Archimedes law
2.The system was notaccording to the underwater weighing method to measure body volume ,butthe archimedes’law.
3.The density and micro-hardness are determined according to Archimedes law. Detection results exhibit that the hardness of the glass decreases and the density increases with the increment of Bi_(2)O_(3) content.
4.The microstructure, density, apparent porosity, room temperature mechanics and oxidation resistance of silicon carbide ceramic had been systematically analyzed through XRD, SEM techniques as well as Archimedes law, three-point bending, single edge notched beam bending and Vicker’s hardness indentation methods.
5.Based on analyzing the formal density measurement of solid matters,in this article,we bring forward a kind of density measurement method for rock and ore material based on the Archimedes law, have finished the designing of density instrument hardware circuit,supply the technical index of density instrument and the error analysis of measurement result.
6.DM-2 density instrument has many disadvantages,such as low precision,difficult to display result,restricted by variety of the samples,complicated to operate,etc. Based on analyzing the formal density measurement of solid matters,the paper brought forward a kind of density measurement method for the rocks and minerals based on the Archimedes law,finished the designing of density instrument hardware circuit and the compiling of support software,supplied the technical index of density instrument and the error analysis of measurement result.
7.Archimedes' law can be explained here like this: When a cube is completely under water, if the weight of water which is pushed aside is greater than the weight of the cube. It will go up and stay on top of the water. If it is less than the weight of the cube it will go down in the water. If it is the same as the weight of the cube, it will neither stay on top nor go down. They have come to balance each other.
9.For example, the book of "Study on the Balance of Plane figures " involves the famous Archimedes Lever Law;
