don't have rights to judge your way of work because I'm not a restoration guy but yes I'd suggest slowly with time you can improve your workshop looks & ambience along with a bit of editing, that would help you a lot in my view. Waiting to see your next project. ❤️
Yes, dear friend, why not?
Thank you for your beautiful look. Thank you for telling me to support me.
Great job. I just would like to know what you use to remove the rust (that liquid), what that putty is to fill in the holes, etc. Thanks

After heat effect the balance spring streanth may be decrease is not it?
Yes, that's right, it's exactly the same, and for this reason, I introduced the heat from the bottom, that is, from where there is no pressure on the spring.
Nice😊
Thank you

Needed to have brass pins to hold the brass faceplate on not the cheap aluminum pins that were used. Otherwise very interesting.
Thank you for your advice dear friend
Безмен))
thank you my bro
Low quality. If you will be happy of your work than it is okay. For me lot of improvements to be done
Thank you for your opinion, my good friend, I am never satisfied with my work, never.
And I am constantly improving. My past videos show this well. Thank you for your opinion and thank you for your beautiful look.
I would not say low quality. Yes there is always a room for improvement (even for big UA-camrs) but he gave good effort & did a good work in my view. Perfection comes with time & he is still growing on UA-cam.
@@KinG_KJ I am proud to have friends like you. You cheer me up. And my dear King KJ, thank you for cheering me up. You really made me feel better. I wish you the best wherever you are in the world. Your friend Behnam ❤️
@@KinG_KJ I thought about the subject again. Yr right not low quality, limited quality is more precise expression. To grow on YT neds much more. Beginning with using correct tools and knowledge of material etc.
I wanted to see how you are going to restore it, but you were too pushy and wanted me to like the video before watching it. that I cannot do. will not watch; thank you.
As you wish, dear friend, you can not watch my video at all, you can dislike my video, you can not come to UA-cam, I can't tell you anything, can I???
bien bon travail :-)
Merci beaucoup mon frère
