Triple beam balance structure
The Triple beam balance is so named because it has three horizontal bars with scales. The Triple beam balance has three sets of yardages but no weights. First, use the yardage with the largest scale. If the pointer does not return to zero, then adjust the yardage with the smaller scale. A Triple beam balance has three horizontal bars, each of which has weights of different masses placed on it. By moving the position of the weights, the resistance to the opposite side of the object can be adjusted with the fulcrum of the balance as the center. The object to be tested is placed in the weighing paper or the weighing pan and then placed on the weighing pan of the balance.
A Triple beam balance mainly uses the positions of three weights on three horizontal bars to measure the mass of an object.
The top bar has ten engraved teeth, ranging from 0g, 1g, 2g, *.. all the way from left to right to 10g.
On the crossbar in the middle, there are ten engraved teeth from zero to 100 grams, and each engraved tooth is in units of 10 grams.
The bottom bar is from zero to 1 gram, and is first divided into ten scales by the large scale, and each scale is in 1.0 gram units. Then divide each 0.1 gram unit in half by the middle scale, and each middle scale is 0.05 gram. Finally, the small scale divides each two large scales into ten equal parts, and each small scale is 0.01 grams.
There are two short rods on the right straight beam of the three horizontal bars of the Triple beam balance, which can be hung with weights. yard, the weighing value of the balance will increase by 100 grams.
