What does scale mean
Scales, also known as' weighing ', are traditional weighing tools, which are mostly used in the vegetable market. The main body of the scale is a wooden or bamboo pole, with a large hook at one end and a heavy weight (weight) hanging at the other end. Hang the thing to be measured on the hook, move the weight, use the lever principle to balance both sides and take the reading. There is another saying 'never leave the weight' to describe the two often appear together.
How do Libra scales read
Libra is one of the zodiac signs. It is located between Virgo and Scorpio, just in front of Scorpio's head. Several main stars in Libra are square, among which dixi4 is the only green star that can be recognized by the naked eye, which is worth observing. Generally, the Sun runs in Libra from November 1 to November 23 every year. The two solar terms of the beginning of winter and light snow of the lunar calendar are in Libra. Libra was originally part of Scorpio. Although it was called the Libra in Indian and Middle Eastern cultures before ancient Rome, it was not until Caesar's time in the first century BC that the Romans found that when the sun moved near Libra, it was the equinox solar term of day and night that Libra officially came into being. It is said that the Libra of Demeter, the goddess of truth and justice, specializes in measuring good and evil in the world. Therefore, when Demeter rose to heaven and became Virgo, the God also raised her Libra measuring good and evil to heaven and became Libra next to Virgo. It can be seen that people take the meaning of the scale of the scale, that is, Cheng. Therefore, the correct official pronunciation of Libra should be: 'Tian Cheng Zu', rather than the usual pronunciation: 'Tian Ping Zu'.
What do you think of the weight scale
An ordinary pole scale has a maximum measuring range of 20 kg. There are two rows of scales on the body of the scale bar, two lifting ropes at one end of the weighing hook, and the weight weighs 1 kg. We all know that the pole scale uses the principle of pole and bar. The lifting rope close to the weighing hook can weigh objects with greater mass, and the lifting rope on the left has a smaller range. There are 10 small cells between 1 and 2, so the minimum unit is 1 and 2. There are 10 small grids between 5 and 10, so the minimum unit is 5 Liang. Understanding these is the same as the scale on the ruler. Try it quickly.
